FAQs on Water and Rocks Video Lecture - Science Olympiad for Class 2
| 1. How do water and rocks interact with each other in nature? |  |
Ans. Water and rocks interact in various ways in nature. Water can erode rocks over time, leading to the formation of rivers, canyons, and other geological features. Rocks, in turn, can affect the quality and composition of water as it flows over or through them.
| 2. What role do rocks play in the water cycle? | |
Ans. Rocks play a crucial role in the water cycle by storing and releasing water. Porous rocks, such as sandstone or limestone, can hold water like a sponge and slowly release it back into the environment through springs or groundwater.
| 3. How do rocks contribute to the filtration of water? | |
Ans. Rocks act as natural filters for water by trapping impurities and sediment as water flows through them. This helps to improve the quality of water by removing harmful substances and pollutants.
| 4. What types of rocks are most commonly found near bodies of water? | |
Ans. Sedimentary rocks, such as sandstone, shale, and limestone, are commonly found near bodies of water. These rocks are formed from the accumulation of sediments over time, often in aquatic environments.
| 5. Can water cause rocks to change their physical appearance? | |
Ans. Yes, water can cause rocks to weather and change their physical appearance over time. Processes such as freeze-thaw cycles, chemical weathering, and erosion can alter the shape and structure of rocks when they come into contact with water.
