1.0 - Perception Of Water

Question 1

Storage

Answer 1

Where water is held

Question 2

Processes

Answer 2

The physical mechanisms that drive fluxes

Question 3

Fluxes

Answer 3

The ways that water changes state i.e. moves around the world.

Question 4

Open Water System

Answer 4

Both inputs and outputs e.g. drainage basin

Question 5

Closed Water System

Answer 5

Water has no exit e.g. hydrological cycle water goes (solid ice, water vapour, liquid flow, back to ice).

Question 6

Water Budgets

Answer 6

Show the balance between water storage and water fluxes. Most water is inaccessible, and some stores can be replenished whilst others can’t

Question 7

Causes Of Change To Water Budget

Answer 7

Human Activity - Extraction, Reservoirs, Drinking
Climate Change - Evaporation, Precipitation, Melting

Question 8

Rainfall In The Mid-Latitude

Answer 8

Cold polar air meets warm tropical air from the south, the warm air rises and it cools and condenses to clouds which causes rain e.g. frontal rainfall/mid-latitude depressions.

Question 9

Rainfall At The Equator

Answer 9

The sun is directly overhead the equator, heating the land and the water/air, creating lower density, causing air to rise, then cool, cloud and condense i.e. convectional rainfall.

Question 10

Rainfall At The Tropics

Answer 10

Hadley cell causes the air to sink at the tropics, making air pressure high and less clouds form meaning there’s less rain making the ground temperature high, and then no rainfall to cool it down.

Question 11

Hadley Cell

Answer 11

Warm, moist air rises, to 30 deg N and S of the equator, where air becomes cool and dry and begins to sink as it becomes more dense. It sinks back towards the equator where the air will get warm again and the cycle repeats. The circular motion of these clouds are called trade winds.
