If you could speed up time, you would see rocks cycling from within the planet. Like a well-oiled machine, rocks are igneous, sedimentary and metamorphic.
What Do Meteorologists Do?
Meteorologists partake in weather prediction. They understand atmospheric chemistry and physics and how they relate to weather and climate patterns.
Chemical Weathering: Hydrolysis, Oxidation and Acidic Reactions
Chemical weathering is the process of transforming a rock’s composition through chemical reactions (by dissolving or converting them into other minerals)
