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

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.

What is Global Temperature?
The average temperature of the planet Earth is referred to as global temperature. The temperature is calculated by combining air temperatures over land and sea surface temperatures. Earth's climate system's various components, such as the atmosphere, the ocean, the land surface, and the cryosphere (ice and snow-covered areas), interact with one another in intricate ways to create the planet's weather and climate.
This indicates that changes in one component of the climate system can have significant effects on the other components.Water vapor is an essential atmospheric constituent, and it has an effect on climate. Water vapor is a greenhouse gas, which means that it absorbs the radiation from the sun and emits it in various directions.
The heating of the Earth's atmosphere is caused by water vapor's absorption of long-wave radiation. As a result, an increase in temperature in the Earth's atmosphere causes an increase in water vapor. As a result, a positive feedback loop is formed, causing the Earth's temperature to continue to rise.

of the three water potentials that make up total soil-water potential, which one would be most affected by compaction?
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.

The enormous earthquake that took place on 26th December, 2004 just off the coast of Sumatra, generated a tsunami that killed over 245,000 people.
A tsunami is a series of ocean waves caused by an underwater earthquake, landslide, or volcanic eruption. Large waves, sometimes reaching up to 100 feet in height, can cause significant destruction to coastal communities and homes.Tsunamis are frequently caused by earthquakes that take place beneath the ocean's surface. When an earthquake occurs, the friction between two tectonic plates releases a huge amount of energy, causing the water above to ripple outward. This energy can cause significant waves to form and quickly travel across the ocean.
Tsunamis are difficult to see and frequently travel faster than a person can run, making them difficult to escape. The strength of the water's force is the other reason for their harm. Tsunamis have the power to knock over buildings and ships, as well as carry individuals out to sea.Tsunamis can cause widespread damage, and the best way to avoid being affected is to evacuate to higher ground as soon as possible.
