What are Tectonic Plates?

Back

Tectonic Plates are large, rigid pieces of the lithosphere that have broken up and float on the semi-fluid asthenosphere beneath.

How are Earth's surface materials recycled?

Back

Earth's surface materials are recycled through the Rock Cycle, which involves processes like erosion, sedimentation, and metamorphism.

Front

What is the Mantle?

Back

The Mantle is the thick layer of the Earth located between the crust and the core, composed of semi-solid rock that flows slowly.

Front

What is the Core of the Earth?

Back

The Core is the innermost layer of the Earth, consisting of a solid inner core and a liquid outer core, primarily made of iron and nickel.

Front

What is Erosion?

Back

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

Front

What is Sedimentation?

Back

Sedimentation is the process of settling or being deposited as sediment, often occurring in bodies of water.
