This week we are talking about weathering, the process that breaks down rock at Earth's surface. There are all kinds of things that contribute to weathering like ice, rain, heat and the amounts of oxygen and carbon dioxide in the atmosphere.
We are exploring the effects of mechanical and chemical weathering on limestone in our Rock Shake lab. Check out the video and see if you can see the difference between the two samples.
