FAQ
What is the difference between salty water and freshwater on Earth?
About 97% of Earth's water is salty and found in oceans, which is not suitable for drinking or farming. Only 3% is freshwater, mostly locked in glaciers or underground, which we use for daily needs. You can listen to the full explanation on Harshali Academy.
Why do cities with good rainfall still face water scarcity?
Cities like Chennai and Bengaluru face water scarcity because rainwater quickly runs off without soaking into the ground, and heavy reliance on groundwater leads to depletion. Harshali Academy’s audio lessons explain this in detail.
How does population growth affect water resources?
Population growth increases demand for drinking water and food, leading to more irrigation and over-exploitation of water resources. Harshali Academy provides examples and solutions in its chapter audio.
How can teachers use this chapter to help students prepare for exams?
Teachers can focus on key concepts like the hydrological cycle, causes of water scarcity, and groundwater depletion. Using Harshali Academy’s audio lessons alongside notes helps reinforce understanding and exam readiness.
What practical steps can students learn from this chapter to conserve water?
Students learn about the importance of managing water use, avoiding wastage, and understanding the limits of freshwater availability. Harshali Academy encourages awareness through engaging content.
Important exam questions with answers
Why is Earth called the Blue Planet?
Earth is called the Blue Planet because nearly three-fourths of its surface is covered with water, mainly oceans and seas. This blue appearance is visible from space due to the vast water bodies.
Explain the hydrological cycle and why water is considered a renewable resource.
The hydrological cycle is the continuous movement of water from Earth’s surface to the atmosphere and back through evaporation, condensation, precipitation, and runoff. Because this cycle keeps renewing water, water is called a renewable resource.
What are the main causes of falling groundwater levels in India?
Falling groundwater levels are caused by overuse for irrigation, rapid urbanisation, and increasing population demand. Excessive pumping of groundwater without adequate recharge leads to wells drying up.
Key concepts from this chapter
- Earth is called the Blue Planet because nearly three-fourths of its surface is covered with water.
- About 97% of Earth's water is salty and unusable for drinking or farming; only 3% is freshwater.
- The hydrological cycle describes the continuous movement of water from Earth to atmosphere and back, making water a renewable resource.
- Water scarcity occurs due to over-exploitation, unequal distribution, and poor management despite water being renewable.
- Groundwater levels fall due to excessive use for irrigation, urbanisation, and population growth, leading to water shortages even in rainy areas like Chennai and Bengaluru.
