What will happen if the Earth stops spinning?
At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
How hot is the mantle?
The upper mantle has a temperature range between 500 degrees and 900 degrees Celsius near the crust. Deep in the Earth at the boundary with the Earth’s core the rock temperature is about 4000 degrees Celsius.

A special planet: the habitable Earth
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Can we live in Pluto?
It is irrelevant that Pluto’s surface temperature is extremely low, because any internal ocean would be warm enough for life. This could not be life depending on sunlight for its energy, like most life on Earth, and it would have to survive on the probably very meagre chemical energy available within Pluto.
Who discovered planets?
