The mantle is the next layer in, after the crust. It is a thick layer of hot solid formed rock, located between the core and the two crusts; oceanic and continental. The mantle starts at approximately 30 km's down and reaches about 2900 km's thick. It is created mainly of perioditite rock - a dense grained igneous rock. This is also a tougher form of rock. than the ones used in the oceanic and continental crusts. With the temperatures in the mantle increasing, any rocks formation changes. For example, the mineral olivine will change when it reaches a destination of around 400 km's, but it will also form again at 700km's.
When travelling through the first 80 km's of the mantle, you would find it to obtain hard and ragged rocks. After that the next 241 km's would be heavily heated rock. However after them periods, you would expect to discover solid and sturdy rock.
It has been researched that the mantle has 3 different layers, upper, lower and controversial.
Upper - A thin flat area lying obtaining the right at the very top of the mantle.
Lower - The lower part of the mantle starts 660 km down, and reaches 2700 km
Controversial - This section is located at the base of the mantle, closest to the core and is estimated at 200 km thick.
