Question

The average temperature of the Earth remains fairly steady as compared to that of the moon because of the ….
A. Atmosphere
B. Lithosphere
C. Biosphere
D. Hydrosphere

Answer 1

Hint: Earth has the right temperature for living beings.The moon is a satellite of earth and moves round it.

Complete answer:
The average temperature of earth remains steady as compared to moon, the weather of earth is also suitable for life, now let’s see reason behind this from given option,

The air is a poor conductor of heat. During the day, it prevents a sudden increase in the temperature of the earth and prevents the heat from escaping to outer space during the night. It keeps the average temperature of the earth steady.Moon has no atmosphere and the temperature ranges from 121°C during the day to -157°C at night.
The lithosphere is the solid and outer part of the Earth. The lithosphere contains the brittle upper portion of the mantle and the crust of the outermost layers of Earth's structure. It's bounded by the atmosphere above and the asthenosphere which is the other part of the upper mantle, below.
Biosphere is relatively thin, life-supporting stratum of Earth's surface. It extends from a few kilometers into the atmosphere.
The hydrosphere contains water which is on the surface of the planet, present underground, and in the air. A planet's hydrosphere can be in the form of liquid, vapor, or ice.

Therefore the correct answer is A. Atmosphere.

Note: The average temperature of the Earth remains fairly steady as compared to that of the Moon because of the atmosphere. It is the layer of gases surrounding the planet. Atmosphere, along with other factors, is altogether responsible for life on earth.
