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.
The lava coo ls so quickly that no crystals can form. When people make glass they melt silica rocks like sand and quartz then cool it rapidly by placing it in water. Obsidian is produced in nature in a similar way. Obsidian is usually black or a very dark green, but it can also be found in an almost clear form.
