What is a hardened layer in a volcano?
As lava cools, it hardens and forms a thick layer of rock. These rocks are known as igneous rocks. An example of an igneous rock is pumice, which is used in spa treatments to soften feet.
What one of the following is not a intrusive igneous body?
An intrusive igneous body is formed from magma that cools and solidifies beneath the Earth's surface. Common examples include plutons, batholiths, and sills. However, a volcanic eruption, which involves the extrusion of lava onto the surface, is not an intrusive igneous body.
What clues tells geologists how extrusions are formed?
I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.
How can the geologist determine the age of the fossil if the geologist finds a fossil in a layer of sedimentary rock that lies in between 2 igneous extrusions?
The geologist will most likely take samples of the two lavas forming the igneous intrusions and use radiometric dating techniques to find their ages. He then would know that the age of the sedimentary rock was somewhere between the two. He may also look for (index) fossils within the sedimentary rock which may also give him an indication of the age of the sediment.
Extrusion in a sentence?
Extrusion is a manufacturing process where material is pushed through a die to create a specific shape or profile.
What is a body of extrusive igneous rock called?
The answer to this ? is extrusion
What tells geologists how extrusion forms?
I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.
How does the age of an igneous extrusion compare with the rock into which it was extruded?
An igneous intrusion is younger than the rock into which it intruded.

How extrusion forms?
An extrusion is an igneous rock layer formed when lava flows onto Earth's surface and hardens. Extrusions are always younger than the rocks below it.
What is a hardened layer in a volcano?
As lava cools, it hardens and forms a thick layer of rock. These rocks are known as igneous rocks. An example of an igneous rock is pumice, which is used in spa treatments to soften feet.
How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?
If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.
When magma rises what geological formation can result?
If it has broken through the Earth's crust then it would be a igneous extrusion and a volcano can form. If it hasn't complete broke through the crust it would be a igneous intrusion. Depending if the intrusion was concordant or discordant with the bedding planes it would be either a sill or a dyke.
What type of area granite and basalt rocks found in?
Principally and respectively they are the main continental and oceanic crust rocks of the Earth. They will also appear on the surface as igneous rocks by intrusion or extrusion (volcanism).
When was The Mary-Sue Extrusion created?
The Mary-Sue Extrusion was created in 1999.
When was The Lepore Extrusion created?
The Lepore Extrusion was created on 2006-10-17.
