Our photographic evidence from both plate boundaries and non-plate boundaries is really helping us see why the landscape of the Earth is just so different. We noticed some patterns--like where plates come towards each other, we have raised land, like mountains or cliffs (even in water). We also see how the land can split or crack, where plates seem to be moving away from one another.
Regardless of all these differing landscapes, we see lots of different coverings at these locations--pure rock, water, trees, grass, soil, etc. Digging deeper, we realize that all of these places, at different depths, contain something called bedrock. We pulled out some samples of bedrock to help us better understand more about plates. Bedrock is certainly hard, but it has different densities and colors. All this plate talk is making us think deeper about plates...like what must they really look like...how do they differ...how does this impact the earthquakes that happen...
