The four main layers of the Earth's interior from top to bottom

1) Crust 2) Mantle 3) Outer Core 4) Inner Core

Earth's solid and rocky outer layer that includes land surface and the ocean floor.

Goes almost halfway through to the center of Earth.

A liquid layer composed of iron and nickel above the solid inner core.

The inner most layer, primarily solid, composed of nickel and iron.

3 types of plate boundaries

1) Transform 2) Divergent 3) Convergent

A place where two plates slip past each other, moving in opposite directions.

A place where two plates move apart, or diverge. Most of these boundaries occur at the mid-ocean ridge.

Convergent Boundaries

The place where two plates come together or converge. When two plates converge, the result is a collision.

Alfred Wegener's supercontinent, meaning "all lands". Wegener's siad that all the continents had once been joined together in a single landmass and have since drifted apart.

Build up the Earth's surface (examples: mountains and volcanoes).

Slowly wear away the surface (examples: wind, erosion, and gravity).

Theory of Plate Tectonics

The theory that states that the plates of the Earth are in constant motion.

Two metals that make up the inner and outer core.

Sub-layer of the mantle that means "Stone" in Greek.

Sub-layer of the manthle that means "weak" in Greek.

3 forms of evidence that Alfred Wegener used to support his theory of plate tectonics

1) fossils 2) landforms 3) climate

Two layers that make up the Earth's crust

1) Continental Crust 2) Oceanic Crust

Question	Answer
The four main layers of the Earth's interior from top to bottom	1) Crust 2) Mantle 3) Outer Core 4) Inner Core
Crust	Earth's solid and rocky outer layer that includes land surface and the ocean floor.
Mantle	Goes almost halfway through to the center of Earth.
Outer Core	A liquid layer composed of iron and nickel above the solid inner core.
Inner Core	The inner most layer, primarily solid, composed of nickel and iron.
3 types of plate boundaries	1) Transform 2) Divergent 3) Convergent
Transform Boundaries	A place where two plates slip past each other, moving in opposite directions.
Divergent Boundaries	A place where two plates move apart, or diverge. Most of these boundaries occur at the mid-ocean ridge.
Convergent Boundaries	The place where two plates come together or converge. When two plates converge, the result is a collision.
Pangaea	Alfred Wegener's supercontinent, meaning "all lands". Wegener's siad that all the continents had once been joined together in a single landmass and have since drifted apart.
Two types of forces that help shape the Earth's surface	1) Constructive 2) Destructive
Constructive Force	Build up the Earth's surface (examples: mountains and volcanoes).
Destructive Force	Slowly wear away the surface (examples: wind, erosion, and gravity).
Theory of Plate Tectonics	The theory that states that the plates of the Earth are in constant motion.
Iron and Nickel	Two metals that make up the inner and outer core.
Lithosphere	Sub-layer of the mantle that means "Stone" in Greek.
Asthenosphere	Sub-layer of the manthle that means "weak" in Greek.
3 forms of evidence that Alfred Wegener used to support his theory of plate tectonics	1) fossils 2) landforms 3) climate
Two layers that make up the Earth's crust	1) Continental Crust 2) Oceanic Crust
