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

atmosphere
biosphere
hydrosphere
lithosphere

Lithosphere

Explanation:

The earth consists of the atmosphere, the biosphere, the hydrosphere and the lithosphere. The lithosphere refers to the solid part of the earth. Rocks are found both on the earth surface and below the earth surface. Rocks can only be found in the solid part of the earth known as the lithosphere and not in any other earth sphere. Hence the geologist is interested in the lithosphere.

it's filtration, but this is an assumption so my apologies if i got this

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
