Chapter 15: Problem 2208

If the earth were not having atmosphere, its temperature (A) would have been low (B) would have been high (C) would have remain constant (D) none of these

Short Answer

Expert verified
If the Earth had no atmosphere, it would not be able to retain heat through the greenhouse effect, leading to a significant drop in temperature. Therefore, the correct answer is (A) would have been low.

Step by step solution

01

Understand the role of the atmosphere

The atmosphere plays a crucial role in the Earth's temperature regulation. It helps keep the Earth warm by trapping heat in a process called the greenhouse effect. Without the atmosphere, the planet would not be able to hold onto much of the heat it receives from the sun, and most of it would be lost to space.
02

Consider the Earth without atmosphere

If the Earth were not having an atmosphere, there would be no process to trap the sun's heat near the surface. As a result, most of the heat that the Earth receives from the sun would be lost to the space, leading to a significant drop in the overall temperature of the planet.
03

Select the correct option

Based on the role that the atmosphere has in retaining the sun's heat and considering the scenario without an atmosphere, the Earth's temperature would have been low. Thus, the correct option among the given choices is: (A) would have been low
