Earth is warmed from the inside primarily through the process of radioactive decay of isotopes such as uranium, thorium, and potassium found in the Earth's crust and mantle. This decay generates heat, contributing to the planet's internal temperature. Additionally, residual heat from the planet's formation and heat generated by the movement of tectonic plates also play significant roles in warming the Earth's interior. Together, these processes maintain the geothermal gradient, which influences volcanic activity and the dynamics of the Earth's interior.

Water from a natural hot spring is warmed by what inside the earth?

It is warmed by geothermal energy which is created by RADIOACTIVE DECAY http://en.wikipedia.org/wiki/Geothermal_(geology)


How is it that radioactive decay has always warmed the earth from the inside and nuclear fusion has always warmed the earth from the outside?

That's because of where each of these processes occur. There is no nuclear fusion inside of Earth. There is probably a small amount of radioactive decay in the Sun, but the power produced by it is insignificant, compared to the huge amount of power produced by nuclear fusion.


Explain how radioactive decay has always warmed the earth from the inside and how nulear fusion has always warmed the earth from the outside?

The Earth's core contains many radioactive elements within its core that emit warmth as they decay, keeping the core of the Earth hot and heating it from within. Meanwhile, the sun is a product of the nuclear fusion of hydrogen into helium and its rays warm the Earth's crust from outside.

In which layer of Earth's atmosphere is air most likely warmed by conduction?

The troposphere is the layer of Earth's atmosphere where air is most likely warmed by conduction. This is the lowest layer of the atmosphere where weather events occur, and conduction is the main mechanism through which heat is transferred near the Earth's surface.


What atmosphere in the air is warmed by heat from Earth's surface?

The lower atmosphere, known as the troposphere, is warmed by heat from Earth's surface. This warming is due to the absorption of outgoing radiation by greenhouse gases such as carbon dioxide and water vapor, which trap heat in the atmosphere.


The surface of the earth is warmed mainly by conduction or convection or radiation?

The surface of the Earth is primarily warmed by radiation from the sun. The sun emits heat in the form of electromagnetic radiation that is absorbed by the Earth's surface, warming it up. Conduction and convection also play a role in distributing this heat throughout the atmosphere and the oceans.
