@Fonomanu & 'Unaloto ko e tali eni ki hoomo fehui on: Explain two factors that affect the global distribution of fresh water resources. Two factors: climate and geology. i) climate Low levels of rainfall and high temperatures lead to water deficit. When rainfall is low, there is less water available. When temperatures are high water evaporated and so there is less water to use. Water surpluses are common where is high and temperatures are low. ii) geology Rainfall flows down to the rocks beneath the ground Some rocks are permeable and allow water to flow through them. Permeable rocks can lead to less surface water For example limestone landscapes often have dry rivers- the rivers only exist when rain fall have just fallen Permeable rocks firm aquifers, which mean they are stores of water. 70 oer cent of the water supply in the South to East of England come from the chalk aquifer beneath the surface. When rocks are imperable. These rocks do not hold water, but they can trap it in the la above.

Define non renewable resources: Non renewable resources are resources that you use only once. eg. Kerosene, gas for cooking , firewood, petrol.

Lahars can happen with or without volcanic eruption. Lahars are masses of rock , mud and water that travel rapidly downstream under the action of gravity Example: there were are lot of lahars moving during the Tonga Hunga eruption. The stones, pebbles, ashes etc that you had to clean up after the eruption.
