Is sill a type of lava flow?
A Sill is formed when a fluid rock (usually magma but it can be mud or salt) is squeezed in between the layers (usually horizontal) of older rocks before it solidifies in place. A Dike or Dyke is the opposite, here the fluid rock penetrates across the layering of the older rocks. Logically to get the material to form a Sill there must be an accompanying feeder Dyke.
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 type of feature can form when magma hardens between horizontal layers of rock?
A concordant intrusive igneous feature like a sill can form when magma hardens between horizontal layers of rock. Sills are tabular bodies that are parallel to the surrounding rock layers.
What forms when magma flows horizontally along rock layers?
When magma flows horizontally along rock layers, it can form a feature called a sill. Sills are tabular igneous intrusions that are parallel to the surrounding rock layers. They are typically formed when magma is injected between existing rock layers and cools and solidifies underground.
What is a slab of rock when magma squeezes between layers of rock?
sill
What is magma sill?
A magma sill is a planar sheet of magma which is parallel to the surrounding rock.
What is the geologic term for a tabular body of igneous rock that is parallel to the surrounding rock layers?
It's called a concordant igneous intrusion, or a sill.
A sheet of volcanic rock that protrudes into the surrounding layers of rock?
It's called a volcanic sill.

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.
What is an intrusive igneous rock body that is tabular and concordant?
A sill is an intrusive igneous rock body that is tabular and concordant, meaning it is parallel to the layering of the surrounding rock. Sills form when magma is injected between existing rock layers and solidifies underground.
What is a horizontal intrusive igneous body that forms between sedimentary rock layers?
A sill is a horizontal intrusive igneous body that forms between sedimentary rock layers. Sills are formed when magma intrudes parallel to the layering of the surrounding rocks and solidifies underground.
Intrusive igneous rock body that is tabular and concordant?
A sill is a type of intrusive igneous rock body that is tabular and concordant, meaning it is parallel to the layering of the surrounding rock. Sills are formed when magma is injected into existing rock layers and solidifies underground. They are often found in sedimentary rock formations.

When magma flows horizontally along rock layers, it can form a feature called a sill. Sills are tabular igneous intrusions that are parallel to the surrounding rock layers. They are typically formed when magma is injected between existing rock layers and cools and solidifies underground.
In geology what is the difference between a sill and a dyke?
Both of these are called igneous intrusions. They form when liquid magma forces its way into cracks in existing rocks and sets. If the resulting band of rock is basically vertical it is called a dyke, and if it is more horizontal it is a sill.
