Extreme weather

Question 1

What do you call a rock that lets water seep through?

Answer 1

Permeable

Question 2

What do you call leaves that catch rainwater?

Answer 2

Interception

Question 3

What comes after surface runoff?

Answer 3

Infiltration - when the rain soaks into the ground.

Question 4

Give the definition of through flow

Answer 4

When the rain water flows sideways through the soil.

Question 5

What is the opposite word for permeable?

Answer 5

Impermeable

Question 7

What is the definition of impermeable?

Answer 7

When the rock will not let water through

Question 8

What is the meaning of groundwater flow?

Answer 8

When the groundwater flows along slowly

Question 9

What is the order of the rain’s water journey to the river?

Answer 9

1) interception
2) surface runoff
3) infiltration
4) through flow
5) groundwater
6) groundwater flow

Question 10

Definition of groundwater

Answer 10

When some of the rain water soaks right down and fills up pores and cracks in the rock

Question 11

What is surface runoff?

Answer 11

When the ground is hard, or very wet, rainwater just runs along it.

Question 12

Convection rainfall

Answer 12

Sun heats the ground
Warm air rises (convection currents)
The air cools and condenses which cause rainfall

Question 13

Relief rainfall

Answer 13

Wind moves the air
When it meets hills or mountains the air is forced to rise up
As it rises it cools

Question 14

Frontal rainfall

Answer 14

Big air masses ( large body of air) move around the earth
Warm air meets cold air
Warm air forced to rise up
This causes condensation and rain

Question 15

Evaporation

Answer 15

Water changes from liquid to gas because it is heated up

Question 16

Condensation

Answer 16

Water changes from a gas to a liquid because it has cooled down

Question 17

Transpiration

Answer 17

Evaporation of water from leaves and plants

Question 18

What causes a flood

Answer 18

• Short period of heavy rain ( too much water)
• Raining for a long period (too much water)
• Melting snow ( adds volume to the water. The water would melt quickly and it would have nowhere to go)
• Deforestation ( no interception)
• Urbanisation ( building are impermeable so the surface run-off on buildings. Not many fields because of buildings so no infiltration
• Steep land

Question 19

Effects of a flood

Answer 19

Business have to close 
Deaths/drowning
Damage to buildings
High cost for repairing damages
Crops may be damaged- food shortages 
Peoples homes are flooded
