Answer 1

Explanation:

The gaseous envelope around the earth is known as

atmosphere. The lowest layer of this is extended upto 10 km

from sea level, this layer is

(a) stratosphere (b) troposphere

(c) mesosphere (d) hydrosphere

• The troposphere is the lowest layer of the Earth's atmosphere. The air is very well mixed and the temperature decreases with altitude. Air in the troposphere is heated from the ground up. The surface of the Earth absorbs energy and heats up faster than the air does.
