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.
Magma that hardens vertically underneath the surface will form a sill?
Yes, that's correct. Sills are igneous rock formations that form when magma is intruded horizontally between rock layers and then solidifies underground. If the magma solidifies vertically underneath the surface, it will create a sill structure.
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 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.
Describe the factors that might cause magma to form a laccolith instead of a sill?
A laccolith forms when magma is injected into a horizontal crack in the rock layers, causing the overlying rock to arch upwards. This is influenced by factors such as the viscosity of the magma, the amount of pressure exerted, and the density contrast between the magma and surrounding rock. If the magma is less fluid and exerts greater pressure, it is more likely to form a laccolith instead of a sill, which forms when magma intrudes parallel to the rock layers.
What is magma sill?
A magma sill is a planar sheet of magma which is parallel to the surrounding rock.

What type of feature can form when magma hardens horizontal layers of rock?
Sill (D)
What is magma in a sill which pushes up to form a rock dome called?
The magma in a sill that pushes up to form a dome-shaped rock structure is called laccolith. Laccoliths form when magma intrudes between layers of sedimentary rock and causes the overlying rocks to arch upwards, resulting in a dome-like structure.
What are the factors that might cause magma to form a laccolith instead of a sill?

Picture of volcano sill?
A sill is an intrusive body of magma that pushes its way between layers of sediments.

What magma hardens in a horizontal crack?
Commonly referred to as a sill.
Slab that forms when magma forces itself across rock layers?
The slab of volcanic rock that is formed when magma forces itself across rock layers is called a dike. This will eventually build into mountains.
