Unit 3

Front

What type of rock is formed by weathering and erosion?

Back

Sedimentary rock is formed from the accumulation and compaction of sediments that result from weathering and erosion.

Front

What is chemical weathering?

Back

Chemical weathering is the process that alters the chemical composition of rocks, often leading to the formation of new minerals.

Front

Can metamorphic rocks transform into another metamorphic rock?

Back

Yes, metamorphic rocks can undergo further metamorphism and transform into different types of metamorphic rocks.

Front

In which environment does erosion by wind primarily occur?

Back

Erosion by wind primarily occurs in dry environments where there is little vegetation to hold the soil in place.

Front

How does climate affect the rate of weathering?

Back

Cool and dry climates can slow down chemical weathering, while warm and wet climates typically enhance it.

Front

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What role does water play in weathering?

Back

Water can cause both chemical and physical weathering; it can dissolve minerals and also freeze and thaw, leading to rock fragmentation.

Front

What is the difference between erosion and weathering?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials from one location to another.

Front

What are the main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

What is the process of sedimentation?

Back

Sedimentation is the process by which sediments settle out of a fluid, typically water, and accumulate in layers.
