1. How is the Earth's atmosphere heated? Discuss
in detail.​

Answer 1

Answer:

Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.

Answer 2

Answer:

The Earth’s atmosphere does not get heated directly by the heat of the Sun. Since

the atmosphere is largely made up of gases, most of the solar radiation passes

through it to the Earth. The Earth being solid gets heated. The Earth, in turn, causes

the atmosphere to be heated. The heating of the atmosphere takes place through

convection, conduction, radiation and advection.

The vertical transfer of heat through rising warm air and sinking cold air is called

convection and the currents of moving air formed thus are called convection

currents. Massive convection currents are formed over the Earth, which transfer

heat from the Earth to the upper parts of the atmosphere.

Conduction is the passing of energy from one body to another when they are in

direct contact, through collisions between the molecules of the two bodies.

Conduction is one of the ways that energy is transferred from the Earth’s surface to

the air. Thus, heat is passed from the warmer Earth to the cooler air.

Radiation is energy transmitted from one body to another in the form of rays or

waves. The Earth absorbs heat from the Sun; it then gives off this heat in the form

of infrared rays, which are absorbed by the atmosphere and heat it up.

Advection is the transfer of heat from one region to the other. When warm winds

mix with the cooler winds, heat energy is passed from the warmer winds to the

cooler winds through the process of advection.
