Question 4

Transpiration means?

Answer 4

Plants giving off water from their leaves

Question 5

Groundwater means?

Answer 5

Water that has sunk into the rocks below

Question 6

Hydraulic action process involves?

Answer 6

This process involves the force of the water against the bed and banks

Question 7

Abrasion process involves?

Answer 7

This is the process by which the bed and banks are worn down by the rivers load. The river throws these particles against the bed and banks, sometimes at high velocity (like sandpaper)

Question 8

Adritition process involves?

Answer 8

Material ( the load) carried by the river bump into each other and are so smoothed and broken down into smaller particles

Question 9

Corrosion process involves?

Answer 9

This is the chemical action of the river water. The acids in the water slowly dissolve the bed and banks

Question 10

Traction involves?

Answer 10

Boulders and pebbles are rolled along the river bed at high discharge (in a flood)

Question 11

Saltation involves?

Answer 11

Sand sized particles are carried along within the water even at low discharges ( a small stream)

Question 12

Solution involves?

Answer 12

Some minerals dissolve in water such as calcium carbonate. This requires very little energy
