Where could convection currents form? check all that apply.

in a sand dune

in a freshwater lake

in the atmosphere

in outer space

in earth’s mantle

in a freshwater lake

in the atmosphere

Explanation:

Here we know that convection currents are defined as the flow of medium molecules due to the density difference as we know that less density molecules always lie on the top of the fluid due to upthrust of heavy molecules.

So here when temperature is changing in different layers of fluids then due to temperature gradient there is flow of fluid molecules along with thermal energy

This flow of thermal energy along with the molecules is known as convection current.

So here correct answer would be

in a freshwater lake

in the atmosphere

dang that balls went far
