1. 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. A strong exam answer should also explain how this point connects with Earth is called the Blue Planet because nearly three-fourths of its surface is covered with water, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

2. How can students understand Earth is called the Blue Planet because nearly three-fourths of its surface is covered with water easily?

Students can first listen to the related audio explanation, then revise the key points and solve practice questions based on this topic. A strong exam answer should also explain how this point connects with Earth is called the Blue Planet because nearly three-fourths of its surface is covered with water, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

3. How can Earth is called the Blue Planet because nearly three-fourths of its surface is covered with water be used in exams?

A strong exam answer should also explain how this point connects with Earth is called the Blue Planet because nearly three-fourths of its surface is covered with water, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

4. 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.

7. 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.
