Question 1

How is heat redistributed through the air?

Answer 1

Hot air rises to form low pressure. Cold air sinks to form high pressure

Question 2

How is heat redistributed through the ocean?

Answer 2

Cold water is salty and dense so it sinks near the poles. This drags warm water from the equator witch releases heat into the air

Question 3

Explain stage 1 of tectonic plate movement

Answer 3

Radioactive decay comes from the earths inner core causing heat

Question 4

Explain stage 2 of tectonic plate movement

Answer 4

The heat rises into the mantle

Question 5

Explain stage 3 of tectonic plate movement

Answer 5

This causes the magma to plume (rise) upwards as it’s less dense

Question 6

What is a plate boundary

Answer 6

Where 2 plates meet

Question 7

What is a divergent boundary

Answer 7

Where plates move apart

Question 8

What does a divergent boundary form

Answer 8

Shield volcanoes

Question 9

What is a convergent boundary

Answer 9

Where plates collide

Question 10

What happens at a divergent plate boundary

Answer 10

Basalt magma rises through the gap

Question 11

What happens at a convergent boundary

Answer 11

Oceanic plate subducts, as it sinks it melts, plumes rise up through the continental crust, erupting

Question 12

What forms at convergent boundaries

Answer 12

Strato volcanoes

Question 13

What happens at conservative boundaries

Answer 13

They slide past each other

Question 14

What do conservative boundaries form

Answer 14

Earthquakes. They can be very destructive as their epicentres are often shallow

Question 15

What do sunspots cause

Answer 15

Long term climate change over hundreds of years

Question 16

What do orbital changes effect

Answer 16

The amount of solar radiation radiation the earth receives every 100,000 years

Question 17

What do orbital changes cause

Answer 17

Ice ages

Question 18

Why can volcanic activity do

Answer 18

Release global temperatures by up to 0.5C

Question 19
