Test 2

Question 1

What are earthquakes

Answer 1

They are sudden tremors in the earth

Question 2

What type of plates make earthquakes and explain how

Answer 2

Passive plates. Plates that slide past each other have passive boundaries. Crust is neither created nor destroyed. These plates are locked together and then release a huge amount of energy when they slide past each other. Sliding plates cause earthquakes and fault lines.

Question 3

What happens when plates pass each other

Answer 3

There’s a built up of pressure on the fault line and when the plates get past each other this energy is released and creates an earthquake

Question 4

What is the point directly above the focus

Answer 4

Epicentre

Question 5

What are the tremors after an earthquake called

Answer 5

Aftershock

Question 6

Who measures an earthquake

Answer 6

Seismologist

Question 7

What do they use to measure an earthquake

Answer 7

Seismograph

Question 8

How do they measure it

Answer 8

Using a Richter Scale

Question 9

Damage caused

Answer 9

Loss of life
Buildings damaged
Disease
Damage to gas causing fires

Question 10

What’s an earthquake called under the sea

Answer 10

Tsunami

Question 11

Short term responses of the Japan case study

Answer 11

Tsunami warning
Run to higher ground
Other countries bring aid

Question 12

Long term responses

Answer 12

Electricity and water being restored
Homes are repaired
Roads airports are repaired

Question 13

How do fold mountains form

Answer 13

When 2 plates collide

Question 14

Alpine

Answer 14

The highest mountains in the world were formed here about 30 to 35 million years ago
Example: The Alps

Question 15

Armorican

Answer 15

This happened when the Eurasian and African plates collided about 250 million years ago
Example: MacGillycuddy’s Reeks

Question 16

Caledonian

Answer 16

Happened when the Eurasian and American plate collided about 400 million years ago

Example: Dublin mountains

Question 17

What is the case study on earthquakes called

Answer 17

Japan

Question 18

When did the earthquake case study happen

Answer 18

2011

Question 19

How do fold mountains occur

Answer 19

Plates that collide with each other have destructive plate boundaries. Here, the crust is destroyed. Huge pressure is built up and the heavier plate is pushed under the lighter plate. This is called subduction. The heavier plate melts back into the mantle. The lighter plate is lifted up, forming fold mountains. Plates that collide also cause earthquakes and volcanoes. Eg: The Andes are fold mountains that formed where the Nazca Plate is colliding with the South American Plate.
