the air being heated from a fireplace,air from a furnace,boiling water,the air being heated in a hot air balloon.
False.
The Earth's core.
They move the hot and colder parts around.
hot, less dense air rises
Warm air rises, and cool air sinks.
convections
the convection currents will stop
noting it works (in the science meaning; to cause a change) a lot.
The purpose of convection is to transfer heat from one place to another through the movement of fluids (liquids or gases). This process helps distribute heat more evenly in a space, such as in a room with a radiator or in the Earth's atmosphere through weather systems.
The conventional currents will continue until the temperature of the substance is equal to surrounding temp.
a the convections currents of earth would slow down and eventually stop. by the way, I'm 12
when the hot air rises up with low density , it gets absorbed by the surrounding cool air,which then sinks down due to the high density that is how the energy is transfered
