Question

Give reason :

1. No one has been able to take samples from the interior of the earth

2. The Continent crust is less dense than the oceanic crust

Answer 1

1. The innermost layer of the earth is called the core. The central core has very high temperature and pressure. So no one has been able to take samples from the interior of the earth.

2. Despite greater thickness, the continental crust is less dense than the oceanic crust because it is made of both light and dense rock types.
