Convection Currents

Movement in the asthenosphere, hot mantle go ↑ cool mantle ↓

Volume

How much space an object takes up

Density

Amount of matter in a certain amount of space

Magma

Melted rock inside the EarthMagnetic

Magnetic

The outer core creates this kind of field

Basalt

The oceanic crust is most made up of this rock

Iron

The core is mostly made up of nickel and this metal

Mass

How much matter is in an object

Lithosphere

Crust plus upper layer of mantle

Asthenosphere

Where convection currents happen

Continental

The earth's land is made up of this crust

Solar winds

The magnetic field protects earth from these

Granite

The continental crust is mostly made of this rock

Pressure

The inner core is solid because of this

C- Outer core
D- Inner core

D

Which statement is true?
A- The crust is thicker under the continental crust than the oceanic crust
B- The crust is the thickest layer of the Earth
C- The mantle creates a magnetic field to protect earth from solar winds

A

Label the layers of the earth

From outermost to innermost: Crust, Mantle, Outer core, Inner core

Name the state and Composition of the crust

The state is solid and composition is basalt, granite

Name the state and composition of the mantle

State is mostly solid but soft rock and composition is rock and magma

Name the state and composition of the outer core

The state is liquid and composition is Iron, Nickel, Sulphur, and oxygen

Name the state and composition of the inner core

The state is solid and composition is Iron and nickel
