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.
What else can I help you with?
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?
Geologists know that rock layers are undisturbed by examining the relationships between the different layers. If the layers are parallel and show no signs of folding, tilting, or faulting, they are likely undisturbed. Additionally, the presence of index fossils can help date the layers and determine if they have been disturbed.
What rock layers are arched upward?
Rock layers that are arched upward typically form anticlines. Anticlines are characterized by an upward curve or fold in rock layers where the oldest layers are found in the center of the fold and the youngest layers are found on the outer edges.
Which igneous feature is formed when magma is forced into layers parallel to the surrounding rock layers?
A sill is formed when magma is forced into layers parallel to the surrounding rock layers. Sills are characterized by their tabular shape and are often found intruding between rock layers.
If a dike is present within a rock outcrop what is its age relationship with the other rock layers?
The dike is younger than the rock layers it intrudes into. Dikes form when molten rock (magma) is injected into fractures in existing rock layers and then solidifies, cutting across the surrounding rock. This means that the dike is a later geological event compared to the layers it cuts through.
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.
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).
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.
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
What does it mean for rock layers that are forming?
Rock layers that are forming are stratifying.
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 is a slab of volcanic rock formed when magma squeezes between layers of rock?
A sill is a slab of volcanic rock formed when magma squeezes between layers of rock. It is typically horizontal and parallel to the surrounding rock layers. Sills are distinguishable from dikes, which cut across the rock layers.
What is a type of metamorphic rock that has parallel layers?
Foliated rock has parallel layers.
How do you use rock layers in a sentence?
Those rock layers are quite colorful.
How many layers do metamorphic layers have?
a metamorphic rock is a rock that has been changed from one rock to another by heat and/or pressure.....they amount of layers would depend on what kind of rock.....all rocks have a different amount of layers sorry
