Step 2: Find the main drain line outside of your home. Most homes have a main drain line and a secondary drain line.
Basalt is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes, so it's one kind of igneous rock. When the lava cools quickly, it turns into basalt. Usually basalt is black or gray. Basalt is a mixture of feldspar and pyroxene, a rock made mainly of silica and oxygen.hen the lava cools quickly, it turns into basalt.

The two best-known igneous rock types are basalt and granite, which have distinctly different compositions and textures. Basalt is the dark, fine-grained stuff of many lava flows and magma intrusions. Its dark minerals are rich in magnesium (Mg) and iron (Fe), hence basalt is called a mafic rock.So basalt is mafic and either extrusive or intrusive.Granite is the light, coarse-grained rock formed at depth and exposed after deep erosion.he main thing about igneous rocks is that they were once hot enough to melt. The following traits are all related to that. 1  Because their mineral grains grew together tightly as the melt cooled, they are relatively strong rocks. 2  They're made of primary minerals that are mostly black, white or gray.
