Question

• A. lower
• B. higher
• C. same as now
• D. $0^{0}C$

Answer 1

The correct option is A lower

If there was no atmosphere around the earth, the temperature will decrease. Earth's atmosphere traps heat from the sun and keeps it near to the surface of the earth, popularly known as green house effect. It keeps warming the planet and sustaining life on earth. If there were no atmosphere, the average temperature drops below zero.

Thus the correct answer is option A.
