How can you tell the difference between an intrusion and extrusion if there is a layer of sandstone on top?
An intrusion is formed when magma pushes into surrounding rock layers, creating intrusive features like veins or sills, which would be visible beneath the layer of sandstone. In contrast, an extrusion occurs when magma is ejected onto the surface as lava, forming extrusive features like lava flows or volcanic cones above the sandstone layer. The presence of different types of volcanic features would help distinguish between an intrusion and an extrusion in this scenario.
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.
Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?
Magma that forces its way into rocks and hardens is called intrusion.
Can geologists use radioactive dating to find the absolute ages of extrusion and intrusion?
Yes, geologists can use radioactive dating to determine the absolute ages of extrusion (e.g., volcanic rock deposited on the Earth's surface) and intrusion (e.g., molten rock that has moved into existing rock formations). By analyzing the decay of radioactive isotopes within the rocks, geologists can calculate the age of these geological events.
What clue tells geologists intrusion?
A clue that tells geologists about an intrusion is the relationship between the rock layers. An intrusion is younger than the surrounding rocks it cuts through, so if the intrusion appears to cut across existing layers, it is likely an intrusion. Additionally, the mineral composition and texture of the intrusion can differ from the surrounding rocks, providing further evidence of an intrusion.
What do an intrusion and an extrusion tell us about the rock layers?
(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.

What is the different between intrusion and extrusion?
What is the difference between intrusive and intrusive.
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 ;)
Can geologists use radioactive dating to find the absolute ages of extrusion or the intrusion?
yes they can they did it with aborinies
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.
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.

What clues does extrusion tell geologists?
Geologists study where intrusion and extrusion formed in relation to other rock layers. This helps geologists understand the relative ages of the different types of rock! Hope it helps;)😊
