Which statement correctly compares the thicknesses of earth’s layers?

Option D, Earth’s lithosphere is thinner than its asthenosphere

Explanation:

The complete question is as follows -

Which statement correctly compares the thicknesses of Earth’s layers?

A. Earth’s mantle is thinner than its oceanic crust.

B. Earth’s outer core is thicker than its mantle.

C. Earth’s continental crust is thicker than its lithosphere.

D. Earth’s lithosphere is thinner than its asthenosphere.

Solution -

Oceanic crust and Continental crust are not the layers of earth. There are majorly three layers of earth crust – a) Core, b) Mantle and c) crust.

The core is further divided into inner core and outer core. Therefore, comparison between earth’s layers will be possible when the characteristic of three layers (physical, chemical etc.) are compared with each other. Lithosphere and asthenosphere form the part of crust and hence comparison between them can also be considered as comparison between layers of earth

Thus, option D is correct

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.

explanation:

the denominator has a very specific role.
