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 intrusion forrm
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;)😊
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.

yes
yes they can they did it with aborinies
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.
ummm....?
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.
geologists
* landforms are natral features of the earth
Extrusion provides geologists with clues about the type of lava that erupted from a volcano, the direction of lava flow, the age of the eruption based on the surrounding rock layers, and potential past volcanic activity in the region. It can also give insight into the geological processes that have shaped the landscape over time.
