The four layers typically refer to the layers of the Earth: the crust, mantle, outer core, and inner core. The crust is the thin outer layer, the mantle is a thick, semi-solid layer beneath the crust, the outer core is liquid and composed mainly of iron and nickel, and the inner core is solid, also made primarily of iron and nickel. These layers vary in composition, state, and temperature, contributing to geological processes such as plate tectonics and volcanic activity.

What are the layers of sandstone called?
The layers of any sedimentary rock are called strata.
Which variable is used to separate the atmosphere into four layers?
The variable that is used to separate the atmosphere into four layers is temperature. The four layers are the troposphere, stratosphere, mesosphere, and thermosphere, and each layer is defined by changes in temperature with altitude.
The four layers of earth atmosphere from lowest to highest are what?
troposphere, stratosphere, mesosphere and thermosphere
What separates the four layers of earth?
The four layers of the Earth are the crust, mantle, outer core, and inner core. These layers are differentiated by their composition, temperature, and physical properties. For example, the crust is made up of solid rocks, while the mantle is composed of molten rock called magma. The outer core is liquid iron and nickel, while the inner core is solid due to extreme pressure.
What is it called when lower layers are pressed together by upper layers on a rock?
