The heat present in the Earth is due to several factors. The first source of heat is from the remnants of heat from impacts with planetesimals early in Earth's history. Impacts with large bodies such as these (including the impact which led to the formation of the moon) trapped the thermal energy of the collision in the surrounding rock of the planet, and may have been enough in certain circumstances to completely melt the early Earth. The second source of heat is also a remnant of an early Earth event known as the Iron Catastrophe. With much of early Earth still molten, denser metals, particularly iron and nickel, migrated to the center of the planet. Tremendous amounts of frictional heat was created, enough to completely melt the planet once again. The third source of heat in the Earth is from compression due to gravity. The fourth and final source of heat in the Earth is from the decay of radioactive elements. This source of heat is gradually declining due the decreasing amounts of radioactive isotopes, the decrease being caused by the decay.

it heats it up because the room temp is hot cause your bodys hot that's why.
How does a water heater work?
"A water heater stores water in a tank and heats the water with a flame at the bottom. The hot water rises to the top of the tank, while the colder water falls to the bottom near the heat source." A water heater is simply a tank of water with a heat source at the bottom. It can be set to a certain temperature and is dispersed throughout the home through the water infrastructure.
What are advantages of radioactive decay?
One reason is that radioactive decay heats the earths interior
WHY IS THAT THE EARTHS INTERIOR IS BELIEVED TO HAVE HIGH TEMPERATURES?
The interior core contains many nuclear properties which gives of huge amounts of heat which then heats the core.

What is the seismic wave that travel's through the earths interior?
A body wave is a seismic wave that travels through Earths interior.
What process occurs when the sun heats water on the earths surface?

Is it hot in the earths mantle?
Decay of radioactive elements in the mantle heats it.
What is the main thing scientist observe in order to learn about the makeup of the earths interior?
Scientists use seismic waves to study Earth's interior. Seismic waves travel through the Earth and can be detected far from their source.
How does temperature of earths crust compare to the temperature of earths interior?
it depends on the deepth
