Label Your Notecards Crust Lithosphere Mantle Outer Core Inner Core Magma Lava Convection Currents

Crust

Composition: Silicon, Oxygen, and Aluminum

Types: › Continental Crust: solid & rocky outer layer› Oceanic Crust: thin & dense material

Lithosphere

Includes the Earth’s Crust & Upper Mantle

Divided into small and large tectonic plates that help move the continental and oceanic crust

Mantle

Composition: Silicon, Oxygen, and Magnesium

Thickest layer Convection currents are located here

Outer Core

Composition: Molten (liquid) Iron & Nickle

Inner Core

Composition: Solid Iron & Nickle Solid because of the pressure from the

layers above Solid inner core spins in the molten

(liquid) outer core› Creates the Earth’s Magnetic Field

Hottest layer

Convection Currents

Happens in the Middle Mantle› Has hot, dense rock that slowly flows

Movement created moves the tectonic plates in the Lithosphere

Caused by hot material, deep in the Mantle, being heated by the Core to rise then cool and sink again

Magma

Molten rock found beneath the Earth’s surface

Lava

Molten rock found on the Earth’s surface
