Where does all the force come from that squeezes sediments together to form sedimentary rocks?
The force is created by the self weight of the overlying material.
When sediments are squeezed together by the weight of sediments and rocks on top of them what is it called?

What is the prossess where grains are pressed together by the weight of sediments above?
The process where grains are pressed together by the weight of sediments above is called compaction. It is one of the processes of lithification.
The process by which dissolved minerals crystallize and glue particles of sediment together into one mass?
The particles in the sediments are cemented as pressure squeezes out water. The dissolved minerals in the water, usually silica or calcite, then become solid (crystallize), tying the particles together.
What presses sediments together?
Usually weight from above, whether from a body of water or from additional sediments.
Where does all the force come from to squeeze sediments together to form sedimentary rocks?
The main force is weight of overlying rocks , called overburden, which puts overburden pressure on sediments and make them compress and compacts
What is the process in which the volume and porosity of a sediment is decreased by the weight of overlying sediments?
The process is called compaction.

Where did sedimentany rock come from?
Sediments (sand, clay, boulders etc) are derived from the erosion of preexisting rocks by snow, ice, water and wind. Eventually these sediments settle and are covered by more sediments. As the weight of overlying sediments builds up the pressure and minerals dissolved in and carried by groundwater cement the sediment particles together to form a new rock layer. This new rock is called a sedimentary rock.
What will happen to the thickness of a bed of sediment when it is compacted and why?
As fluids and spaces between particles are squeezed out by the weight of overlying sediments, the particles become closer to each other, thus flattening the thickness of the strata.

Which type of rock forms due to the weight of overlying rocks?
Metamorphic
What generates the pressure required for metamorphism?
Pressure from weight of overlying rock.
Which type of rock forms due to weight of the overlying rocks?
Metamorphic

Metamorphic
What is the consequence of removing water from aquifers?
Aquifers can't support the weight of overlying structures.
