Mrs S- Natrual Hazards, Tectonic Hazard/Plate, Haiti,New Zealand.

Question 1

Define Natural Hazards

Answer 1

A natural event that threatens people or has the potential to cause damage, destruction and death

Question 2

Give examples of tectonic hazards

Answer 2

Earthquakes, tsunamis, volcanoes

Question 3

Give examples of atmospheric hazards

Answer 3

Tropical storms, climate change, drought, freezing conditions, hurricanes/cyclones, heatwaves, low pressure storms, blizzards, flooding, frost, tornadoes

Question 4

Give samples of geomorphology all hazards

Answer 4

Avalanches, landslides, flooding

Question 5

Examples of biological hazards

Answer 5

Forest fires

Question 6

How are tsunamis category linked to tectonic hazards

Answer 6

Tsunamis are a tectonic hazard doomed by earthquakes and volcanoes, however they can be caused by landslides

Question 7

Can some natural hazard be influenced by humans and why

Answer 7

Yes because human influences climate change and forest fires.

Question 8

Has global warming increased or deacresed and how

Answer 8

Global warming has increased by frequency and magnitude of natural hazards
Eg flood, forest fires, droughts,hurricanes

Question 9

Has deforestation increased or deacresed

Answer 9

Increases

Eg floods, landslide

Question 10

Has urbanisation increased or deacresed

Answer 10

Increased

Eg flooding

Question 11

Is there a increase or decrease of population

Answer 11

Increase

Question 12

Which location are more prone to natural hazard

Answer 12

Japan

Eg cyclones

Question 13

Is LIC’s more at risk and why

Answer 13

Yes because peer economies for preparation and protection

Question 14

Where do natural hazards occur

Answer 14

Earthquakes: Haiti, Chile
Volcanic eruption: Iceland,Indonesia ,
Flooding: China
Avalanches: Pakistan

Question 15

Define crust

Answer 15

The outer most layer of the earth 5km-90km

Question 16

Define Mantle

Answer 16

A layer of rock between the core and the crust made of molten rock includes magma

Question 17

Is the outer core solid or liquid

Answer 17

Liquid

Question 18

Is the inner core dense and is it a solid or a liquid

Answer 18

It is very dense and a solid rock

Question 19

Learn the table

Answer 19

Learn the table in book on post it note

Question 20

Learn the plate boundaries

Answer 20

On the poster

Question 21

What makes tectonic plate move

Answer 21

Convection current

Question 22

What is the core temperature around

Answer 22

6000 degrees

Question 23

What does the core temperature cause

Answer 23

The molten rock magma to rise in the mantle and sinks towards the core when it cools

Question 24

What do the current flow carry in the mantle

Answer 24

The plate margins

Question 25

What is a slab pull theory

Answer 25

At the constructive margins ocean ridges from above the ocean floor. Beneath it the mantle melts (molten magma rises as the plates move apart and cools down from a new plate material) As it cools it slides down the ridge making the plates to move away (ridge push)

Question 26

What does a destructive margin do

Answer 26

The plate gets denser and sinks back into the mantle under the influence of gravity which pulls the plate along with it (slab pull)
