How do convection currents cause plate movement?

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.Click to see full answer. Also know, why do convection currents cause plates to move?Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.Similarly, what are the 3 causes of plate movement? Mantle convection currents, ridge push and slab pull are three of the forces that have been proposed as the main drivers of plate movement (based on What drives the plates? Pete Loader). There are a number of competing theories that attempt to explain what drives the movement of tectonic plates. Accordingly, how do convection currents cause earthquakes? The Earth’s crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. Plate tectonics cause earthquakes and volcanoes .How do convection currents move in the mantle?Convection currents in the air and sea lead to weather. Magma in the Earth’s mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The magma can’t continue to rise, so it moves horizontally and sinks back down.
