Convection currents in water (or any fluid) are the movement of the water caused by a difference in temperature between the upper and lower layers of the water. As water is heated it becomes lighter than cooler water so it floats up. Conversely, as water is cooled it get heavier so it sinks.
Assume the weather has been warm and the water in a pond is warm, then a cold spell comes through. The cold air cools the water at the surface causing it to sink. As it goes down into the warmer water it's heated and as more cooled heavier water sinks it pushes the newly warmed water up. This continuing process will eventually cause this original cooled and rewarmed water to reach the surface where it will be cooled and sink again and the process repeats until the entire pond is at the same temperature. This sinking and rising is called convection and the moving water is called convection currents.

What is the importance of convection currents to pond life?
The convection currents move around oxygen and other good nutrients throughout the pond, where is is no other flow.

What is the relationship between convection currents in the ocean and convection currents in the atmosphere?
Which best explains the relationship between ocean currents and convection currents?(1 point) Responses Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents create a Coriolis effect that increases convection currents. Ocean currents create a Coriolis effect that increases convection currents. Convection currents use the Coriolis effect to generate ocean currents.
How thick are the convection currents?
The convection currents are in the mantle😱
Convection currents discovered date?
convection currents discovery date
The layer in which convection currents move?
Convection currents move in the Mantle.
What direction do convection currents-move?
Convection currents move in upward direction
Do scientists think plates are moved by convection currents or volcanoes?
convection currents.
Do convection currents cause earths heat?
No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
Do convection currents connect the poles all the way to the equator?
Yes, convection currents connect the poles all the way to the equator.
