What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers
What kind of rock is an intrusion made of?
An intrusion is a mass of igneous rock that forms when melted rock moves into cracks in rock layers and then cools.
What forms when magma flows horizontally along rock layers?
A form of igneous intrusion known as a Sil.
What is an intrusion in science terms?
Intrusive is a term that applies to igneous rocks that form from magma underground such as granite.
What is a igneous extrusion?
Lava that hardens on the surface, and are younger than the rock layers below.
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.
What are the relative ages of igneous intrusion and overlying sedimentary rock layers that dome upward?
The intrusion is younger than the overlying sedimentary rock.
If a dike is present within a rock outcrop what is its age relationship with the other rock layers?
Any igneous dike or intrusion is younger that the surrounding rock layers.
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.

Is an intrusion younger than its surrouding rock layers?
An intrusion is younger than its surrounding rock layers. An intrusion needs another rock to cut through it, which is referred to as a cross-cutting relationship.
What kind of rock is an intrusion made of?
An intrusion is a mass of igneous rock that forms when melted rock moves into cracks in rock layers and then cools.
What are 3 examples of scientific law?
1) The Law of Original Horizontatlity: assumes that sedimentary rocks and some extrusive igneous rocks form inhorizontal layers parallel to Earth's surface.2) The Law of Superposition: The layer on top is the younger than the layer beneath it andvise versa3) TheLaw of Intrusion: When magma intrudes or cuts theough, the formed igneous rocks is the youngest.
What forms when magma flows horizontally along rock layers?
A form of igneous intrusion known as a Sil.
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.
