Unit 5 Review- 2 answers

Front

What process leads to the formation of sedimentary rocks from pre-existing rocks?

Back

Weathering and erosion are the processes that break down rocks into smaller particles, which can then accumulate and form sedimentary rocks.

Front

What process transforms sedimentary rock into metamorphic rock?

Back

Heat and pressure are the key factors that change sedimentary rock into metamorphic rock, altering its structure and mineral composition.

Front

What is the main agent of erosion that shapes landscapes by transporting sediment?

Back

Water is the primary agent of erosion, as it can carry sediment away from one location and deposit it in another, shaping the landscape.

Front

What is the primary reason for the formation of mountains?

Back

Mountains are primarily formed by the collision of tectonic plates, which can cause the Earth's crust to fold and uplift.

Front

Which type of rock is formed from the cooling and solidification of magma or lava?

Back

Igneous rock is formed when magma cools and solidifies beneath the Earth's surface or when lava cools on the surface.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by water, wind, or ice.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes and mountain formation.

Front

What is sediment?

Back

Sediment consists of small particles of rock, minerals, and organic material that are transported and deposited by natural forces.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks through heat, pressure, and chemical processes.
