Clues to Earth’s interior

  • What’s below:

  • Deep mines & wells give clues

  • Deepest mine 3km Deepest well 12km deep

  • People cannot go down, but can send instruments

  • Temperature and pressure increase with depth

  • As you move down, temperature and pressure increase

3

Using earthquake waves

  • Studied indirectly Earthquakes release energy in the form of 3 waves

  • Some waves cannot travel through certain materials

  • Change directions when they hit certain materials

  • Use this information to infer the density and composition of materials within Earth

  • null

Earth's Layers

  • Crust

  • Thinner than other layers

  • Oceanic and Continental

  • Mantle

  • Contains more magnesium and iron

  • Denser than crust

  • Largest layer of Earth

11

12

Earth's Layers

  • Core

  • Metallic center of Earth

  • Outer core

  • Liquid because temperature is greater than pressure

  • Inner Core

  • Solid because pressure is greater than temperature

14

Multiple Choice

Is the outer core a solid or a liquid?

1

Liquid

2

Solid

15

Multiple Choice

What state of matter is the inner core?

1

Solid

2

Liquid

3

Gas

16

Multiple Choice

What is the order of the Earth's layers from outside to the inside?

1

Crust, Mantle, Inner Core, Outer Core

2

Outer Core, Inner Core, Mantle, Crust

3

Crust, Mantle, Outer Core, Inner Core

17

Multiple Choice

True or False: The crust is the thinnest layer.

1

True

2

False

18

Earth's Core & Geomagnetism

  • Earth’s spinning core creates the magnetic field

  • Earth’s magnetic field

  • Created because the inner core spins faster than the outer core

  • This is what allows compasses to work

19

Earth’s Core & Geomagnetism

  • Magnetosphere

  • Protects Earth from cosmic rays and the sun

  • Pushes some things away and traps others

20

21

Multiple Choice

Earth's liquid inner core and solid outer core is what allows us to have geomagnetism.

1

True

2

False

22

Multiple Select

What two things work together to allow compasses to work?

1

Crust

2

Mantle

3

Inner Core

4

Outer Core

23

Fill in the Blank

This is what protects Earth from cosmic rays and pushes some things away from Earth..
