Intrusive Igneous Rock
A Batholith or Pluton.
yes
An intrusive (plutonic) igneous rock, eg sills and batholiths.
Basalt
cooled magma
Igneous rock is formed from solidified and cooled magma or lava.
A volcano is formed when the molten magma (lava) beneath the crust is forced to the surface. Volcanic rock is lava that has cooled.
pumice
Gabbro is formed from slow cooling basaltic magma.
Yes, that is correct. A batholith is a large mass of intrusive igneous rock that forms from the solidification of magma deep beneath the Earth's surface. As the magma cools and solidifies over time, it creates a massive body of rock that can be exposed through erosion.
A divergent boundary is formed when magma rises to the surface and new crust is formed. This process occurs at mid-ocean ridges where tectonic plates move away from each other, allowing magma to fill the gap and solidify into new oceanic crust.
