Unit 3 Lesson 1 Earth's Layers

What is the definition of CRUST?

• The thin and solid outermost compositional layer of Earth.

• The putty-like, physical layer of the mantle, on which the tectonic plates move.

• The theory that Earth’s outer layer is made up of large, moving pieces.

• The central part of Earth below the mantle, is very dense.

What is the definition of MANTLE?

• The thin and solid outermost layer of Earth.

• The compositional layer of rock between the Earth's crust and core.

• The process by which one plate moves beneath another plate as a result of tectonic forces.

• .The central part of Earth below the mantle, is very dense.

What is the definition of CORE?

• The thin and solid outermost layer of Earth.

• The strong, lower part of the mantle, the physical layer between the asthenosphere and the outer core.

• Where two tectonic plates meet.

• The central part of Earth below the mantle, is very dense.

What is the definition of LITHOSPHERE?

• The solid, outermost physical layer of Earth, that consists of the crust and the rigid upper part of the mantle.

• The putty-like, physical layer of the mantle, on which the tectonic plates move.

• The strong, lower part of the mantle, the physical layer between the asthenosphere and the outer core.

• The central part of Earth below the mantle, is very dense.

What is the definition of ASTHENOSPHERE?

• The solid, outermost physical layer of Earth, that consists of the crust and the rigid upper part of the mantle.

• The putty-like, physical layer of the mantle, on which the tectonic plates move.

• The strong, lower part of the mantle, the physical layer between the asthenosphere and the outer core.

• The central part of Earth below the mantle, is very dense.

What is the definition of MESOSPHERE?

• The solid, outermost physical layer of Earth, that consists of the crust and the rigid upper part of the mantle.

• The putty-like, physical layer of the mantle, on which the tectonic plates move.

• The strong, lower part of the mantle, the physical layer between the asthenosphere and the outer core.

• The central part of Earth below the mantle, is very dense.

What is the definition of SEISMIC WAVE?

• The theory that Earth’s outer layer is made up of large, moving pieces.

• A wave of energy released by an earthquake, that travels through the Earth and away from an earthquake in all directions.

• The point on Earth's surface directly above an earthquake's starting point, or focus.

• An instrument that measures and records the details of an earthquake.

What is the definition of CONVECTION CURRENT?

• A wave of energy released by an earthquake, that travels through the Earth and away from an earthquake in all directions.

• The process by which new oceanic lithosphere (sea floor) forms when magma rises to Earth's surface; older, existing sea floor moves away from the ridge.

• The process by which one plate moves beneath another plate as a result of tectonic forces.

• Any movement of matter that results from differences in density; may be vertical, circular, or cyclical.
