Plate Tectonics/Earth's Layers Review

Front

What are Earth's tectonic plates?

Back

Earth's tectonic plates are large, rigid pieces of the Earth's lithosphere that are constantly moving and changing the face of the Earth.

Front

What geological feature is formed when two continental plates converge?

Back

Folded Mountains are formed when two continental plates converge (collide).

Front

What is the asthenosphere?

Back

The asthenosphere is a layer of the Earth located below the lithosphere, characterized by its semi-fluid nature, allowing tectonic plates to move.

Front

What is the correct order of Earth's layers from the surface?

Back

The correct order of Earth's layers from the surface is: crust, mantle, outer core, inner core.

Front

What causes the movement of Earth's tectonic plates?

Back

The movement of Earth's tectonic plates is primarily caused by convection currents in the mantle.

Front

Define lithosphere.

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

Front

What is the outer core?

Back

The outer core is a liquid layer of the Earth located beneath the mantle and above the inner core, composed mainly of iron and nickel.

Front

What is the inner core?

Back

The inner core is the solid, innermost layer of the Earth, composed primarily of iron and nickel, and is extremely hot.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate moves under another, leading to geological features like trenches and volcanic activity.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by the upwelling of magma at divergent tectonic plate boundaries.
