Identifying energy from the sun
identify characteristics of energy from the sun. check all that apply.
almost all of the energy on earth comes from the sun.
energy from the sun is known as mechanical energy
the energy in fossil fuels originally came from the sun
plants convert the energy of sunlight into chemical energy.
