Are only sedimentary rocks used for relative age determination?
No, igneous rocks can be used in this way based on the fact that an igneous intrusion will be younger than the material through which it passes. This is part of the principle of cross cutting relationships.
What are two ways sedimentary and igneous rocks can be changed into metamorphic rocks?
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
Intrusive igneous bodies that cut across existing sedimentary beds are said to be?
Intrusive igneous bodies that cut across existing sedimentary beds are said to be discordant. An example of a discordant intrusion is a batholith.
How does igneous intrusion end up as a hill?
Basically, igneous intrusion involves the solidifying of magma when it cools in the crust of the Earth. When magma rises through the crust, it intrudes into the existing sedimentary rock layers and forms a hill. The surounding rock may be more prone to erosion and wear away leaving the intrusion jutting above the (eroded) surroundings.
What are crystals igneous sedimentary or metamorphic?
its igneous and sedimentary and metamorphic
What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers
Where is igneous rock in magma intrusion into sedimentary rock?
In dikes and sills.

What is the age of an igneous intrusion in relation to the sedimentary rock layers it passes through?
It is younger than them.
What is the age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passed?
It is younger.
What is the The age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passes?
It is younger.
Why portions of the sedimentary rock layers have the symbol for contact metamorphism?
the rock layers were eroded at the interface between the igneous intrusion and the sedimentary rocks.

What geologic law is applied if an igneous intrusion is observed through a layer of sedimentary rock?
law of crosscutting relationships.
How can an igneous or sedimentary rock become metamorphic?
In simple terms...undergoing additional heat and pressure from a more recent igneous intrusion which change the structure and minerology.
