The upper portion of a glacier where individual grains of ice does not move relative to one another is called the firn line.
Firn is the intermediate stage between snow and glacial ice, and forms when snow is compacted under its own weight and recrystallizes. This line is found at the top of the glacier, where temperatures and pressures are too low for recrystallization.
The firn line marks the boundary between the accumulation zone, where more snow accumulates than melts or sublimates, and the ablation zone, where more snow melts or sublimates than accumulates. It is an important reference point for measuring glacier mass balance, as any movement of the firn line indicates a change in the amount of snow accumulation or snow melts.

based on the distribution of magnetic anomalies, where is the oldest oceanic crust found? the youngest? what are their ages?
The oldest oceanic crust is found in the central Pacific Ocean and the youngest oceanic crust is found along the Mid-Atlantic Ridge. The oldest oceanic crust is about 180 million years old and the youngest oceanic crust is about 3 million years old.
The distribution of magnetic anomalies helps geologists identify the age of the oceanic crust. Magnetic anomalies are created when new oceanic crust is formed due to volcanic activity and tectonic plate movement. The magnetism of the oceanic crust is usually aligned with the Earth's magnetic field when it is first formed. As the Earth's magnetic field reverses, the magnetism of the oceanic crust is "frozen in time" and helps scientists measure the age of the crust.
The oldest oceanic crust is found in the central Pacific Ocean because it has been around the longest and hasn't moved much due to tectonic plate movement. The youngest oceanic crust is found along the Mid-Atlantic Ridge because this is where new oceanic crust is constantly being formed due to tectonic plate movement and volcanic activity.
By studying the distribution of magnetic anomalies, scientists can accurately measure the age of the oceanic crust and identify where the oldest and youngest crust can be found.

Further west from the deep U.S. trough, Eastern Alaska, as well as Yukon and British Columbia, Canada, were being impacted by a ridge.
A ridge of high pressure is impacting Eastern Alaska, Yukon and British Columbia in Canada, further west from the deep U.S. trough. A ridge of high pressure is an area of high atmospheric pressure, which is associated with fair weather, light winds and generally pleasant conditions. This ridge is formed when two air masses move away from each other, causing the air pressure in the area to increase. A ridge is typically indicated on a weather map by a line of red L's. The L's are placed on the map in the direction of the wind flow around the ridge, with the point of the L representing the area of highest atmospheric pressure.
The increased atmospheric pressure caused by the ridge produces lighter winds and warmer temperatures. The warmer temperatures and decreased wind speeds generally lead to more stable weather conditions and less precipitation. The ridge can also bring dry and sunny conditions, as well as a decrease in storm activity. These effects can be felt further downwind of the ridge, making it a welcomed feature in many areas.
In contrast, a trough is typically associated with low-pressure areas that produce wet, stormy weather conditions, as well as cool temperatures. This is because the low-pressure system promotes the formation of clouds and precipitation, which can reduce the amount of solar radiation that reaches the Earth's surface.

1 pts as erosion strips off the tops of mountains, the mountains will "bob" upward. this is an example of
This phenomenon is known as isostatic rebound. Isostatic rebound occurs when the pressure exerted by the overlying material is relieved, usually caused by erosion. It is believed that this process occurs due to the removal of material, such as ice or sediment, from the upper layers of the mountain.
As this material is removed, the weight of the mountain decreases, causing the mountain to slowly “bob” upwards. This process is gradual and can take hundreds or even thousands of years to fully complete. Isostatic rebound plays an important role in the overall geology of a region, and can often result in dramatic landscape changes. For example, recently glaciated areas are often characterized by low relief, whereas regions that have experienced isostatic rebound often have steep terrain.

If we see Venus in its full phase, Earth would appear as a new phase to a hypothetical Venetian. The answer is first quarter.
What is the meaning of the term "full phase"?
The term "full phase" refers to the time when the planet is positioned behind the Sun in the Earth-Sun-planet alignment. This alignment causes the planet to appear fully illuminated from Earth’s point of view because it reflects all of the sunlight that is falling on its surface.
The orbital path of Venus is smaller than that of Earth because it is closer to the Sun. When Venus is on the far side of the Sun (as viewed from Earth), we can see its full illuminated face.
At that moment, the Sun-Earth-Venus angle is 180 degrees, and Venus is on the opposite side of the Sun from the Earth.

Whatdoes the theory of plate tectonics have that Wegener's hypothesis of continental drift did not have?
Answer: The theory of plate tectonics has a mechanism for explaining how the continents move, while Wegener's hypothesis of continental drift did not.
Explanation: In the early 20th century, Alfred Wegener proposed the hypothesis of continental drift, which suggested that the continents were once joined together in a single landmass called Pangaea, and had slowly drifted apart over millions of years. However, Wegener did not have a mechanism to explain how the continents moved.
In the 1960s, the theory of plate tectonics was developed, and it provided a mechanism for understanding how the continents move. The theory of plate tectonics suggests that the Earth's lithosphere (which includes the crust and the uppermost part of the mantle) is divided into a series of plates that move relative to each other. The motions of the plates are driven by convection currents in the mantle.
At the boundaries where the plates meet, different phenomena occur. At divergent boundaries (such as the Mid-Atlantic Ridge), new crust is formed as magma rises to the surface and hardens, pushing the plates apart. At convergent boundaries (such as the Andes Mountains), plates collide and one is forced under the other (in a process called subduction). At transform boundaries (such as the San Andreas Fault), plates slide past each other.
The theory of plate tectonics thus provides a mechanism for explaining how the continents move over time. As new crust is formed at divergent boundaries and old crust is destroyed at subduction zones, the plates move apart and the continents drift. This explains why the continents are moving today and have been moving over geological time scales, and how they have been in different positions in the past.
Overall, while Wegener's hypothesis of continental drift was a significant step in understanding the evolution of the Earth's continents, it was the theory of plate tectonics that provided the more complete and explanatory picture, by proposing a mechanism for how the continents move.

