Answers
Answer:
1. Internal forces are done when the rock plates move inside earth or show movement. External forces are done when there is pressure of water, air etc
Internal forces causes a change in the nature and shape of a landform. External forces cause weathering and denunciation.
2. River, wind, sea water and glaciers.
3. Transported soil is blown or washed away from its parent rock. Residue soil remains at the place of formation.
Transported soil is extremely fertile. Residue soil is less fertile.
4. It is formed by the deposition of sediments that is carried by a river.
5. It is because they get enough water through the water vapour present in the atmosphere due to hige amount of humidity which ultimately helps in easy humus creation .
