What Do You Know About Weathering? Trivia Facts

1.

The breaking down of rocks and soil through contact with the atmosphere is called...

A.

Erosion
B.

Thermal Expansion
C.

Abrasion
D.

Weathering

Correct Answer
D. Weathering

Explanation
Weathering refers to the process of breaking down rocks and soil through various physical, chemical, and biological means. It occurs due to exposure to the atmosphere, including factors like temperature changes, water, wind, and biological activity. Erosion, on the other hand, involves the transportation of weathered material by agents such as water, wind, or ice. Thermal expansion refers to the expansion of materials due to heat, and abrasion refers to the wearing away of materials by friction or rubbing. Therefore, the correct answer is weathering.

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 weathering

Explanation
Physical weathering is the correct answer because it refers to the process of breaking down rocks and soil through physical forces such as heat, ice, water, or pressure. This type of weathering does not involve any chemical reactions, but rather the mechanical breakdown of rocks into smaller pieces. Examples of physical weathering include freeze-thaw cycles, where water expands when freezing and causes rocks to crack, or the abrasion of rocks by wind or water.

The effect of chemicals in the atmosphere on rocks, soil, and minerals is called...

A.

Physical weathering
B.

Ice wedging
C.

Thermal weathering
D.

Chemical weathering

Correct Answer
D. Chemical weathering

Explanation
Chemical weathering refers to the process in which rocks, soil, and minerals are broken down or altered due to the chemical reactions caused by chemicals in the atmosphere. Unlike physical weathering, which is caused by physical forces like wind or water, chemical weathering is a result of chemical reactions between the substances in the atmosphere and the minerals in the rocks or soil. This process can lead to the formation of new minerals or the breakdown of existing ones, ultimately affecting the composition and structure of the rocks, soil, and minerals.

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 by which rocks are broken apart due to the expansion of water when it freezes. When water seeps into cracks and crevices in rocks, it can freeze and expand, exerting pressure on the surrounding rock. Over time, this repeated freezing and thawing cycle can cause the rock to break apart, creating cracks and fractures. This process is particularly common in areas with cold climates where freeze-thaw cycles are frequent.

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

Correct Answer
A. The process of rock being broken apart by heating up in the day and expanding and cooling off at night and impending.

Explanation
Thermal expansion refers to the process in which rocks are broken apart due to the heating up during the day, causing them to expand, and then cooling off at night, leading to contraction. This repetitive expansion and contraction can create stress within the rocks, eventually causing them to crack and break apart. This explanation aligns with the given answer option.

Management rules for keeping soil from being eroded away is called...

Correct Answer
soil conservation

Explanation
Soil conservation refers to the set of management rules and practices aimed at preventing soil erosion. These techniques help to protect the topsoil from being washed away by water or blown away by wind, thereby preserving its fertility and structure. By implementing measures such as contour plowing, terracing, and planting cover crops, soil conservation helps to maintain the health of the soil and ensure its long-term sustainability for agricultural and ecological purposes.

Broken down materials like rocks, dirt, and leaves are called...

Correct Answer
soil

Explanation
Broken down materials like rocks, dirt, and leaves are called soil. Soil is formed through the process of weathering, where rocks and minerals are broken down into smaller particles over time. This process is facilitated by factors such as temperature changes, water, wind, and living organisms. Soil is essential for plant growth as it provides nutrients, water retention, and support for roots. It is also home to a diverse range of organisms that contribute to the overall health and fertility of the soil ecosystem.

Correct Answer
soil horizon

Explanation
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 through various processes such as weathering, decomposition, and accumulation of organic matter. Each horizon has its own unique set of properties, including color, texture, and composition, which are influenced by factors like climate, vegetation, and parent material. These distinct horizons help scientists classify and understand different soil types and their properties, which is essential for agriculture, land management, and environmental studies.

Correct Answer
properties of soil
characteristics of soil

Explanation
Texture, structure, compaction, and organic matter are all properties of soil that help to determine its quality and fertility. These properties refer to the physical and chemical attributes of the soil, such as the size and arrangement of its particles, its ability to hold water and nutrients, its level of compaction, and the amount of organic material present. By understanding and analyzing these properties, scientists and farmers can assess the suitability of soil for different agricultural purposes and implement appropriate management practices to improve its health and productivity.

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 weather

Explanation
The rate of weathering refers to the speed at which rocks and other materials break down and erode due to natural processes. This rate is influenced by various factors such as climate, exposure to elements, and the size of the material. Different climates can have different effects on weathering, with more extreme climates often leading to faster rates of weathering. The amount of exposure to elements like wind, water, and temperature changes also plays a role, as materials that are constantly exposed to these factors will weather more quickly. Additionally, the size of the material can affect the rate of weathering, as smaller particles have a larger surface area and are therefore more susceptible to erosion.
