Q2 of 21 Page 24

If the classification of landforms on land can be done on the basis of altitude and size, then how can the landforms submerged under water be classified?

If the classification of landforms on the land can be done on the basis of altitude and size, then the landforms submerged under the water might be classified based upon their depth or the shape they make with the flowing water that carries the mud, silt and other residues on the way of its disposal in the seas and oceans. These landforms formed by water are usually called the coastal landforms and they include stacks, stumps, caves, arches, bays, coves, beaches and cliffs.

• Continents and oceans are a part of the lithosphere and hydrosphere respectively.

• Continents and oceans lie on plates


• During low tides, the level of ocean water goes down and the land below the water near the coast is exposed.


• Ships wreck when they strike against the rocks in the ocean.


If the above points are correct, then select the most appropriate option from the following:


The surface of the earth is occupied by land and water


There is land below the ocean too.


Even if the water has the same level, the land submerged is not even.


The level of water and land is uneven.


Discuss in the class regarding the choice of your options. Know from your teachers about the correct option.
