The soil horizon containing only organic material is the O horizon.

What is the O horizon?

The O horizon, which is the soil layer containing the most organic matter, is also known as the organic layer. The organic layer includes both live and dead plant roots and decomposed plant and animal residues.

This horizon can be very thin in some soils or as much as several meters thick in some organic soils. Because of its abundance of organic matter, the O horizon is often dark in color and has a spongy texture. This soil layer is sometimes known as the surface layer.The O horizon is found in soils that have experienced natural soil formation over a long period of time. The development of this layer of soil is affected by a variety of factors, including climate, vegetation, and the underlying bedrock, which all play a role in soil development. The soil's pH level and other chemical properties can also affect the amount of organic matter present in the O horizon. Additionally, human activity can affect the development and composition of this soil layer.

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.

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.

Hence, when we see Venus in its full phase, Earth would appear as a new phase to a hypothetical Venetian. The answer is first quarter.

At night, a process called radiation cooling causes the air on the mountain slopes to cool more quickly than in the valley below. This creates a temperature inversion, where the air temperature at the top of the mountain is cooler than at the base.  

The temperature inversion also has other effects, such as creating a stable layer of air that traps pollutants near the ground and limits visibility. Additionally, the process helps to distribute moisture more evenly throughout the environment.

This is a vital part of many mountain ecosystems, and an important factor to consider when studying climate patterns and air quality in mountainous areas.

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.

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.

Of the three water potentials that make up total soil-water potential Compaction affects matric potential.

The hydraulic potential, the gravitational potential, and the matric potential are the three water potentials that contribute to the total soil-water potential.

Matric potential is the most affected by compaction.

Compaction has a negative impact on the overall structure of the soil. This can lead to a reduction in water and nutrient availability to plants. In a compacted soil, there is a reduction in pore space, and the particles are closer together.

The reduced pore space means that the matric potential is affected the most by compaction.

The matric potential of soil is the energy that holds water molecules in the soil against gravity. The matric potential increases as the pore size decreases, making it more difficult for water to move through the soil.

This can result in soil drying out faster and nutrient deficiencies as the roots are not able to access the available water and nutrients.

Soil compaction can occur when the soil is compressed by natural or human-made processes, reducing the pore space between soil particles.

As a result, the soil's ability to retain water decreases, and the matric potential becomes more negative. This negative potential makes it more difficult for plant roots to extract water from the soil, which can lead to decreased plant growth and yield.

Thus, soil compaction can significantly affect the matric potential and, therefore, the ability of plants to access water in the soil.
