The process of sedimentary rock?
Layers of sediment are piled on top of each other, and the top layers compress the lower layers into rock.
What causes sediment and rock to move to lower elevations through time?
SUNLIGHT causes sediment rocks to move to lower elevations through time.
Air moves from where pressure is higher to lower or lower to higher?
Higher to lower.
What is it called when lower layers are pressed together by upper layers on a rock?
Compaction.
How are glaciers formed?
A glacier forms as layers of snow build up. The weight from the upper layers of snow pack down the lower layers until the lower layers become very hard and form ice.
Sediment forms layers pressure from water and top layers over thousands of years cause lower layers to stick together and to form what?
Sedimentary rocks
Are older fossils found in higher layers of earth or lower layers?
lower0000
What is the process in which layer upon layer of sediment builds up and pressure from the upper layers causes the lower layers to stick together and form solid rock?
Lithification.

The process in which pressure from the upper layers of sediment pushes down on the lower layers causing the sediments to stick together and form solid rock.?
compaction or cementation, but im pretty sure it is comoaction.
