Precariously sharing the same orbits, these bodies hurtled into one another, with the smaller one breaking up entirely to form a ring around the world. Climate change affects all regions around the world. Estimated Class Time for the Exploration: 2-3, 45 minute class periods, The elaboration section of the 5E method of instruction is intended to give students choice on how they can prove mastery of the concept. Lab and Safet, This catastrophic events activity will have your students critically writing and drawing about the impact of catastrophic events on an ecosystem. Although no one knows for sure, the most commonly excepted explanation of the Moons formation is the giant impact hypothesis. Because of all these interconnections, it is important to study catastrophes all together, instead of in isolation. That process splits water into molecular hydrogen and oxygen. And these all add to the ongoing risk from natural disasters like asteroids and volcanoes, some combination of which probably killed off the dinosaurs. Estimated Class Time for the Elaboration:1, 45 minute class period. The young solar system was a volatile place where the planets formed from a proto-planetary disk. The meanest drought looks different in the rural than in urban areas. Please check out other products in my store. These effects depend on the characteristics of the seismic event that created the tsunami, its magnitude, the gap from its point of origin, and arrangement on the bathymetry (depth of water in oceans).
