Oceanic crust gets subducted into the mantle.
Oceanic crust is usually destroyed by subduction. This occurs when one tectonic plate, typically consisting of denser oceanic crust, is forced beneath another plate, often continental crust. As the oceanic plate subducts into the mantle, it melts and is recycled, leading to geological phenomena such as volcanic activity and the formation of deep ocean trenches.
The Earth's crust is part of the lithosphere, which includes the crust and upper mantle. The lithosphere is a rigid layer that sits on top of the asthenosphere, a partially molten layer beneath it.
It when plates colliding and making the volcanos also when the earths crust is open and the mantle or lava comes out,
The process is called the rock cycle. It involves the continuous transformation of rocks through processes such as weathering, erosion, deposition, melting, and cooling in the Earth's crust and mantle over millions of years. These processes result in the formation of different types of rocks, including sedimentary, igneous, and metamorphic rocks.
Lithosphere-- it includes the uppermost part of the mantle and the crust. Lithos is derived from the Latin root meaning "of Earth".
A subduction zone is the plate boundary where old and heavy oceanic crust sinks into the mantle. At subduction zones, oceanic crust is forced beneath another tectonic plate, typically a continental plate, due to differences in density. This process can lead to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.
The middle mantle, also known as the transition zone, is composed of dense silicate minerals such as bridgmanite, ringwoodite, and perovskite. These minerals can withstand high pressure and temperatures found in this region of Earth's mantle.
No atmosphere at all the way we would think of it. It is not a complete vacuum though. Among other things there of gases from radioactive decay within the crust and mantle.
The lithosphere is composed of the oceanic and continental crusts, along with the attached hard, brittle rock of the uppermost mantle.
The main driving forces of plate motion are mantle convection currents and ridge push. Mantle convection currents are caused by the heat generated from the core creating movement in the mantle. Ridge push occurs at mid-ocean ridges where new crust is formed and pushes older crust away. These currents create the movement of tectonic plates on the Earth's surface.
If you have the owner's manual, it usually says what kind of oil you need in there.
Geologists would study the Earth's layers. They investigate the composition, structure, and processes of the Earth's crust, mantle, and core to understand its history and behavior.
