Can you attach a picture maybe?
Convection is a process which transfers the heat between the temperatures when fluid (i.e. liquid or gas) is in motion. Due to the presence of heat source, water temperature increases and also it will become less dense and rise. Hot air is less dense than cold. When air rises higher in the atmosphere its pressure gets down and it becomes colder.
About 500BCE, the Aryans began to
compose a body of texts called Vedas based on
their traditional stories. Veda is a Sanskrit
word that means knowledge. The Rig Veda is a
collection of more than 1000 poems that
survives to this day. The influence of these
stories of the Aryan people on the subcontinent
is why historians label the period of Indian
history lasting from about 1500BCE to 322BCE
as the Verdict Age. SORRY IT'S SO LONG
