The following are some rocks that I have collected from various sites in Newfoundland Labrador. Please feel free to forward a photo of your rock collection or a favorite rock, in your collection.
What type of rock is this. I think it’s Igneous Link to site in blue
Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava). When lava cools very quickly, no crystals form and the rock looks shiny and glasslike. Sometimes gas bubbles are trapped in the rock during the cooling process, leaving tiny holes and spaces in the rock.
