Well it depends what heat you are refering to. One source is the sun, the other source is gas - which can be used as a heating source.
sun is the primary energy source that drives all weather events
Sunlight is the main source of energy on earth
The Sun is the primary source of all energy on Earth.
from convection and the heating
This is true, and also for heating the earth's surface and the oceans. The only other source is the heat from the centre of the earth. Man-made activities are small by comparison.
The sun and uneven heating of the earth's surface causes all the weather.
I think either geothermal or wind

Sunlight is the main energy source for life on earth.
Most life on earth, gets there energy source from the sun, that is assuming that the majority of life on earth are autotrophs (plants). They get this energy by photosynthesising and getting a energy source called glucose, which is used in nearly all organisms on earth... they can then use glucose as a respiratory substrate, for respiration... Hope this helps :)