Water velocity in a stream varies based on many factors but is usually greater at the mouth than the head. The part of a stream commonly having the highest gradient is head.
Stream is defined as a body of water, running or moving continuously in a channel or course of considerable width and length. There are a number of different types of streams, each characterized by its size, location, and water velocity.
Some of the important factors that affect water velocity in a stream include the slope of the land, the amount of water in the stream, the shape of the streambed, and the type of sediment in the streambed.
Water velocity is the speed of water in a stream or river. It is the distance the water travels over a particular period of time. Water velocity in a stream is influenced by many factors such as the streambed, the shape of the channel, the amount of water in the stream, and the slope of the land, among others.
Gradient refers to the steepness or slope of a stream channel. The highest gradient in a stream is found at the head. The head is the point where the stream begins or the location where the stream gets its water. As the stream flows downstream, the gradient decreases, and the water velocity decreases.

which of the following are geologic settings where travertine can form? choose one or more: a. in glacial lakes b. in caves c. in fast-moving rivers d. near hot springs e. in swamps
Travertine can form in a variety of geologic settings, including in caves, near hot springs, and in fast-moving rivers. Therefore the correct option is option A, B and C.
In caves, travertine forms as a result of carbon dioxide in the air dissolving in water. This results in an increase in the acidity of the water, which in turn dissolves the rock the cave is made of and deposits the resulting sediment in the form of travertine.
Near hot springs, the water is saturated with dissolved minerals such as calcium carbonate, which can also be deposited in the form of travertine.
In fast-moving rivers, the increased turbulence can cause the suspended sediment in the water to become trapped and deposited in the form of travertine.

The term that describes soil that remains in place after having formed by weathering of the underlying bedrock is residual soil.
What is residual soil?
Residual soil, also known as residuum, is soil that forms from the weathering of bedrock that has remained in place. This soil is formed by in situ weathering and usually remains where it is formed. The weathering processes cause the bedrock to disintegrate into small particles, resulting in the formation of residual soil.
Residual soils are usually found on slopes and hilltops, where weathering is highest, and are often composed of coarse particles due to the intense weathering that occurs. They are generally thick and can be of varying depths depending on the bedrock they have formed from. The soil is typically rocky and nutrient-poor, which limits plant growth. Residual soils are classified as 4th-order soils according to the Soil Taxonomy. The Soil Taxonomy ranks soils into 12 orders based on their characteristics.

which of the following fundamental properties of mars could explain why it once had a global magnetic field but later lost it? group of answer choices its small size its larger distance than earth from the sun a rotation rate that is slightly slower than earth's its axial tilt
The fundamental property of Mars that explains why it once had a global magnetic field but later lost it is its small size. Therefore the correct option is option A.
Mars lost its magnetic field and its atmosphere over time because its core cooled and solidified, according to NASA. The Mars crust, which is not divided into tectonic plates like the Earth's, is an average of 50 kilometers thicker than the Earth's crust.
The processes responsible for creating the Earth's magnetic field are not present on Mars, according to scientists. As a result, Mars is unable to generate the long-lasting magnetic field that shields its atmosphere from the solar wind.
Mars once had a global magnetic field, but it has since lost it due to the planet's small size, which means that its core cooled more quickly than the Earth's.
As a result, Mars has a partially cooled core that no longer produces a magnetic field, making it more vulnerable to the harsh space environment. The statement "its small size" is the correct answer.

describe the two types of volcanic outcrops discussed in the video by sorting their characteristics.
Volcanic outcrops are classified into two types: intrusive and extrusive. Intrusive outcrops form when molten magma cools slowly beneath the surface of the earth, forming large, distinct crystals. Extrusive outcrops form when molten magma quickly cools upon the earth
Intrusive outcrops are typically made up of igneous rocks such as granite, gabbro, or diorite, and the cooling process allows for the formation of larger crystals.
These larger crystals allow for more intricate and interesting rock formations, and the larger size of the crystals makes them easily visible to the human eye. Extrusive outcrops are typically made up of igneous rocks such as basalt or andesite, and the quick cooling process results in smaller crystals.
Intrusive and extrusive outcrops differ in the way they form and the size of the crystals that make up the rocks. Intrusive outcrops form slowly, creating large, visible crystals, while extrusive outcrops form quickly, creating small, invisible crystals.
Both types of outcrops can be found in many geological settings, and each type has its own unique features that can be explored and studied.

The sand dune (illustrated below) was deposited by wind currents 200 million years ago, which way was the wind blowing wind was blowing from right to left. The correct answer is B) the wind was blowing from right to left.
To determine the wind direction, we need to analyze the sand dune's structure. Sand dunes have two distinct sides: the windward side and the leeward side. The windward side is the side facing the wind, and it has a gentle slope. The leeward side is the side sheltered from the wind, and it has a steeper slope.
In this case, we can see that the left side of the dune has a steeper slope, while the right side has a more gentle slope. This indicates that the wind was blowing from the right, carrying sand grains up the gentle slope on the right side of the dune. Once the wind reached the top of the dune, it lost its carrying capacity, causing the sand grains to fall and accumulate on the steeper left side of the dune, forming the leeward side.
So, considering the structure of the sand dune and the slopes, we can conclude that the wind was blowing from right to left 200 million years ago when the sand dune was deposited. The correct answer is B) the wind was blowing from right to left.
