Any molten rock that has not reached the surface is called magma. It is made when two tectonic plates collide and one edge of a plate is forced underneath the other, and pushed closer to the center of the earth where it heats up, and melts down.

it's not batholith ethier.
I may be wrong, but i think perhaps sill.

Which type of intrusive feature forms when magma is injected into fractures cutting across preexisting rock layers?
sill
What is a sheet like body that cuts across rock layers and is produced when magma is injected into a fraction is called?
A dike I got it right on a test
What kind of rock forms from magma?
igneous rock
What are older rocks that lie under younger rocks called?
You may be referring to an "outlier" which is an area of older rocks surrounded by younger ones due to faulting and erosion removing layers of younger rocks and forcing older ones up into them. You may also potentially be referring to a xenolith. This is a fragment of older material that has not melted that is trapped within lava or other younger igneous material.
When molten rock is below ground is called?
Magma
What is Magma injected into older rock?
That is known as an "intrusion". The magma (lava) is forced under pressure into cracks and fissures within the older rock. There are some good examples of this type of formation in Yellowstone caldera.

Are sills tabular discordant bodies that are produced when magma is injected into fractures?
No, they are a tabular igneous body that was intruded parallel to the layering of preexisting rock.
What kind of rock forms from magma?
igneous rock
Is magma a weathered rock?
No. Magma is molten rock underground.
How is magma and igneous rocks related?
Magma is molten rock, and igneous rock is cooled magma.
How does magma create rock?
Magma is molten rock. It becomes rock by cooling and hardening.
Which type of rock forms from magma?
magma is a mixture of several different types of rock.
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.
