Crust
Earth's layers were formed through a process called differentiation, which occurred during the early stages of the planet's formation. As rocks melted due to intense heat from radioactive decay and impacts, denser materials sank towards the center to form the core, while lighter materials rose to the surface to form the crust and mantle. This process created distinct layers based on the density of the materials.
a fault
The earth's atmosphere is very old. It was formed when earth was formed.
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.

Natural gas is formed from organic materials deep in earths soil heating over geological time.
how do geologists think earths atmosphere is formed
Many elements and materials which could not have been produced any other way (like diamonds).
Diamonds are usually formed in the mantle.
intrusive rocks are formed within the earths surface from magma. extrusive rocks are formed from lava outside of earths surface
It was about 4 billion years ago, that the Earths oceans formed
A sedimentary rock is formed by the gradual and contineous accumulation, stratification, compactation, sedimentation, cementation, and lithification of transported and deposited debrises, detrituses, regoliths and other earths disintegrated materials, over a long period of time.
They were formed by the heat coming up from the earths centre
Crust
It is the result of how the earth was formed.
Crust is neither formed nor destroyed when the rate of crust formation at mid-ocean ridges equals the rate of crust destruction at subduction zones. This balance is known as isostasy and helps maintain the overall thickness of the Earth's crust.
