Question 10

Explain infiltration

Answer 10

When water enters the soil

Question 11

Explain saturated ground

Answer 11

When the ground is saturated if is full it cannot hold anymore water

Question 12

Explain surface run-off

Answer 12

When water flows over the ground as it cannot infiltrate because ground is saturated

Question 13

Explain impermeable surfaces

Answer 13

Means water can’t pass through this increases surface run-off as water cannot infiltrate through the ground.

Question 14

Explain lack of interception

Answer 14

Vegetation interrupts the water meeting the ground so the lack of it means if will meet the ground quicker and can increase surface run- off

Question 15

Answer 15

The sun heats up the ocean to 27 degrees

Question 16

Name the second step of formation of a hurricane

Answer 16
