Question

distinguish between upper crust and lower crust​

Answer 1

The upper mantle adjoins the crust to form the lithosphere, whereas the lower mantle never comes in contact with the crust. ... 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.

Answer 2

Answer:

upper crust : The Upper Crust (rock band), a Boston-based hard rock band. Crust (geology), the earth's (or another body's) geological solid outer shell. The upper crust is the planet's surface.

lower crust : Most lower crust is less dense than the underlying mantle, but mafic lowermost crust could be unstable and likely delaminates beneath rifts and arcs. ... As a result of this refining and differentiation process, such relatively felsic rocks could form much of Earth's lower crust.
