Question 12

What type of CLIMATE does the British Isles have?

Answer 12

The British Isles has a TEMPERATE climate.

This means that it is not too hot, not too cold, not too dry and not too wet.

Question 15

Why is there more RAINFALL in the West of the UK?

Answer 15

Many of the MOUNTAIN ranges in the British Isles occur in the West.

The moist warm air from the West hits the mountains and forces it to rise up and form clouds. It then rains as the air moves to the East.

The West is therefore more likely to experience rainfall.

Question 19

What causes FLOODING?

Answer 19

1. A river is like a big drain.
2. The rain that falls on the land around a river, drains into it.
3. The water is carried out to the sea by the river.
4. If the river fills up too quickly, the river bursts its banks and overflows onto the land - this is a flood.

Question 20

What makes FLOODING more likely?

Answer 20

Things that cause floods:

1. If rainfall is particularly heavy and prolonged.
2. If the land around the river doesn’t have enough trees to soak up the rain.
3. If the land is already very wet (saturated) it cannot soak up anymore rain.
4. If the river is full of sand, mud or rubbish, it may cause blockage.

Flooding Happens To Saturated Blockages.

Question 21

What is CLIMATE CHANGE?

Answer 21

• Climate change is a natural occurring phenomenon and has been happening to the Earth over the last 500,000 years.
• The change is caused by Milankovitch Cycles

Question 22

How do humans enhance the GREENHOUSE EFFECT?

Answer 22

The human race enhances the Greenhouse effect by producing more Greenhouse gases like:

• CO2
• Methane
• Water Vapour
• Nitrous Oxide

These gases are produced by factories, cars, cows and cutting down trees.

Question 23

Why are some scientists concerned with CLIMATE CHANGE?
