how is heat transferred on earth?

air cells
radiation
convection
nitrogen cycle
insulation
conduction

Option

B) Radiation

C) Convection

D) Conduction

Explanation:

The heat is transferred through three methods on planet earth-  

a)Conduction – The heat in conduction is transferred from molecule to molecule and thus contact between two things is necessary for heat transfer. For example – the surface of earth absorbs heat and eventually transfers it to the air near to it. Thus the air which is close to earth’s surface is warmer than air above it.  

b)Convention – In this the heat moves from place to place such as movement of warm air

c)Radiation – Greenhouse gas affect is caused by back radiation of heat from earth’s surface .

Yes, there are nuclear reactions constantly occurring in our bodies, but there are very few of them compared to the chemical reactions, and they do not affect our bodies much. ... blah blah
