Unit 2 Earths Layers and Tectonic Plates Vocabulary quiz

Crust

• The solid, plastic layer of the mantle beneath the lithosphere; Made of mantle rock that flows very slowly which allows tectonic plates to move on top of it
• The layer of rock between Earth's crust and core
• The strong lower part of the mantle between the asthenosphere and the outer core.
• The thin and solid outermost layer of the earth above the mantle

Mantle

• The thin and solid outermost layer of the earth above the mantle
• The layer of rock between Earth's crust and core
• The solid, plastic layer of the mantle beneath the lithosphere; Made of mantle rock that flows very slowly which allows tectonic plates to move on top of it
• The strong lower part of the mantle between the asthenosphere and the outer core.

Convection

• Stress that occurs when forces act to stretch an object
• The layer of rock between Earth's crust and core
• The bending, tilting and breaking of Earth's crust; The change of the shape of rock due to stress.
• The movement of matter due to differences in density caused by temperature variations

Core

• The thin and solid outermost layer of the earth above the mantle
• The central part of Earth below the mantle
• The solid, plastic layer of the mantle beneath the lithosphere; Made of mantle rock that flows very slowly which allows tectonic plates to move on top of it
• The layer of rock between Earth's crust and core

Lithosphere

• The thin and solid outermost layer of the earth above the mantle
• The solid, plastic layer of the mantle beneath the lithosphere; Made of mantle rock that flows very slowly which allows tectonic plates to move on top of it
• The solid, outermost layer of the earth that consists of the crust and rigid upper part of the mantle.
• The layer of rock between Earth's crust and core

Asthenosphere

• The solid, plastic layer of the mantle beneath the lithosphere; Made of mantle rock that flows very slowly which allows tectonic plates to move on top of it
• The layer of rock between Earth's crust and core
• The solid, outermost layer of the earth that consists of the crust and rigid upper part of the mantle.
• The thin and solid outermost layer of the earth above the mantle

Mesosphere

• The solid, outermost layer of the earth that consists of the crust and rigid upper part of the mantle.
• The strong lower part of the mantle between the asthenosphere and the outer core.
• The solid, plastic layer of the mantle beneath the lithosphere; Made of mantle rock that flows very slowly which allows tectonic plates to move on top of it
• The layer of rock between Earth's crust and core

Pangaea

• The boundary between tectonic plates that are colliding
• The theory that explains how large pieces o the lithosphere, called plates, move and change shape.
• The layer of rock between Earth's crust and core
• The supercontinent that formed 300 million years ago and that began to break up 200 million years ag

Sea-floor spreading

• The boundary between tectonic plates that are colliding
• The process by which new oceanic lithosphere sea floor forms when magma rises to Earth's surface at mid-ocean ridges and solidifies as older, existing sea floor moves away form the ridge
• The theory that explains how large pieces o the lithosphere, called plates, move and change shape.
• The layer of rock between Earth's crust and core

Convergent Boundary

• The boundary between tectonic plates that are colliding
• The theory that explains how large pieces o the lithosphere, called plates, move and change shape.
• The boundary between 2 tectonic plates moving AWAY from eachother.
• The boundary between tectonic plates that are sliding past each other horizontally
