Convection Currents - What are Convection Currents?

A thunderstorm can be the best example of convection currents. The warm water in the air rises upwards and turns into saturated water drops which form the clouds. In this process, the smaller clouds run into each other and hence the bigger clouds are formed. The thunderstorms or cumulonimbus clouds are formed on reaching the final growth stage.

Convection and the Mantle

Convection currents continue as long as heat is added to the fluid. Convection currents flow in the asthenosphere. The heat source for these currents is heat from Earth’s core and from the mantle itself. Hot columns of mantle material rise slowly. At the top of the asthenosphere, the hot material spreads out and pushes the cooler material ...

How does mantle convection affect the plates?

Convection currents happen in fluids with a heat source. The core heats up the magma and causes a convection current. When magma comes to the top of the mantle, it pushes against tectonic plates, which are huge slabs of rock which the crust rests on. Also to know, which processes are caused by convection currents in the mantle? Convection ...

What causes convection currents in the atmosphere?

Feb 26, 2020 A convection current is a process which involves the movement of energy from one place to another. It is also called to as convection heat transfer. The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Secondly, what causes convection? Convection, process by

Jan 19, 2017 Convection currents is formed via heating and cooling of the fluid which changes in the fluid density with the hand of the force of gravity. The currents take place in the core and the mantle. Heat in the mantle is brought about from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending ...

Jun 22, 2021 Where is the convection current source of heat come from? Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

How is density related to convection and convection currents in the mantle?

How is density related to convection and convection currents in the mantle?

Jun 30, 2019 What is density and what does it have to do with a convection current? Convection is heat transfer due to a density differential within a fluid. As water’s temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.

Mar 24, 2020 The convection currents also help transfer heat from Earth’s core, where magma is created through radioactive decay, to the mantle. This heat transfer continues through the layers of the crust until it reaches the surface. The convection currents, as they carry heat upward with the magma, break apart the plates at areas referred to as ...

How do convection currents cause tectonic plates to move?

Sep 02, 2019 The plates move because of convection currents in the Earth’s mantle. These are driven by the heat produced by the natural decay of radioactive elements in the Earth. Where tectonic plates meet, the Earth’s crust becomes unstable as the plates push against each other, or ride under or over each other.
