What is larger sill dike laccolith or batholith?
A batholith is the largest intrusive igneous formation, made up of a large mass of granite or granitic rocks, that covers an area of tens to hundreds of square kilometers. Sill, dike, and laccolith are all smaller intrusive igneous formations. Laccolith is larger than sill or dike, with a typically flat base and arched roof, intruding between sedimentary rock layers.
What does magma pushed into a thick sill form?
When magma is pushed into a thick sill, it solidifies underground to form a layer of igneous rock called a dike. Dikes typically cut across existing rock layers, creating a discordant intrusion. The rock that forms from the cooling magma in a dike is usually fine-grained due to the rapid cooling process underground.
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 type of rock is a laccolith?
A laccolith is a type of igneous rock formation that is created when magma intrudes between layers of sedimentary rock, causing the overlying layers to arch upward. It is classified as an intrusive igneous rock.
What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers

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 is near the surface intrusive igneous rock body that results from local inflation of a horizontal sill?
This is known as a laccolith.

Do laccolith features occur when volcano lava cools at the surface?
No. A laccolith is an intrusive feature.

A laccolith is an igneous formation between two sedimentary layers
Picture of volcano sill?
A sill is an intrusive body of magma that pushes its way between layers of sediments.
What is the difference between a sole plate and a sill plate in construction?
In construction, a sole plate is the bottom horizontal member of a wall frame that sits directly on the foundation, while a sill plate is the bottom horizontal member of a window or door frame that sits on top of the foundation.
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.
