A big huge impact with another body - planet, moon, asteroid, etc. Possibly a big enough volcano would eject material into space, but it would not be able to break free of gravity and would instead come raining back down sooner or later. Oh, and you're gonna love this.... The big meteorite, asteroid or comet impact sounds like a candidate. Same with the volcano. No doubt about the planetary collision scenario. But consider that some nuclear tests have thrown material out away from earth far enough for it to be swept away by the solar wind.
that can lead to great hottness or coldness for the planets vem though they are miles and iles away from each other people dont have a answer for sure but they do for 75% out of 100% which is a lot and not alot for it to be sure it has to be more then a 100% or 100%
Earth's rotation causes mantle convention. But you already knew that! :P
the earth's mantle is brown
Thinning of the Earth's crust is caused by the Earth's mantle heating up and expanding. As the mantle expands, large areas of the crust fall in, where they are melted.
Convection currents in the mantle are what causes tectonic plates to move. Uneven heating of the mantle results from radioactive decay of some long-lived isotopes in the mantle, which are not evenly distributed.
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.

there are 7 layers in earths mantle.
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.
Volcanoes are caused by the rising of magma in the earths mantle and earthquakes are caused by the colliding of the earths tectonic plates against one another.

you will find it in earths mantle because it is a kind of an igneous rock
