Heat from the sun and radiant heat from the core of the earth (caused by the molten core and by radioactive decay) The Green house gases (GHG) like water vapor and CO2 will trap some of the heat making the earth warm enough to support life (~15C instead of ~-18C)
What else can I help you with?
How does heat enter the atmosphere?
Heat enters the Earth's atmosphere primarily through the absorption of sunlight by the Earth's surface, which warms up and then radiates heat back into the atmosphere. Other sources of heat entering the atmosphere include human activities such as burning fossil fuels and deforestation, which release heat-trapping greenhouse gases.
What are the natural sources of methane and how do they contribute to the Earth's atmosphere?
Methane is naturally produced by sources like wetlands, oceans, and animals. These sources release methane into the atmosphere, where it acts as a greenhouse gas, trapping heat and contributing to global warming.
Is it possible to construct a heat engine that creates no air pollution?
No, it is not possible to construct a heat engine that will not expel heat in to atmosphere. according to second law of thermodynamics, all the practical heat engines absorb heat from the source, convert a part of it in to mechanical work and reject the remainder to the cold body or atmosphere. hence, no heat engine can operate with single source for conversion in to mechanical work without expelling heat to the atmosphere. in other words, their must be a temperature difference between the hot and cold bodies (source and sink) for the conversion of heat in to mechanical work.Answer:Hot air is generally not considered a pollutant. Any system that creates mechanical or electrical energy without using fuel would be considered pollution free.A Sterling Cycle engine can use waste (recovered) heat to create mechanical energy. This creates no additional pollution and in fact, as it achieves higher efficiency in the original system, reduces additional fuel use and its associated pollution.Electricity can be generated directly from waste heat by thermocouples of dissimilar metals, again increasing efficiency.Waste heat can be used to boil water to steam for propelling turbines. This recovery creates no additional pollution.Steam from geothermal sources or from solar arrays can alo power engines and turbines without pollution.
What two sources of energy for processes in Earth's lithosphere hydrosphere atmosphere biosphere?
The two main sources of energy for processes in Earth's lithosphere, hydrosphere, atmosphere, and biosphere are sunlight and heat from Earth's interior. Sunlight drives photosynthesis in plants, atmospheric circulation, and water cycle processes. Heat from Earth's interior powers geothermal activity, plate tectonics, and contributes to the internal energy of the planet.
What energy sources drives the atmosphere and hydrosphere?
Energy from the Sun.

How is it possible mercury to have frozen ice?
because Mercury cant trap heat because it has no atmosphere

What are 2 categories of heat sources?
Two categories of heat sources are natural heat sources and artificial heat sources. Natural heat sources include the sun, geothermal energy, and volcanic activity. Artificial heat sources include electric heaters, gas heaters, and oil heaters.
What is the total energy input into the atmosphere from all sources?
The total energy input into the atmosphere comes from various sources such as solar radiation, geothermal heat, and human activities. Solar radiation is the primary source, providing the majority of the energy input. Geothermal heat from Earth's interior also contributes, while human activities such as burning fossil fuels and deforestation add additional energy to the atmosphere.

What are the sources of internal heat?
Main sources of internal heat are Magmatism and Radioactivity.
What heat sources causes burns?
All heat sources. Plus extreme cold sources cause burns.
