Approximately 3 billion (3,000,000,000) years
The atmosphere balances the unequal heating of Earth's surface by moving air through convection currents. These currents transfer heat from warmer regions to cooler regions, helping to regulate temperature gradients and create more stable climate conditions.
Convection Currents affect earth by slowly moving the tectonic plates
convection
The radioactive decay produces heat energy, which keeps the convection currents moving.
Unequal heating of Earth's surface: Differential heating of the Earth's surface by the sun creates temperature and pressure differences that drive convection currents. Rotation of Earth (Coriolis effect): The rotation of the Earth causes moving air or water to be deflected, which influences the direction of convection currents. Gravitational force: Gravity plays a role in pulling denser, cooler air or water downwards, while lighter, warmer air or water rises, initiating convection currents.
the convection currents in the mantle under the earths curst is moving the broken plates in earths lithosphere causing the plates slide across the lithosphere. this process is called tectonics. (jon lay wrote this,)
If the heat source is removed, convection currents will eventually stop because there is no longer a temperature difference to drive the circulation of the fluid. As the fluid cools down to the surrounding temperature, the convection currents will gradually slow down and dissipate.
surface currents?
THE FORCES MOVING EARTH'S SURFACE ARE UNDERNEATH EARTH'S SURFACE, IN THE UPPER MANTLE. FWI, these forces are actually huge convection currents in the magma buried under Earth's crust.
no
Their evidence comes from rocks at earths surface.
Convection currents are the moving currents of fluid that transfer heat. Heat is transferred through the fluid as warmer, less dense fluid rises and cooler, denser fluid sinks, creating a continuous circulation pattern that transfers heat throughout the fluid.
