What process occurs when mechanical energy is transferred to chemical energy

Chemical energy is turned into mechanical energy in the internal combustion engine. The heat of the chemical reaction (fuel and air) expands the gas and this pushes down on a piston. ... Heat is a different form of energy.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
