Question

What would happen if the earth's orbit suddenly became smaller?

A) The earth's water would evaporate.
B ) The earth's water would freeze.
C ) The earth's atmosphere would float away.
D) The earth's atmosphere would collapse.

Answer 1

The earth's atmosphere would float away.

Answer 2

It's A) The Earth's water would evaporate. This is because due to the smaller orbit, Earth would get closer to the sun; that would, in turn, raise the tempurature on the surface. This would cause the water on earth to evaporate much faster than it naturally does in the water cycle.
