WebIn this way, it flows like a convection current, radiating heat outward from the Earth's interior. Above the asthenosphere, at the same rate of deformation, rock behaves elastically and, being brittle, can break, causing faults. WebAnswer: The theory of plate tectonics suggests that the lithospheric plates move because of convection currents in the semi molten mantle. Explanation: Convection currents can be observed on the surface of a hot liquid. If there are minerals in the liquid that can solidify as they cool, the minerals are observed to form plate like structures.

Convection Currents - 8TH-GRADE SCIENCE

WebConvection 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. Web28 sep. 2024 · Heat within the asthenosphere creates convection currents (similar to the currents that can be seen in the lava lamp). These convection currents cause the … birthday alarm christmas cards

What do convection currents do in the Lithosphere? - Answers

WebB. Convection current causes the lithospheric plate to move in any direction. 30. A convection current is caused by differences in temperature resulting to variation in. … WebEarthquakes and volcanoes are concentrated at the boundaries between lithospheric plates. It is thought that plate movement is caused by convection currents in the mantle (Fig. 2), although the exact mechanism is not known. Lithosphere plates are moving at rates of a few cm per year. WebSubduction zones, where downward convection currents occur (Figs. 1, 2c), involving two lithospheric plates (an upper horizontal one and a lower inclined one). birthdayalarm.com phone number
