Weathering and Erosion

What are the two main types of weathering?

• Mechanical and chemical weathering

• Hot and cold weathering

• Day and night weathering

• Fast and slow weathering

Explain the difference between mechanical and chemical weathering.

• Mechanical weathering involves the breakdown of rocks through chemical reactions, while chemical weathering involves the physical breakdown of rocks into smaller pieces.

• Mechanical weathering involves the physical breakdown of rocks into smaller pieces, while chemical weathering involves the breakdown of rocks through chemical reactions.

• Mechanical weathering and chemical weathering are the same process with different names.

• Mechanical weathering only occurs in cold climates, while chemical weathering only occurs in warm climates.

How does frost action contribute to weathering?

• Frost action causes rocks to become stronger and more resistant to weathering

• Frost action causes rocks to break apart due to the expansion of freezing water.

• Frost action has no impact on weathering

• Frost action causes rocks to melt and disappear

What is the rock cycle and how does it relate to weathering and erosion?

• The rock cycle is related to weathering and erosion as it shows how rocks are broken down, transported, and reformed through these processes.

• Weathering and erosion have no impact on the rock cycle

• The rock cycle only involves the formation of rocks, not their breakdown

• The rock cycle is unrelated to weathering and erosion

Describe the process of erosion and give examples of erosional features.

• Erosional features include canyons, valleys, river channels, sea cliffs, and sand dunes.

• Deserts, glaciers, and volcanoes

• Mountains, lakes, and forests

• Plains, plateaus, and islands

What are the three main types of rocks in the rock cycle?

• Igneous, sedimentary, and metamorphic rocks

• Volcanic, sedimentary, and crystalline rocks

• Molten, porous, and layered rocks

• Granite, limestone, and shale rocks

How does weathering contribute to the formation of sedimentary rocks?

• Weathering causes rocks to grow in size

• Weathering melts rocks into liquid form

• Weathering breaks down rocks into smaller pieces and creates sediment.

• Weathering has no impact on the formation of sedimentary rocks

Explain how wind and water can cause erosion.

• Wind and water can cause erosion by reducing the impact of weathering on the land.

• Wind and water can cause erosion by increasing the stability of the soil and rock.

• Wind and water can cause erosion by creating new soil and rock particles.

• Wind and water can cause erosion by carrying away soil and rock particles from one place to another.

What role does gravity play in the process of erosion?

• Gravity has no impact on erosion

• Gravity causes rocks to grow in size

• Gravity prevents erosion from occurring

• Gravity causes rocks and sediments to be transported and placed in different locations.

How does weathering and erosion impact the Earth's surface over time?

• It has a temporary effect on the Earth's surface

• It changes the Earth's surface by breaking down and transporting rocks and soil.

• It has no impact on the Earth's surface

• It causes the Earth's surface to become stronger and more stable
