What is extrusion relating to rocks?
yea
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.
Is an extrusion older or younger than the rock layer below it?
Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)
how does knowing the prefixes in- and ex- help you remember the differ-ence between an intrusion and an extrusion?

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).
What clues of extrusion tell geologists?
Geologists can identify extrusion by looking for volcanic features such as lava flows, ash deposits, and volcanic cones. The presence of volcanic rocks, such as basalt or rhyolite, can also indicate past volcanic activity associated with extrusion. Additionally, geologists may identify extrusion sites by studying the topography and landforms created by lava spreading over the surface.
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 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.
What was obsidian before it was obsidian?
It was liquid rock (magma) which solidified after an extrusion or eruption. Crustal rocks can re-dissolve into magma during subduction of oceanic crust.

When was The Mary-Sue Extrusion created?
