Heat from which of these causes convection currents inside earth
Asked by admin @ in Geography viewed by 296 People
What causes convection currents inside the earth crust? Thank You for Answers hope they help.
Answered by admin @
.Answer:
Convection 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
Explanation:
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. The convection currents move the plates.
