Earth's Layers and Plate Tectonics Flashcard

Front

Which layer of the Earth is responsible for tectonic plate movement?

Back

Mantle

Front

Increasing the temperature of a material will cause its density to increase or decrease?

Back

Decrease

Front

The outermost layer consisting of the Earth's crust and part of the upper mantle is called what?

Back

Lithosphere

Front

Which Layer of the Earth is the thinnest?

Back

Crust

Front

What layer is 1?

Back

Inner Core

Front

What is the composition of the Earth's crust?

Back

The Earth's crust is primarily composed of silicate rocks, including granite and basalt.

Front

What is the difference between the lithosphere and asthenosphere?

Back

The lithosphere is the rigid outer layer of the Earth, while the asthenosphere is a semi-fluid layer beneath it that allows for tectonic movement.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is the role of the outer core in Earth's geology?

Back

The outer core is responsible for generating Earth's magnetic field through the movement of molten iron.
