Final Practice

Front

What are the steps of sedimentary rock formation?

Back

1. Weathering and erosion break down large rocks into sediment. 2. Wind and water move and help the sediment particles collect. 3. Particles are compacted and cemented into new sedimentary rock.

Front

What processes break down large boulders into smaller particles?

Back

Erosion and weathering.

Front

Why is the mantle important for Earth's plate movement?

Back

Temperature differences in the mantle create convection currents, which help to move Earth's plates.

Front

What theory supports the idea that all planets experienced many collisions resulting in impact craters?

Back

All planets likely experienced many collisions that resulted in impact craters.

Front

What type of rock is primarily found in Hawaii?

Back

Igneous rock, because Hawaii has and was formed by active volcanoes.

Front

Define sedimentary rock.

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another.

Front

What are convection currents?

Back

Convection currents are movements within a fluid caused by the uneven distribution of heat, leading to the circulation of material.

Front

What role does pressure play in rock formation?

Back

Pressure compacts sediments and contributes to the formation of sedimentary rocks.
