What Are Convection Currents? - Science Trends

Dec 23, 2019 Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global-scale flow of magma. The Earth is made out of a number of different layers ...

Feb 21, 2020 How do convection currents move the crust? 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. Click to see full answer.

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

Jun 30, 2019 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. ... This creates a current within the fluid called Convection current. The mantle within the earth’s surface flows due to convection currents.

Mantle Convection - an overview ScienceDirect Topics

Mantle convection and plate tectonics provide a general framework for understanding tectonophysics. Transport of heat from the interior of the earth drives solid-state convection. Plate tectonics is a direct consequence of this convection. The relative velocity between plates causes crustal deformation at the boundaries between plates.

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 ...

Scientists believe that convection circulation within the mantle helps continents to move. As heat from Earth's innermost layer—the core—transfers to the bottom layer of mantle rock, the rock warms, softens, and rises upward. This pushes cooler rock downward. The cycle repeats, creating convection currents.
