The Sun's energy
A.
Is completely absorbed by the atmosphere
B.
Is completely reflected by the atmosphere
C.
Is in the form of latent heat
D.
Is transferred to the atmosphere after warming Earth

Answers

B.

Is completely reflected by the atmosphere

Explanation:Intense heat and pressure in the Sun's core cause protons to fuse together to form helium atoms, a process that releases large amounts of energy. This nuclear reaction—the same process that takes place in a hydrogen bomb—has powered the Sun for more than 4 billion years.

B

Explanation:

In total, the atmosphere and the Earth's surface absorb approximately 70% of incoming radiation, while the remaining 30% is reflected back to space and does not heat the surface. Because it is colder, the Earth radiates energy at much longer wavelengths than the Sun.
