essential questions

1.How do we know earth crust or lithosphere is broken into plates?
2.How do we come to know that these plates are moving?
3.How do we know that mantle and beneath is a made of hot liquid lava?
4. How do the various weathering agents keep changing the crust of the earth?


  1. How do we know the plates move?
  2. What forces are involved in the evolution of  the landforms? Give example for  each force.
  3. What are lithospheric plates?
  4. Define weathering.
  5. Define erosion.


  1. How can we minimize the impact of the earthquake?
  2. What causes earthquake and volcanoes?
  3. What is a volcano? Draw a labeled diagram
  4. Write the difference between weathering and erosion.
  5. Write a detail of various landforms that are created by river from its source of origin until it reaches the sea.
  6. How is coastal landforms different from river based landforms.
  7. Write a detailed account of all the landforms created by sea water.
  8. Write the difference between exogenic and endogenic forces.


  1. Write the correct word for the following: a) Its another water body that is formed by the river when it meanders in the flood plains    b)  I am able to break big rocks and boulders   c) I wear away of the landscape by different agents like wind, water and ice  d) I am formed at the end of river’s journey near the sea  d) Waves keep hitting the rocks so hard that only the roof of the cave rock remains  e) I get my name from a fungi because winds erode the lower section of the rock giving me the shape of that fungi
  2. How does the earthquake travel from the focus? Explain in detail?
  3. Why does the river slow down at the mouth of the river? How is delta formed?
  4. How are mushroom rocks formed?
  5. How are waterfalls created?


  1.  Compare how the river’s journey is different when it flows in the hills and when it flows in the plains.
