earth Layer

Question 1

Lithosphere

Answer 1

The rigid part of the earth- also is a solid, and is 1,800 miles deep.

Made out of rocks and soil,

300-500°

Question 2

Mantle

Answer 2

thick layer inside the Earth, below the crust. Most of the mantle is solid rock, although the upper part is molten rock called magma.

100km-2900km deep

500-900°.

Question 3

Outercore

Answer 3

Is the outer part of the core. It is a liquid.

And is 2900- 5100km deep

4000-5000°

Question 4

Inner core

Answer 4

It’s the inner part of the core and is much hotter than a lot of the others. And is 6000° it is made out of iron knickle

5100-6378km deep

Almost as hot as the sun.

Question 5

Core

Answer 5

Is the centre of the earth. And is the hottest part

Question 6

Seismic waves

Answer 6

waves of energy that travel through the Earth’s crust, caused by earthquakes.

Question 7

Continental drift

Answer 7

movement of the plates of the Earth’s crust in relation to each other.

Question 8

Pangaea

Answer 8

a super-continent that existed about 225 million years ago. All of the landmasses that existed at this time were joined together to form this super-continent. (Happened by the plates)

Question 9

Panthalassa

Answer 9

The vast sea surrounding the super-continent of Pangaea

Question 10

Plate tectonics

Answer 10

the theory concerning the movement of the continental plates.

Question 11

Convection current

Answer 11

circular movement that occurs when warmer, less dense fluid particles rise and cooler, denser fluid particles sink

Question 12

Continental crust

Answer 12

the plates of the Earth’s crust that make up the land

Question 13

Continental crust

Answer 13

the plates of the Earth’s crust that make up the land

Question 14

Oceanic crust

Answer 14

one of the types of crust that makes up the Earth’s outer layer.

Oceanic crust is thinner than continental crust.

and made up basalt which is dense and heavy

Question 15

Boundaries

Answer 15

The edges of tectonic plates

Question 16

Subduction

Answer 16

process in which two tectonic plates push against each other.

and oceanic crust sinks below the less dense continental crust

Question 17

Destructive plate boundaries

Answer 17

A convergent boundary where 2 plates collide

Question 18

Constructive plate boundaries

Answer 18

plate that creates new land from cooling magma

Question 19

Ocean ridges

Answer 19

An area where tectonic plates move apart
