What are the two main sources of heat in the troposhere?

The two main sources of heat in the troposphere are solar radiation, which warms the Earth's surface, and the release of latent heat energy from water vapor condensing into clouds and precipitation.


What are the sources of heat within Earth?

The main sources of heat within Earth are residual heat from its formation, radioactive decay of elements like uranium, thorium, and potassium, and heat generated by ongoing mantle convection. This internal heat contributes to processes like plate tectonics, volcanism, and the formation of geothermal energy.


What are two main sources of heating in the earth?

The two main sources of heating in the Earth are radioactive decay of elements like uranium, thorium, and potassium in the mantle, and residual heat from the Earth's formation over 4.5 billion years ago. These heat sources contribute to the movement of tectonic plates and drive processes like mantle convection and volcanic activity.


What are the two main sources of energy in earth's system?

The two main sources of energy in Earth's system are solar energy, which comes from the Sun, and geothermal energy, which comes from the Earth's internal heat.


Two types of heat in are earth?

The two main sources of heat within Earth are primordial heat left over from the planet's formation over 4.5 billion years ago, and radiogenic heat produced by the decay of radioactive isotopes in the mantle and crust. These heat sources drive geological processes such as mantle convection and plate tectonics.
