Give an account of the work of wind?
Wind is an active agent of erosion and deposition in the deserts. In deserts, we often notice rocks in the shape of a mushroom, known as mushroom rocks. Winds erode the lower section of the rock more than the upper part. Therefore, such rocks have a narrower base and a wider top. When the wind …
Explain the work of a river.
The running water in the river erodes the landscape. When the river tumbles at a steep angle over very hard rocks or down a deep valley side it forms a waterfall. While entering the plain the river twists and turns and forms large bends which are known as meanders. Due to continuous erosion and deposition …
Give an account of earthquake preparedness.
Earthquake is a natural calamity which we cannot stop. But we can minimise its impact if we are prepared before-hand.During an earthquake, we should shift to some safe spot. We should hide under a kitchen counter, table, or desk against an inside comer or wall. We should stay away from fireplaces, areas around chimneys, windows …
What is an earthquake? What are some common earthquake prediction methods?
When the lithospheric plates move, the surface of the earth vibrates. The vibrations can travel all around the earth. These vibrations are called earthquakes. Some common earthquake prediction methods include studying animal behaviour, fish in the ponds get agitated, snakes come to the surface.
Mention the work of ice?
Glaciers are rivers of ice that erode the landscape by destroying soil and stones to expose the solid rock below. Glaciers carve out deep hollows. As the ice melts they get filled up with water and become beautiful lakes in the mountains. The material carried by the glacier such as rocks big and small, sand …
Name a few rivers of the world that form a delta?
Nile, Zaire, Ganga-Brahmaputra, Hwangotto, Murray-Darling, Amazon, etc.
What does the process of erosion and deposition create?
The process of erosion and deposition create different landforms on the surface of the earth.
Name the two processes which wear away the landscape.
Weathering and erosion.
How are glacial moraines formed?
The material carried by the glacier such as rocks big and small, sand and silt gets deposited. These deposits form glacial moraines.
