What else can I help you with?
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
What causes stress earths crust?
The movement in earths plates create powerful forces that pull or squeeze the rock in the crust.
What type of stress causes the earths crust to become thinner?
Tension
How does stress change earths crust?
It causes it to deform - this deformation is called "strain".
What process causes Earth's crust to be continuously formed by volcanic activity?
Pressure from the earths core
Why is the earths crust always moving?
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.
What causes the pressure to increase as you go deeper below the earths crust?
Because the density of the force increases.
What is the size of the earths crust?
The Earths crust is approximately 650 km deep.
Convection currents in the earths crust causes volcanos?
No. Earth's crust does not convect. Convection in the mantle, however can create hot spots and rifting, which can lead tot he formation of volcanoes.
What is under the earths surface and in the earths crust?
mantle
Why is the stress the earths crust?
The earth's crust is not stress
What are volcanoes and what causes them?
a volcano is a rupture or opening in the earths crust. caused by convergent (coming together) or divergent (moving apart) plates
