What is the difference between the mantle and outer core of the Earth?

There are differences in chemistry (the mantle is mainly ultramafic rock--the outer core is metallic), in phase (the mantle is predominately solid--the outer core is liquid), in depth (the outer core is closer to the center of the Earth), and in density (the outer core is more dense).


What is the process in which layers of rock flake off a larger rock as a result of weathering?

The process in which layers of rock flake off a larger rock as a result of weathering is called exfoliation. This occurs due to the expansion and contraction of rock layers in response to changes in temperature, causing the outer layers to break off. Over time, repeated cycles of expansion and contraction lead to the gradual exfoliation of the rock's outer layers.


What type of rock is found in the outer core?

The outer core is predominantly made up of liquid iron and nickel, as well as some lighter elements like sulfur and oxygen. This molten material gives rise to Earth's magnetic field through convective currents. It is not composed of rock in the traditional sense, as it exists in a liquid state due to the high temperature and pressure found in the Earth's core.


The core is Earth's outer skin of solid rock. True or False?

False, the crust is Earth's outer skin of rock. The core is a body of metal at earth's center.


Exfoliated domes are made out of what type of rock?

Exfoliated domes are typically made out of granite, a type of igneous rock. This rock type is resilient and can withstand the process of exfoliation, which involves the outer layers of the rock peeling away due to pressure release.
