Coastal flooding

Question 6

What is biological flooding

Answer 6

Diseases
Global warming
The involve living organisms

Question 7

Where are tropical storms formed

Answer 7

They are formed over warm oceans (above 27*c)

Question 8

What factors affect hazard risk

Answer 8

Global warming
Deforestation
Urbanisation

Question 9

What is the earths structure

Answer 9

The earth structure is divided into layers. The centre is called the core which is extremely hit and under a lot of pressure. The inner core is solid and the outer core is liquid. The mantle surrounds the core it is made out of a solid material that can flow very slowly. Asthenosphere which can be deform like plastic. The outmost later is called the crust which is very thin compared to the mantle and the core

Question 10

What are he different types of crust

Answer 10

Continental crust and the oceanic crust which differ in chemical composition thickness and density

Question 11

What are the three plate margins

Answer 11

Constructive destructive and conservative

Question 12

How do tectonic plates move

Answer 12

The magma rises to the mantle and sinks towards the core when it cools. The currents flow beneath the lithosphere building up pressure which carries the plates with them

Question 13

Where are earthquakes and volcanoes located

Answer 13

They are not randomly distributed. There pattern matches when plate margins are located earthquakes are found of all three types of plate margins whereas volcanoes are only found of to constructive and destructive

Question 14

Ho do plates move at constructive margins

Answer 14

They move when tectonic plates move apart from each other

Question 15

How do plates move at destructive margins

Answer 15

They occur when tectonic plates move towards each other and collide

Question 16

How do conservative plate margins move

Answer 16

It occurs when tectonic plates move parallel to each other

Question 17

Why do people like in hazardous areas

Answer 17

Geothermal energy 
Farming 
Mining 
Tourist 
Family, friends and feelings

Question 18
