How do convection currents affect tectonic plates? Socratic

Apr 09, 2016 Explanation: Convection currents happen in fluids with a heat source. Hot liquid or gas near the heat source becomes hotter and less dense, so moves upwards. This forces the cooler stuff at the top to move back down. As the hot molecules move up, they cool down and begin to drop. As the cool molecules move down, they heat up and begin to rise.

Apr 11, 2022 1) Radiogenic heat production increases the mean mantle temperature and strengthens the vigor of mantle convection. This increased mantle temperature reduces the thickness of the thermal lithosphere. What is a radiogenic element? A radiogenic nuclide is a nuclide that is produced by a process of radioactive decay. …

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 ...

In Earth: The outer shell. Slow convection currents deep within the mantle generated by radioactive heating of the interior drive lateral movements of the plates (and the continents on top of them) at a rate of several centimetres per year. The plates interact along their margins, and these boundaries are classified….

Jan 29, 2020 How does the mantle move the crust? Heat from the core causes convection currents in the mantle. These currents slowly move the crust around. Their movement is driven by convection currents in the mantle. The mantle is much hotter than the crust and its rock is molten . Click to see full answer. Herein, how does the earth's crust move?

Mar 24, 2020 Twitter. Convection currents in Earth’s mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle. The convection currents also help transfer ...

Convection and the Mantle

This flow that transfers heat within a fluid is called a convection current. The heating and cooling of the fluid, changes in the fluid’s density, and the force of gravity combine to set convection currents in motion. Convection currents continue as long as heat is added to the fluid. Convection currents flow in the asthenosphere.
