convections purpose it to "recycle" warm and cold air or materials
Winds are examples of convections currents
They occur in the upper mantle and the convections come from the inner core but travel to the upper mantle.
the purpose is to save energy
the purpose is to help people find their way around the world
Physical features of the earth do not have or need a purpose. They simply exist.
It's "convection" (not convections),but those are the words used to describe the three methods of heat transfer.
False.
Winds are examples of convections currents
The Earth's core.
They move the hot and colder parts around.
Warm air rises, and cool air sinks.
hot, less dense air rises
convections
the convection currents will stop
They occur in the upper mantle and the convections come from the inner core but travel to the upper mantle.
noting it works (in the science meaning; to cause a change) a lot.
The conventional currents will continue until the temperature of the substance is equal to surrounding temp.
