Descripción
You grow, plants grow, and yes—rocks grow too! They just grow very slowly.The earth is made up of different rocky plates, kind of like a big jigsaw puzzle. Together, all of this rocky jigsaw puzzle is called the lithosphere. Plate tectonics is the study of these rocky tectonic plates and how they move and change. Plates move around in different ways. Sometimes they push together at a convergent boundary. At these boundaries, volcanoes and mountains form as two chunks of rock push together. At transform boundaries, the plates slide past each other. Sometimes the sliding isn’t very smooth, and earthquakes happen. At divergent boundaries like mid-ocean ridges, the plates move away from each other and new rock oozes up from underneath, adding to the sea floor.In this experiment, you’re going to model what happens when the ocean floor spreads.
