when magma is squeezed into horizontals craks are called sill
It forms a sill.
An intrusion.
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.
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.
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.

An intrusion.
It's sill or batholith.
if it squeezes into a fault, its a dike, if it squeezes between horizontal layers, its a sill

Magma that hardens in a horizontal crack typically forms a thin, sheet-like intrusion called a sill. Sills are created when magma is injected parallel to the existing rock layers. As the magma cools and solidifies, it forms a horizontal layer of igneous rock within the crack.

When magma hardens inside the Earth's crust, it can form vertical columns known as dikes, and horizontal layers called sills. Dikes form when magma cuts through pre-existing rock layers, while sills are formed when magma intrudes between existing rock layers.
The magma forms sills and magma chambers.
If vertical, a dyke; if horizontal, a sill.
