Planet Earth

Question 1

4 Layers of earth

Answer 1

Inner core, outer core,mantle, crust

Question 2

Crust

Answer 2

Two types of crust continental and oceanic plates
3500,000,000 years old (continental) 
200, 000, 000 (oceanic)
Oceanic 6 km
Continental 55 km

Question 3

Mantle

Answer 3

2900 Km
Most mass of earth
Process convection (moving hot rocks in all directions)
Magnesium and iron

Question 4

Outer core

Answer 4

Liquid Iron and nickel
2000 Km
3000°C
Molten matter/state (rocks)
First section of core.

Question 5

Inner core

Answer 5

1350 Km
5000°C
The mass is in a liquid state of rock and has extreme pressure
It is a solid state of Iron and nickel with 4,000,000 atmospheres in its state

Question 6

Pangaea

Answer 6

Earth state 200 million years ago

Question 7

After Pangaea

Answer 7

Single landmass began to crack and divide due to the slow currents of the magma beaneth

Question 8

Today form off earth

Wengeners Continental drift evidence

Answer 8

Similar types of fossil animals and plants Found in places off to South America and Africa
East coast of South America and west coast of Africa fit together like a jigsaw puzzle
Matching rock formations and mountain chains are found in both South America and Africa

Question 9

Permian period

Answer 9

225 million years ago Pangaea formed

Question 10

Triassic period

Answer 10

200 million years ago

Question 11

Jurassic period

Answer 11

150 million years ago

Question 12

Cretaceous period

Answer 12

65 million years ago

Question 13

Present day

Answer 13

Modern and normal shape of continents

Question 14

Constructive or divergent plate Boundry

Answer 14

Mantle currents of magma pull apart the two plate creating a gap which is filled in by magma creating a mountain or volcano on mainland or in the ocean

Question 15

Destructive convergent boundary

Answer 15

As the two plates pressed against each other the oceanic plate is heavier so it is subducted the continental plate causing a Tsunami which is caused by an earthquake and interfering with the mantle which causes enough pressure to cause a volcano

Question 16

Conservative plate boundary

Answer 16

Two plates slide past each other creating a sudden release of energy causing an earthquake.

Question 17

Collision plate boundary

Answer 17

Two plates press against each other creating a fold mountain range

Question 18

Earthquake

Answer 18

Focus
Faults
Epicentre
Shockwaves or seismic waves

Question 19

Earth quake measured

Answer 19

Richter scale
Seismograph
Seismogram

Question 20

Earthquake proof building

Answer 20

Steel bars in criss-cross pattern
Shock absorbers (Rubber) and airspace and deep foundation
Near open space
Paremyd or triangular shape low top and wide bottom
Counter balance weight
Light and cheap material
Firm windows 
Flexible buliding
