Which of the following correctly describes where early earth's water came from?

a. rains from violent storms created oceans

b. ice on mountainous structures melted

c. collisions between earth and stars released water

d. carbon in earth's crust converted into water vapor that was then condensed

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

a covalent bond, specfically triple bond
