Extra stuff (but still important)
Rock
A naturally occurring solid mixture of one or more minerals or organic matter.
Inner core
Solid, dense center of the Earth. Made of iron.
Mantle
The layer of the earth between the crust and the core. The Largest Layer of the earth. Makes up 2/3 of Earth’s Mass. Convection currents can be found here.
Crust
The Outer layer of the Earth. Earth’s thinnest layer. Composed aluminum, silicon, oxygen
Lava
Liquid magma that reaches the surface; also the rock formed when liquid lava hardens.
Outer core
A layer of molten iron and nickel that surrounds the inner core of Earth. Earth’s only completely liquid layer.
Magma
Molten rock in the earth's Mantle.
Oceanic crust
Thin, more dense than continental crust, sub-ducting crust
Earth layers
Crust, Mantle, Outer Core, Inner Core
Magnetic field
A field that surrounds the Earth because of earth's convection currents in earth's liquid iron core.
The movement of a fluid, caused by differences in temperature, heated fluid rises, and cooler fluid sinks.
Continental crust
Thicker, less dense crust
Seismic waves
Waves (earthquakes) that help us study the inner layers of Earth.
Tectonic plate (Plate Tectonics)
Sections of the Earth's crust that move due to convection currents.A piece of the lithosphere that moves around on top of the Asthenosphere
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.
Lithosphere
The solid, outer layer of the earth that consists of the crust and the rigid upper part of the upper mantle.
