Question

Where could convection currents form? Check all that apply.

Answer 1

Answer:

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

Answer 2

I believe the correct answers from the choices listed above are options 2nd and 3rd. Convection currents form in liquids and gases so it should be in a freshwater lake and in the atmosphere.

Hope this answers the question. Have a nice day.
