The Earth's Formation Preveiw

Welcome, my name is Mary Kathleen. Through out science class this year, I've have expanded my knowledge of the Earth's formation. Through this blog, I will be teaching you. Topics I will cover are how the Earth formed from a cloud made of dust and gas so that modern life could form. Also, how the ozone formed, reforms, what it does, and how it's important to modern life. UV radiation and the health affects it has on humans will be covered too, so come and discover our wonderful world.
