Ageologist studies rocks. which of earth's spheres would a geologist be most interested in? atmosphere biosphere hydrosphere lithosphere

When a geologists studies the rock, he must be interested in lithosphere, the sphere of Earth which has the rock.  

Option D

Explanation:

Lithosphere is the sphere with the rock and soil component, broadly speaking the land. Lithosphere is the sphere where the rocks are present above the mantle (upper mantle) and the crust.

They had the rock which are solid in state and are consider to be of elastic nature with low ductility. There are broadly two main categories based upon the location of their presence, which are oceanic and continental.

frequency or wavelenth of em radiation in a vacuum

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
