Sediment layers are squeezed from above by the weight of overlying sediment, causing compaction. Compaction squeezes out air and water between the sediment particles. Minerals form as the air and water is squeezed out, cementing the particles together, and forming sedimentary rock.

How does folding change rock layers?
Most rock layers (and ALL sedimentary layers) start out flat. Folding changes the angle of lie (even to perpendicular and beyond).
How do geologist know that rock layers are undisturbed?
the way geologist know that rock layers are undisturbed is the rock layers are folded
Gaps in rock layers that develop when agents of erosion remove existing rock layers?
Gaps in rock layers that develop when agents of erosion remove existing rock layers are known as unconformities.
What is the sinking of rock layers?
the sinking of the rock layers is called subsidence
What are gaps in rock layers called?
Gaps in rock layers are called unconformities.

How can water change the shape of a rock?
Water is made of atoms,these can pound against a rock,gradually removing layers this will change it's shape.
Are Aquifers rock layers?
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
Can metamorphic rock form from sedimentary rocks?
Yes. A sedimentary rock, over time, can become buried under layers of newer rock. The heat and pressure from being in between layers of old and new rock, will change it from sedimentary to metamorphic.

Gaps in rock layers that develop when agents of erosion remove existing rock layers?
Gaps in rock layers that develop when agents of erosion remove existing rock layers are known as unconformities.
What does it mean for rock layers that are forming?
Rock layers that are forming are stratifying.
What is the sinking of rock layers?
the sinking of the rock layers is called subsidence
What do you call the layers in sedimentary rock?
Sedimentary rock layers. your welcome
How do we know if rock layers are undisturbed?
The rock layers will be easily visible.
What are the layers of a rock?
there are many layers
What are gaps in rock layers called?
Gaps in rock layers are called unconformities.
