Which type of rock does magma form when it hardens?
Magma forms igneous rock when it cools and hardens. Igneous rocks can be further classified as intrusive (formed below the surface) or extrusive (formed on the surface).
Magma that hardens vertically underneath the surface will form a sill?
Yes, that's correct. Sills are igneous rock formations that form when magma is intruded horizontally between rock layers and then solidifies underground. If the magma solidifies vertically underneath the surface, it will create a sill structure.
How does an Igneous rock turn into Magma?
No. If it cools as magma it will form an intrusive igneous rock. To form an extrusive igenous rock it must erupt from a volcano, where it becomes lava or pyroclastic material.
What type of feature can form when magma hardens between horizontal layers of rock?
A concordant intrusive igneous feature like a sill can form when magma hardens between horizontal layers of rock. Sills are tabular bodies that are parallel to the surrounding rock layers.
Do Volcanic necks and dikes form when magma cools and hardens into rock after reaching the surface?
No, these features form when magma cools into rocks BEFORE reaching the surface.
