How much helium is in the Earth's crust?
Helium is present in the Earth's crust, mainly sourced from the decay of radioactive elements such as uranium and thorium. The concentration of helium in the Earth's crust is estimated to be around 8 parts per million.
Ocean crust dives below continental crust because?
Ocean crust is denser
Why the crust is thinner than the ocean floor?
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
Crust under the ocean is called?
Crust under the oceans is called oceanic crust.
What is ocean crust?
it is basalt or oceonic crust
What is the crust beneath the ocean?
Oceanic Crust
What crust supports the ocean?
Oceanic crust
What crust makes up the ocean floor?
The ocean floor is mainly composed of basaltic crust known as oceanic crust. This crust is thinner and denser than continental crust and is formed through volcanic activity at mid-ocean ridges.
What is the ocean crust?
Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.
What The ocean crust is?
Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.
What is the ocean's crust?
Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.
Ocean crust is formed where in the ocean?
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).
