It was formed from slow cooling., How do intrusive rocks form? Lava cools slowly outside a volcano. Magma cools slowly inside a volcano. Molten material is cooled quickly by water. Magma is ejected into the air and cools slowly., An igneous rock has a large amount of feldspar. Feldspar can be used to classify the rock based on which characteristic?
