Weathering and Erosion Quiz

Weathering is the process of breaking down rocks, soil, and minerals through contact with the Earth's atmosphere, waters, and biological organisms.

Answer explanation

The correct choice is 'weathering' as it directly defines the process of breaking down rocks, soil, and minerals through interactions with the atmosphere, water, and biological organisms.

The movement of sediment from one place to another is the process of _________________________.

Answer explanation

The movement of sediment from one place to another is called erosion. Erosion involves processes like water flow, wind, and ice that transport soil and rock materials, reshaping landscapes over time.

The four main causes of weathering are _____, _____, _____, and _____.

Answer explanation

The four main causes of weathering are water, wind, temperature changes, and biological activity. These factors contribute to the breakdown of rocks and minerals in the environment.

The dropping of sediment by wind, water, ice, or gravity is known as _________________________.

Answer explanation

The dropping of sediment by wind, water, ice, or gravity is known as deposition. This process involves the accumulation of materials in new locations, which is essential in shaping landscapes.

A rock that has rainwater entering its cracks and then freezing will _____.

Answer explanation

When rainwater enters the cracks of a rock and freezes, it expands. This expansion exerts pressure on the rock, causing it to break apart over time. Therefore, the correct answer is that the rock will break apart.

_____ are particles of rock, minerals, or organic materials that are transported and deposited by wind, water, or ice.

Answer explanation

Sediments are the correct answer as they refer to particles of rock, minerals, or organic materials that are moved and deposited by natural forces like wind, water, or ice.

True or false: Erosion always takes a very long time to happen.

• True

• False

Answer explanation

False is correct because erosion can occur rapidly due to events like heavy rainfall or flooding, not just over long periods. Therefore, it does not always take a long time.

When wind dies down or stops blowing _________________________ happens.

Answer explanation

When wind dies down or stops blowing, deposition occurs as particles carried by the wind settle down due to the lack of movement, leading to the accumulation of sediments.

The process that involves the breaking of rocks over time due to wind is called _____.

Answer explanation

The correct term for the process of breaking down rocks over time due to wind is 'weathering'. This natural process involves the physical and chemical breakdown of rocks, leading to soil formation and landscape changes.

The process taking place when moving water is carrying away small pieces of rock is called _____.

Answer explanation

The process described is called erosion, which occurs when moving water transports small pieces of rock away from their original location, shaping the landscape over time.
