Question

sun heats earth due to conduction. true or false?​

Answer 1

Answer:

False

Explanation:

Heat from Sun reaches us by the process of radiation. As we know radiation do not need any material medium for heat transfer. It takes place in the form of electromagnetic radiations. In space (where there is Sun) there is no atmosphere, no medium, so convection can't take place. By radiation only heat can be transmitted by Sun to earth.

I hope this might be helpful☺.

Answer 2

Answer:

False

Explanation:

Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction.
