SAMUEL H. â Customer Service Representative. I began my career here at The Home Depot on October 2011 as a Customer Service Representative in Baton Rouge, LA. I seized the opportunity to relocate to the contact center in Kennesaw, GA where I am currently a Customer Service Team Lead. In this role I develop, coach, lead and motivate customer service associates.
Lava is made up of crystals, volcanic glass, and bubbles (volcanic gases). As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases. When lava erupts it is made up of a slush of crystals, liquid, and bubbles.
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. Pyroxene is what jade is before metamorphosis. Asphalt pavement made with basalt. Basalt is pretty common on Earth, and there is also a lot of basalt on the Moon, and on other planets including Mars and Venus. Like granite, basalt is a very hard rock. Because it is a common rock and so hard, people used basalt for early choppers and for grinding stones for grinding grains like millet and barley.
