b.The total energy available in the Universe minus Earth's energy use.
c.The total energy output by the Sun minus all the solar system planets' energy use.
d.The total energy output by the Sun plus the energy reflected by Earth's atmosphere back into space.

Answer 1

A) The balance between the amount of energy coming into Earth from the Sun and going back out into space.

Answer 2

Answer:

A.The balance between the amount of energy coming into Earth from the Sun and going back out into space.

Explanation:

Sun is the ultimate source of energy for earth. Earth's surface and atmosphere absorb the heat from incoming solar radiations during day time. A part of the absorbed heat is then reflected back into the space during night. This balance between absorbed and reflected energy from earth is called as Earth's energy budget and it maintains the global temperature of earth.
