Water Conservation and Usage Concepts

The video discusses the importance of rainwater harvesting as a method to conserve water resources. It highlights the scarcity of usable water despite Earth's vast water coverage. The growing demands from population, industries, and agriculture are depleting available water. Rainwater harvesting is presented as a crucial conservation strategy, capturing rain before it flows into oceans, thus preserving usable water.

What fraction of the Earth's surface is covered with water?

• 1/3

• 2/3

• 3/4

• 1/2

Why is the amount of usable water on Earth very small?

• Because it is mostly polluted

• Because it is mostly frozen

• Because it is mostly in the oceans

• Because it is mostly underground

What are the main factors increasing the demand for water?

• Population growth, industries, and agriculture

• Mining and construction

• Climate change and pollution

• Deforestation and urbanization

What is one of the major consequences of high water consumption?

• Increased rainfall

• Expansion of water bodies

• Reduction of available water

• Improved water quality

What is a key preventive measure for water conservation?

• Drilling more wells

• Desalination

• Rainwater harvesting

• Building more dams

What happens to rainwater that is not harvested?

• It evaporates

• It gets absorbed by plants

• It flows into the ocean

• It remains in the atmosphere
