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.

What are formed when magma cools inside earth?
Granite and other intrusive igneous rocks. Such as a sill or dyke.
What is a tabular concordant pluton?
A tabular concordant pluton is a sill.A Sill is a flat concordant pluton. And a tabular means flat, like a table or tablet. Thus a sill is a tabular concordant pluton.In fact a the wikipedia article for "sill (geology)", as of the 01:33, 19 February 2009 update by Vsmith, read " a sill is a tabular pluton that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or even along the direction of foliation in metamorphic rock." - http://en.wikipedia.org/wiki/Sill_(geology)
What is a sill in a volcano?
A sill is an intrusive body of magma that pushes its way between layers of sediments.
What are the Igneous intrusions injected between horizontal layers known as?
Igneous intrusions that are concordant (parallel to bedding planes of country rocks) are known as sills, whereas dykes cut through the bedding.
Takes place when magma intrudes rock?
It is called a dyke or dike, and could also be referred to as a discordant igneous intrusion.
What are some geology key terms?
dyke - verticall lava through a rock. sill - horizontall lava through a rock. pillow lavas - pillows sold in asda which support your gullable head as you sleep.
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 landform is created when magma squeezes between rock layers to forma hardened slab of rock?
If vertical, a dyke; if horizontal, a sill.

Magma that hardnes vertically underneath the surface will form a sill?
A sill is a tabular intrusive igneous rock body that forms when magma solidifies horizontally between layers of preexisting rock. It does not harden vertically underneath the surface. If the magma solidifies vertically underneath the surface, it would form a vertical intrusion known as a dike.
What is a sill in a volcano?
A sill is an intrusive body of magma that pushes its way between layers of sediments.
Picture of volcano sill?

An igneous intrusion that cuts across rock layers is called a?
A discordant intrusion is known as a dyke. A larger intrusion may also be a pluton or batholith, which both also cut across rock strata. A sill is an intrusion which is concordant, and goes between the strata. This does not necessarily mean that it is horizontal.
What is sills?
A sill forms by magma being forced into cracks that are parallel to rock layers and harden there. When magma flows between the layers of rock and hardens, a sill forms.
