What are the six stages of the water cycle?
Evaporation, condensation, precipitation, run off, transpiration, infiltration

What is a catchment?
(Answer: An area of land where all water drains into a single river, lake, or ocean.)
100
True or False: The Earth's water is evenly distributed.
(Answer: False—some places have lots of rain, others very little.)

What does "water scarcity" mean?
(Answer: When there is not enough freshwater available to meet people's needs.)
200
What happens to rainwater after it falls to the ground?
(Answer: It may soak into the ground (infiltration), flow into rivers/lakes (runoff), or evaporate again.)
200
Why is it important to keep catchments clean?
(Answer: Polluted water affects people, animals, and ecosystems.)
200
What percentage of the Earth's water is freshwater?
(Answer: About 3%.)
200
What are 3 major sectors that use water all around the world?
Domestic, agriculture, industry
300
Explain how transpiration works.
(Answer: Plants absorb water from the soil and release it as water vapor from their leaves.)
300
What are 2 ways humans manage catchments to protect water quality?
(Answer: Planting trees, settling ponds, reducing pollution, preventing erosion.)
300
Why do some places, like the Amazon Rainforest, receive a lot of rainfall while deserts get very little?
(Answer: Climate patterns—rainforests are near the equator where warm air rises, deserts are in dry zones where air sinks.)
300
What are 3 economic impacts of water scarcity?
(Answer: Less water for agriculture leads to food shortages and higher prices, farmers lose their farms.)
400
Why is the water cycle important?
(Answer: It moves water around the Earth, making fresh water available for living things.)
400
How does Australia's rainfall affect where most people live?
(Answer: Most people live in the eastern and southern coastal areas because these places get more rainfall. The central and western parts of Australia are very dry, so fewer people live there.)
400
What is the cryosphere, and why is it important for the Earth's water?
(Answer: The cryosphere is all the frozen water on Earth, like ice caps and glaciers. It stores freshwater and helps control the Earth's climate and sea levels.)
400
How does water scarcity harm the environment 4 impacts?
(Answer: Droughts dry up rivers, habitats are destroyed, species die, risk of fires.)
500
What is the difference between groundwater and surface water?
(Answer: Groundwater is found underground in aquifers, while surface water is in rivers, lakes, and reservoirs.)
500
How does building more houses and roads (urban/city environment) impact the water cycle and catchments?
(Answer: More concrete and roads increase runoff and pollution, less water soaks into the ground, natural water cycles are disrupted.)
500
What are two reasons why the Ganges River is important and two major challenges it faces?
(Answer: Important for drinking water and religious ceremonies; challenges include pollution and overuse for farming.)

Name a country experiencing extreme water scarcity and explain why.
Israel Qatar, Israel, Lebanon, Kuwait, and Jordan.
