This reduction in overlying … WebMar 24, 2024 · Mantle convection is the process by which heat from the Earth’s core is transferred upwards to the surface. It is thought that heating of the mantle by the core … WebWhy does mantle convection occur? Mantle convection occurs because relatively hot rocks are less dense and rise in a gravitational field while relatively cold rocks are more dense and sink. The rise of hot rocks advects heat upward while the fall of cold rocks advects cold downward; this counterflow is equivalent to an upward heat flux. dare bee back exercises

The rock is in a semi-liquid state and should behave like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from the heat of the earth’s core.

WebSep 12, 2024 · Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material. Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy.
