Layers of Earth 🌍

Question 1

Physical Layers of Earth

Answer 1

The lithosphere, asthenosphere, mesosphere, outer core and inner core.

Question 2

Chemical Layers of Earth

Answer 2

Crust, Mantle, Core

Question 3

Upper Mantle

Answer 3

Lithosphere, Asthenosphere,

Question 4

Lower Mantle

Answer 4

Mesosphere

Question 5

Core

Answer 5

Outer and inner core

Question 6

Seismic waves are?

Answer 6

Waves of energy that travel through the Earth’s layers.

Question 7

The seismic waves can be read how?

Answer 7

These waves can be read by seismometers and show up as wavy lines.

Question 8

What is telling us the size of the lines?

Answer 8

The size of the line can tell us what type of material it moved through.

Question 9

What is the pressure?

Answer 9

The amount of force pushing on a certain area.

Question 10

Crust

Answer 10

Earth’s outermost layer of solid rock that includes land and ocean floor

Question 11

Lithosphere

Answer 11

Rigid upper most part of the mantle and the crust

Question 12

Lithosphere

Answer 12

Solid and broken up into plates.
These plates are constantly moving and slowly moving away or bumping in to one another.

Question 13

Asthenosphere

Answer 13

Consists of partly molten rock.
It is the part of the upper mantle that flows easily.
This movement is called plasticity.
Convection Currents occur here.

Question 14

Convection currents

Answer 14

Convection is responsible for the movement of the plates that make up the Lithosphere.

Question 15

Mesosphere

Answer 15

Also called Lower Mantle
Is the largest part of the mantle.

Question 16

Mesosphere

Answer 16

It is more rigid than asthenosphere. .
Thicker than the UM & Asthenosphere

Question 17

Core

Answer 17

Innermost part of the earth consisting of 2 parts
Made up of mostly iron and nickel

Question 18

Outer core

Answer 18

Thick liquid, molten material of Iron and Nickel.
These liquid metals create Earth’s Magnetic Field

Question 19

Earth’s Magnetic Field

Answer 19

Moving molten Nickel and Iron from our outer core creates magnetism that surrounds the Earth in an invisible field.

Question 20

Earth’s Magnetic Field

Answer 20

Our magnetic field blocks solar radiation from entering our Earth.
Without it protecting us, there would be no water or life on Earth.

Question 21

Aurora Borealis

Answer 21

When solar radiation enters our magnetic field at the North and South poles, it creates an amazing light display.

Question 22

Inner Core

Answer 22

The inner core is a dense ball of solid metal
Made of iron
