5.8 Energy & Earth Processes

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to be forced below the other, leading to earthquakes and volcanic activity.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

How can planting trees help with erosion?

Back

Planting trees along riverbanks helps slow down erosion by stabilizing the soil with their roots and reducing the speed of water flow.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process where rocks are formed, broken down, and reformed over time through processes like melting, cooling, erosion, and sedimentation.

Front

What type of rock is formed from the accumulation of sediment?

Back

Sedimentary rock is formed from the accumulation and compaction of sediment over time.

Front

True or False: The Earth is constantly changing.

Back

True. The Earth is always undergoing changes both on its surface and beneath.

Front

What is a tectonic plate?

Back

A tectonic plate is a large slab of solid rock that makes up the Earth's lithosphere and moves over the semi-fluid asthenosphere.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, two tectonic plates move away from each other, leading to the formation of new crust as magma rises to the surface.

Front

What is the difference between igneous and metamorphic rocks?

Back

Igneous rocks are formed from cooled magma or lava, while metamorphic rocks are formed from existing rocks that have been changed by heat, pressure, or chemical processes.

Front

What is sedimentation?

Back

Sedimentation is the process by which particles settle out of a fluid, forming layers of sediment that can eventually become sedimentary rock.
