It underscores the necessity of protecting our natural habitats and the role of various Earth systems like the lithosphere, hydrosphere, atmosphere, and biosphere in maintaining equilibrium.
Practicing Geography Chapter 5 Water Class 7 MCQ with answers assists students in testing their knowledge and enhancing their comprehension of key ideas. These MCQ Questions for Class 7 Geography Chapter 5 make learning engaging and effective, aiding students in exam preparation.
When you first studied the Water chapter in Class 7 Geography, you will think it is just about oceans and rivers. But as you read deeper, you will realize how important it is in our daily life and even for our future.
This chapter showed that although Earth looks full of water, very little of it is actually drinkable. Learning about groundwater, glaciers, and the water cycle made me more aware of how precious fresh water really is.
After this chapter, you will even start reminding your family not to waste water at home.
Chapter 5 Water wasn’t just another Geography lesson it is a reminder that water is life, and we need to protect it.

| Category | % of Total Water on Earth | % of Freshwater | Key Notes |
| Oceans (Salt Water) | ~96.5% | – | Largest share, not usable for direct drinking/irrigation. |
| Glaciers, Ice Caps & Permanent Snow | ~1.74% | ~68% | Mostly in Antarctica, Greenland, and mountain glaciers; inaccessible for daily use. |
| Groundwater (Fresh) | ~0.76% | ~30% | Stored in aquifers underground; major source for drinking and irrigation. |
| Groundwater (Saline) | ~0.93% | – | Found in deep layers, not suitable without desalination. |
| Surface Freshwater (Rivers, Lakes, Wetlands, etc.) | ~0.013% | ~1.2% | Very small fraction but most directly available for human and ecological needs. |
| Rivers | ~0.0001% | ~0.49% of surface water | Crucial for drinking, transport, irrigation, but extremely limited in volume. |
| Lakes | ~0.007% | ~20% of surface water | Store a larger share of surface fresh water compared to rivers. |
| Swamps & Wetlands | ~0.003% | ~30% of surface water | Important for ecosystems, biodiversity, and water storage. |
| Atmosphere (Water Vapour) | ~0.001% | – | Drives the water cycle, rainfall, and climate regulation. |
96.5% = Salt water in oceans.
2.5% = Fresh water (but mostly frozen in ice or underground).
<1% = Easily available fresh water (rivers, lakes, wetlands).
