Why is water essential for growing crops in agriculture?
Water is essential for growing crops because it helps plants absorb nutrients, carry out photosynthesis, and maintain structure and growth.
How do droughts affect communities?
Droughts reduce water supply, harm crops, and affect livelihoods
Explain how transpiration contributes to the water cycle.
Transpiration is the process where plants release water vapour into the air through leaves.
Explain the difference between surface water and groundwater.
Surface water is found in rivers, lakes, and reservoirs; groundwater is stored underground.
How does climate change affect global water distribution?
Climate change alters rainfall patterns, causing droughts and floods, affecting water availability worldwide.
Describe the impact of industrial water use on the environment.
Industrial water use can lead to pollution, habitat destruction, and depletion of water resources.
Discuss the challenges of providing clean water in developing countries.
Lack of infrastructure, pollution, poverty, and political issues make it hard to provide clean water.
