refers to changes in ocean water level across the entire world.

Changes are due to large-scale alterations in the volume of water in the world's oceans and the shape of the ocean basins themselves.

glaciers are included!!! If glaciers melt, eustatic sea level rises and vice versa.

Underwater Ridges can cause an increase in sea level when they themselves grow larger.

Dependent on the balance between glaciation, subsidence, and sediment supply

continental margins, due to the warping downward because of massive loads of sediments that become compressed, sinking lower relative to a constant sea level, raising sea level.

Downward warping of crust creates accommodation space = sea level rise

when there is little or no sediment supply, erosion and the effects of subsidence cause the ocean to move landward.

sediments fill basin and result in less accommodation space = sea level rise

when relative sea level rises

produce fining upward sequences of rocks 

ex: shale deposited on top of sandstone

when relative sea level drops

produce coarsening upward sequences

ex: sandstone deposited on top of shale

a body of rock defined solely on the basis of the lithology of the unit it it referred to. 

ex. sandstone or limestone facies

units defined by the fossilized flora and fauna contained within them

ex: crinoid facies

units from a particular environment of deposition

ex: marine facies

states that when depth-related depositional environments (facies) migrate laterally, the sediments of a particular environment come to lie above the sediments of an adjacent environment

sediemnts that were once laterally adjacent will be deposited in a vertical sequence.

Vertical successions of flat lying sed rocks represent facies (litho or deop) that were once laterally adjacent
