Magma that hardens vertically underneath the surface will form a sill?
No. A sill forms when magma hardens parallel to the rock layers, which is usually horizontal. When magam hardens vertically, it forms a dike.
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 forms when magma flows horizontally along rock layers?
A form of igneous intrusion known as a Sil.
What type of feature can form when magma hardens between horizontal layers of rock?
Sill (D)
Describe the factors that might cause magma to form a laccolith instead of a sill?
Simple terms- Chemical and Physical particles
What is magma sill?
A magma sill is a planar sheet of magma which is parallel to the surrounding rock.

What is a sill in a volcano?
A sill is an intrusive body of magma that pushes its way between layers of sediments.
Does a dike form when magma forces itself between rock layers and hardens?
No, when magma forces itself BETWEEN rock layers it is called a sill. When the magma cuts THROUGH rock layers it is called a dike.
What forms when magma flows in a horizontal direction?
A Sill.
