ExplanationExplanation1.Earth is formed with the rocks. 2.After a certain depth of surface, earth is not solid

like surface and different character in nature due to high pressure and temperature.

3.Water is not the component of earth4.The basin like portions are filled with water i.e.

ocean basin in the earth crust.5.Rising parts of crust are continents. 6.All the continents and ocean basins are on the

crust.

ELABORATIONELABORATION

• These facts are occurred due to release of heat from earth and contraction takes place and as well as taking its natural shape and present form.

• Earth is formed with the rocks. After a certain depth of surface, earth is not solid like surface due to high temperature and pressure of it.

• Earth crust is comparatively solid in form rather than sub surface materials of the earth.

………………..Cond...Cond. ELABORATION ELABORATION• After various observation by Scientists, all layers

have an average depth and having different specific gravity.

• Earth changes shapes from gaseous form to present shape due to cooling. All the materials concentrated as their specific gravity and try to solidify.

• All the layers are identified by the earthquake wave.

• Different layers react different responses.
