WebOct 1, 2024 · Scientists believe that convection circulation within the mantle helps continents to move. As heat from Earth's innermost layer—the core—transfers to the bottom layer of mantle rock, the rock warms, softens, and rises upward. This pushes cooler rock … WebConvection. Convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid. Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere ... WebNov 22, 2024 · There are five different layers: Troposphere: The troposphere is the layer of the atmosphere closest to the Earth's surface. This is where all weather and air currents occur and ends ~11 km from the Earth. Stratosphere: After the troposphere is the stratosphere. This level is where jets fly. crystal for protection from evil
