How does earths crust respond to addition and subtraction of mass?
When mass is added to Earth's crust, it causes the crust to subside and sink due to the increased weight. Conversely, when mass is removed from the crust, it can rebound and rise due to the decreased load. This process is known as isostatic adjustment and can result in changes in the Earth's topography.
What is a special feature of earths crust?
One special feature of Earth's crust is that it is divided into tectonic plates that float and move on the semi-fluid upper mantle. This movement causes earthquakes, volcanoes, and the formation of mountain ranges.
What is another word for earths outer surface?
Another word for Earth's outer surface is "crust."
What is the name of the earths thinnest layer?
The crust, more specifically the lithosphere.
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.
Do compression and tension affect the thickness of earth's crust?
Compression and tension can indeed affect the thickness of the Earth's crust. Compression can thicken the crust by folding and faulting, while tension can cause stretching and thinning of the crust through processes like rifting and faulting. These tectonic forces play a significant role in shaping the Earth's crust over geological time scales.
What causes stress earths crust?
The movement in earths plates create powerful forces that pull or squeeze the rock in the crust.
How might a thinning of the ozone layer cause damage to the Earths environment?
Thinning of ozone causes UV to enter the earth. These UV are fatal for life on earth.
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.
A divergent boundary causes what type of stress?
A divergent boundary causes tensional stress, where tectonic plates are moving away from each other. This stress results in the stretching and thinning of the Earth's crust, leading to the formation of new crust through volcanic activity and seafloor spreading.
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.
