Answer 1

Explanation:

There are very small differences between the two layers. The upper mantle has Olivine (a very special rock), compounds with silicon dioxide, and a substance called Peridotite. The lower mantle is more solid than the upper mantle.

Answer 2

The first difference between the upper mantle and lower mantle is their location. The upper mantle adjoins the crust to form the lithosphere, whereas the lower mantle never comes in contact with the crust.Temperature is one of the differences between the two upper layers of the mantle. The upper mantle’s temperatures range from 932 to 1,652 degrees Fahrenheit (or 500 to 900 degrees Celsius). The lower mantle temperature, in contrast, reaches over 7,230 degrees Fahrenheit or 4,000 degrees Celsius.Pressure is one great difference between the upper and lower mantle. The viscosity of the upper mantle is greater than the viscosity of the lower mantle.
