Olympiad Test: Water - 2 - Class 6 MCQ

Floods lead to crop damage, soil erosion, waterlogging, and increased risk of waterborne diseases, but they do not directly cause increased rainfall.

Drought is a prolonged period of abnormally low rainfall, leading to reduced soil moisture, lower water levels in rivers and lakes, and scarcity of water for humans, animals, and crops.

During droughts, water availability for drinking, agriculture, and industry is significantly reduced, leading to scarcity and water rationing.

Insufficient water during drought periods reduces soil moisture, inhibits crop growth, and can lead to crop failure, food shortages, and economic losses for farmers.

By collecting and storing rainwater, communities reduce dependency on rivers, lakes, and groundwater for non-drinking purposes, preserving these sources for essential uses.

Rainwater harvesting involves capturing rain from rooftops, land surfaces, or catchment areas and directing it to storage tanks or reservoirs for future use.

Harvesting rainwater conserves water by supplementing existing freshwater resources and reducing pressure on rivers, lakes, and groundwater.

Condensation occurs when water vapor cools in the atmosphere and forms tiny droplets, which cluster together to form clouds.

Surface water refers to freshwater that exists above the ground in rivers, lakes, ponds, and streams, which is accessible for human use.

Efficient irrigation, water recycling, and water conservation reduce the impact of drought by ensuring optimal use of limited water resources.
