How is the Earth Changing?

Theory stating that the Earth's crust is broken into plates, which are able to move along the Earth's surface.

• Theory of Continental Drift
• Theory of Plate Tectonics
• Theory of Evolution
• Theory of Relativity

NGSS.MS-ESS2-2

Plates rest on top of this layer of the Earth, which is similar to thick honey or molasses.

• Asthenosphere (Upper Mantle)

• Lithosphere (Crust/Plates)

• Inner Core

• Outer Core

NGSS.MS-ESS2-3

Convection, or cycling of hot and cold material (melted rock) occurs in this semi-liquid layer of the Earth:

• Inner Core
• Outer Core
• Mantle
• Crust

NGSS.MS-ESS2-1

Inner layer of the Earth, provides heat source. Composed of iron, nickel, and other metals. Solid Rock Layer

• Inner Core
• Outer Core
• Mantle
• Crust

Rock type that formed from magma that cools and solidifies after a volcanic eruption. Can happen above or below the surface.

• Sedimentary Rock

• Igneous Rock

• Metamorphic Rock

• Sediment

Major area in the Pacific, including Japan, which involves a large network of volcanoes and earthquakes due to plate movement and major subduction activity.

• Horn of Africa

• Gulf of Mexico

• Ring of Fire

• Hawaii

NGSS.MS-ESS2-2

Rigid upper portion of the mantle, consisting of the crust and upper mantle. This is the portion of the crust that Earth's plates are composed of.

• Asthenosphere
• Lithosphere
• Inner Core
• Outer Core

Upper layer of the Earth's mantle, below the lithosphere, where convection is thought to occur. This layer can be somewhat fluid when heated enough.

• Lithosphere
• Asthenosphere
• Inner Core
• Outer Core
