Weathering
Correct Answer
D. WeatheringExplanation
Weathering is the correct answer because it refers to the process of breaking down rocks and soil through contact with the atmosphere. This can occur through various mechanisms such as physical, chemical, and biological processes. Erosion, on the other hand, refers to the transportation of weathered materials by wind, water, or ice. Thermal expansion is the expansion of materials due to heat, and abrasion is the process of wearing down materials through friction or rubbing.Rate this question:

The breaking down of rocks and soil by contact with heat, ice, water, or pressure is called...
- A.
Chemical weathering
- B.
Physical weathering
- C.
Ice wedging
- D.
Thermal weathering
Correct Answer
B. pHysical weatheringExplanation
Physical weathering refers to the process of breaking down rocks and soil through mechanical forces such as heat, ice, water, or pressure. This type of weathering does not involve any chemical reactions. Instead, it occurs when physical forces cause rocks to fracture or break apart into smaller pieces. Examples of physical weathering include freeze-thaw cycles, where water seeps into cracks, freezes, and expands, causing the rock to break, and abrasion, where rocks rub against each other and wear down over time. Therefore, physical weathering is the correct answer in this context.Rate this question:

- A.
Physical weathering
- B.
Ice wedging
- C.
Thermal weathering
- D.
Chemical weathering
Correct Answer
D. Chemical weatheringExplanation
Chemical weathering refers to the process in which chemicals present in the atmosphere react with rocks, soil, and minerals, causing them to break down and undergo changes. This process can occur due to various chemical reactions such as oxidation, hydrolysis, or dissolution. Unlike physical weathering, which involves the mechanical breakdown of rocks, chemical weathering alters the composition and structure of the materials. Therefore, the given answer, "Chemical weathering," accurately describes the effect of chemicals in the atmosphere on rocks, soil, and minerals.Rate this question:

What is Ice Wedging?
- A.
The process of rock being broken apart by water freezing, expanding, and making cracks.
- B.
The process of rock being broken apart by heating up in the day and expanding and cooling off at night and impending.
- C.
Ice caps melting from global warming.
- D.
None of the above
Correct Answer
A. The process of rock being broken apart by water freezing, expanding, and making cracks.Explanation
Ice wedging is the process of rock being broken apart by water freezing, expanding, and making cracks. When water seeps into cracks in rocks and freezes, it expands and exerts pressure on the surrounding rock, causing it to crack and break apart. This process is particularly effective in cold climates where there are freeze-thaw cycles, as the repeated freezing and thawing of water can gradually break down rocks over time.Rate this question:

What is Thermal Expansion?
- A.
The process of rock being broken apart by heating up in the day and expanding and cooling off at night and impending.
- B.
The process of rock being broken apart by water freezing, expanding, and making cracks.
- C.
Mountains expanding because of the warmth of the Earth.
- D.
None of the above

Management rules for keeping soil from being eroded away is called...
Correct Answer
soil conservationExplanation
Soil conservation refers to the set of management practices and techniques implemented to prevent or minimize soil erosion. It involves various strategies such as contour plowing, terracing, crop rotation, and the use of cover crops. These methods help to protect the topsoil from being washed away by wind or water, thus preserving its fertility and preventing environmental degradation. Soil conservation is crucial for maintaining sustainable agriculture, preventing land degradation, and preserving natural resources for future generations.Rate this question:

Correct Answer
soilExplanation
Broken down materials like rocks, dirt, and leaves form a mixture that is commonly known as soil. Soil is a natural resource that provides a medium for plants to grow and is essential for agriculture. It is composed of organic matter, minerals, water, and air, and plays a vital role in supporting the Earth's ecosystems. Soil is formed through a process called weathering, where physical, chemical, and biological processes break down larger materials into smaller particles over time.Rate this question:

Correct Answer
soil horizonExplanation
A layer of soil parallel to the surface, having distinct characteristics made by how the soil was formed is called the soil horizon. Soil horizons are formed as a result of various processes such as weathering, deposition, and organic matter accumulation. Each horizon has its unique set of characteristics, including color, texture, and composition, which are influenced by factors like climate, parent material, and time. These horizons play a crucial role in determining soil fertility, drainage, and overall soil health.Rate this question:

Correct Answer
properties of soil
characteristics of soilExplanation
Texture, structure, compaction, and organic matter are all properties of soil. These properties help to determine the quality and fertility of the soil. Texture refers to the size of the soil particles, while structure refers to the arrangement of these particles. Compaction refers to the density and firmness of the soil, and organic matter refers to the presence of decomposed plant and animal materials in the soil. Together, these properties contribute to the overall characteristics of the soil, including its ability to hold water, support plant growth, and provide nutrients.Rate this question:

It depends mostly on climate, exposure, and size to determine how long it will take to weather
Correct Answer
E. It depends mostly on climate, exposure, and size to determine how long it will take to weatherExplanation
The rate of weathering refers to how long it takes for rocks and minerals to break down or decay due to various environmental factors. This process is influenced by climate, exposure to weather elements, and the size of the rocks or minerals. Different climates and levels of exposure can accelerate or slow down the weathering process, while larger rocks or minerals may take longer to weather compared to smaller ones. Therefore, the rate of weathering cannot be determined solely by a specific time frame but depends on these factors.Rate this question:
