On a summer camping on the coast trip, maria and her family hunted for sharks teeth. sharks teeth are fossilized remains of ancient sharks that trolled the waters for prey. to their surprise they found other fossil remains, remains that changed as they dug farther from the shore. a sample of the fossils they found are seen here. what do the fossils tell us about the area? a) all life once lived in the oceans. b) the climate changed over the years. c) it was once underwater; now it is not. d) the habitat stayed the same; the animal species changed.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
