Shaping of Earth surface
Class 9 Social Science – Chapter 2: Shaping of the Earth's Surface 30 Competency-Based & Long Revision Questions (with Bullet-Point Answers) 1. Explain how endogenic and exogenic forces work together to shape the Earth's surface. • Endogenic forces create landforms through uplift and volcanic activity. • Exogenic forces wear them down through weathering and erosion. • Both continuously modify the Earth's surface. • Together they maintain the cycle of landform development. 2. Why is the Earth's surface constantly changing? Explain with examples. • Internal forces cause earthquakes and volcanoes. • External forces include rivers, glaciers, wind and sea waves. • Weathering and erosion reshape landforms. • Human activities also accelerate changes. 3. Differentiate between weathering and erosion. • Weathering breaks rocks at the same place. • Erosion removes and transports weathered materials. • Weathering does not involve movement. • Erosion involves transpo...
