Question 5

What happens at plate margins

Answer 5

Constructive
Destructive
Conservative

Question 6

Plate margin eg

Answer 6

Iceland is a country in the north Atlantic Ocean it is situated on the mid Atlantic Ridge a plate margin where two plates are moving away from each other, there are several active volcanoes in Iceland.

Question 7

Constructive

Answer 7

Where two plate move apart
Magma is forcing its way to surface as it breaks through the overlying crust it causes earthquakes
The magma at constructive margins very hot and fluid lava erupting from the volcano will flow along way before calling this results in a typically broad and flat shield volcano

Question 8

Destructive

Answer 8

Where two plates are moving towards one another
Friction between these plates can cause strong earthquakes and as the oceanic plate moves downwards and melts which creates magma which breaks through to the surface to form a volcano.
The two plates collide and become crumpled and uplifted which form mountains

Question 9

Conservative

Answer 9

Where two plates are sliding alongside each other.

Friction between the plates cause earthquakes such as the San Andreas fault in California

Question 10

Immediate responses

Answer 10

Search and rescue and keeping survivors alive by providing medical care, food, water and shelter

Question 11

Long-term response

Answer 11

Rebuilding and reconstruction, with the aim of returning peoples lives back to normal and reducing future risk

Question 12

Tropical storm

Answer 12

That huge storm that develops in the tropics they are very powerful and can cause huge damage

Question 13

How do tropical storms form

Answer 13

Firstly a strong upward movement of air draws water vapour from the ocean surface
Then this evaporated air cools as it rises and condenses to form thunderstorm clouds
Then as the air condenses it really does heat which powers the storm
Then several small thunderstorms joined together to form a giant spinning storm
This develops and I at its centre where air descends rapidly
