What pushes and pulles on earths crust?
Gravity.
What causes cracks in the earth's crust?
The crust is the thinnest part on the Earth.
What twists tears or pushes part of the earths crust past another?
convection currentsShear
Which formation occurs when magma pushes all the way through the exterior of the earths crust?
volcanic mountain
What is the process of deformation of the earth's crust producing oceans mountains and ocean basins?
Thermal Convection In the Earths Core Pushes the plates around bashes them into earch other over millions of years this causes the Geological effects you describe. (its a bit like if you boiled a soup and lay a few leaves on the top of it, they will move as the soup simmers beneath them)
What pushes and pulles on earths crust?
Gravity.
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.

How is an earhquake started?
An earthquake is started when two plates (which lie under the Earths surface) rub together this creates movement which then sometimes pulls/pushes at the earths surface and creates giant cracks in the earths surface... and that is how an earthquake is started.
Is A vibrating object pushes the molecules together and causes an area of compression?
true
What type of stress causes anticlines and synclines?
its the circulation of the rock and when it pushes together
What is the pressure when a solid pushes another solid?
The pushing force divided by the area of contact.
A vibrating object pushes the molecules together and causes an area of compression?
True.
How did people in 19th century think mountains were formed?
they thought the metallic plates of the earths crust rubs together and pushes the earth up
What other structures have forces acting on them?
All structures have the force of gravity and contact force, placed on earths surface. gravty pushes down with a force mass times gravity and the floor pushes up with contact force equal and oposite to this. thus everything always at all times has forces acting on them. there are other forces like kenetic friction that objects moving expierence but not all objects move thus will have static friction. when you see a bull dozer smashing a building the bulldozer cable has the force of tension.
