basalt is an igneous rock that can be found in which volcanic environment?group of answer choicesmid-ocean ridge volcanismhot spot volcanismsubduction zone volcanism

Answers

Answer 1

Basalt is an igneous rock that is most commonly found in volcanoes that form due to subduction zone volcanism.

Subduction zone volcanism is a type of volcanism occurs when one of the Earth's tectonic plates moves beneath another and sinks into the mantle. As the two plates grind against each other, the pressure causes magma to rise up through the lithosphere, forming a volcano.

Basalt is composed of minerals like pyroxene, plagioclase, and olivine, and it forms from the cooling and solidification of lava that is created when the magma rises and erupts. Basalt is one of the most common volcanic rocks and is often used to construct structures such as roads, pathways, and buildings.

if you are at 66 degrees north on first day of winter in northern hemisphere, what will you experience?

Answers

On the first day of winter in the northern hemisphere, if you are at 66 degrees north, you will experience cold temperatures, short daylight hours, and potentially snowfall. The sun will set earlier and the temperatures will drop, often below 0 degrees Celsius (32 degrees Fahrenheit).

This region is well within the Arctic Circle, so you can expect the winter to be cold and dark. During the day, temperatures may not reach above freezing, and in the evening they will drop even further. Snowfall is common and the region will be quite dark, as the sun is much lower in the sky at this time of year. During the winter solstice, the sun may only be visible for a few hours each day in this area.

Temperature in the poles around northern hemisphere is too low for any human settlement, lack of direct sunlight is one of the major reason for this extremely low temperature and harsh climate.

What are the 5 stages of solar system formation?

Answers

The 5 stages of solar system formation are Solar Nebula, Protostar and Protoplanetary Disk, Planetesimals, Protoplanets and  Solar System.

The 5 stages of solar system formation are:

1. Solar Nebula: A cloud of dust and gas, called the solar nebula, begins to collapse due to gravitational forces. As it collapses, the material starts to spin and flatten into a disk shape.

2. Protostar and Protoplanetary Disk: The material in the center of the disk becomes denser, forming a protostar. Meanwhile, the remaining material in the disk starts to clump together, creating a protoplanetary disk around the protostar.

3. Planetesimals: Within the protoplanetary disk, solid particles collide and stick together, forming larger bodies called planetesimals. These planetesimals continue to grow as they collect more material from the disk.

4. Protoplanets: As planetesimals grow and interact, some merge through collisions, eventually forming larger bodies known as protoplanets. Protoplanets continue to evolve and differentiate, developing into the planets we observe in our solar system today.

5. Solar System: Over time, the protostar at the center of the system becomes a fully-fledged star (our Sun), while the remaining protoplanetary disk material is cleared out, leaving the planets, moons, asteroids, and other bodies orbiting the star. This marks the formation of the solar system.

Answers

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.

Answers

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 body waves and surface waves responsible for the most shaking.The seismic wave responsible for the most shaking (and thus, the most damage to human structures) is the surface wave.

What are seismic waves?

Seismic waves are waves that are generated by earthquakes and other disturbances in the Earth's surface, such as explosions, volcanic activity, and landslides.

They are made up of various types of waves, each with its own distinctive characteristics. There are two types of seismic waves: body waves and surface waves.

Body waves are seismic waves that travel through the Earth's interior. P-waves and S-waves are two types of body waves. Surface waves, on the other hand, are seismic waves that travel along the Earth's surface.

Rayleigh waves and Love waves are two types of surface waves.

Surface waves are responsible for the most shaking (and thus, the most damage to human structures).

The reason for this is that they travel more slowly than body waves, which allows them to cause more sustained shaking.

based on the distribution of magnetic anomalies, where is the oldest oceanic crust found? the youngest? what are their ages?

Answers

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.

which term describes a soil that remails in place after having formed by weathering of the underlying bedrock? residual relict transformational transported

Answers

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.

an example of a primary effect of drought is question 15 options: a drop in groundwater levels rolling blackouts a decrease in tourism low dissolved oxygen content in reservoirs

Answers

An example of a primary effect of drought is a drop in groundwater levels.

When droughts occur, one of the most common outcomes is a drop in groundwater levels. As the amount of precipitation drops, the amount of water that enters the soil also drops, resulting in a decrease in groundwater levels. As groundwater levels decline, it becomes more challenging to access enough water to meet the needs of communities and agriculture.

As a result, water scarcity becomes an increasingly serious issue.

Therefore, a drop in groundwater levels is a primary effect of drought. Rolling blackouts, a decrease in tourism, and low dissolved oxygen content in reservoirs are all secondary effects of drought.

Drought is a prolonged dry period in the natural climate cycle that can occur anywhere in the world. It is a slow-onset disaster characterized by the lack of precipitation, resulting in a water shortage.

does the southern hemisphere experience hotter summers and colder winters? i ask this because the earth's perihelion is in winter for the northern hemisphere (around january 3rd)

Answers

Yes, the Southern Hemisphere does experience hotter summers and colder winters. This is because of the way the Earth's orbit around the Sun is tilted relative to its axis of rotation. The Earth's perihelion, or point of closest approach to the Sun, is in January for the Northern Hemisphere, while it is in July for the Southern Hemisphere.

This means that the Northern Hemisphere gets less direct sunlight during winter, causing colder temperatures, while the Southern Hemisphere gets more direct sunlight during summer, leading to hotter temperatures.

The Earth's axial tilt, or obliquity, is responsible for the Earth's seasons. During winter, the Northern Hemisphere is tilted away from the Sun, and during summer it is tilted towards the Sun. Conversely, the Southern Hemisphere is tilted away from the Sun during summer, and towards the Sun during winter. This difference in angle of sunlight causes the Northern Hemisphere to experience colder winters and hotter summers, while the Southern Hemisphere experiences hotter summers and colder winters.

Additionally, the Southern Hemisphere is more exposed to the ozone layer, which absorbs some of the Sun's ultraviolet radiation, leading to slightly higher temperatures. This explains why the temperatures in the Southern Hemisphere are higher than the Northern Hemisphere during the same season.
