S 8.3 Earth Layers and Plate Tectonics

Front

What are the main layers of the Earth?

Back

The main layers of the Earth are the Crust, Mantle, Outer Core, and Inner Core.

Front

What is the composition of the Inner Core?

Back

The Inner Core is composed mainly of solid iron and nickel.

Front

How do the Crust and Inner Core compare in terms of state of matter?

Back

Both the Crust and Inner Core are solid.

Front

What is the Mantle's role in plate tectonics?

Back

The Mantle contains convection currents that drive the movement of tectonic plates.

Front

What happens when tectonic plates collide?

Back

When tectonic plates collide, they can form mountains.

Front

What is the state of the Outer Core?

Back

The Outer Core is in a liquid state, composed of molten iron and nickel.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, including the crust and upper mantle.

Front

What are convection currents?

Back

Convection currents are movements of fluid caused by differences in temperature and density, driving plate tectonics.

Front

What is the difference between the Inner Core and Outer Core?

Back

The Inner Core is solid, while the Outer Core is liquid.

Front

What geological features can form from tectonic plate movement?

Back

Geological features such as mountains, earthquakes, and ocean trenches can form from tectonic plate movement.
