Hello my name is Kayla and I'm going to tell you what we have been learning. Ms Crowther showed us that the world is one big jigsaw puzzle. The swirling currents in the mantle (shown in our experiment), are so powerful, that they have made cracks in the earth's crust. These cracks mean the world, with all it's countries, is broken into plates. These plates float on the mantle, and are constantly moving. Millions of years ago our land formed one big continent. Slowly the land broke apart to look like it does today.
