Hydrological Cycle (Water Cycle and Water Insecurity - Paper 1)

The pattern of river discharge over a year

Water moving vertically from soil into permeable rock

• Infiltration

• Percolation

• Interception

Raindrops prevented from falling directly onto the ground, instead hitting the leaves of a tree

What type of rainfall is this?

• Frontal

• Relief

• Convectional

The movement of water vertically through the pores of the soil

Water moving horizontally through permeable or porous rock due to gravity

• Groundwater flow

• Throughflow

The continuous transfer of water between land, atmosphere and oceans. This is a closed system.

What is the red dotted line?

The annual balance between inputs and outputs within a system

• Water balance

• Water budget

• Water building

The process through which water evaporates through the stomata in plant leaves
