Objective 36 Students will provide the key pieces of evidence that supported the Theory of Continental Drift. Objective 37 Students will know the core vocabulary related to the Dynamic Earth Unit. Objective 38 Students will be able to identify the major layers of the earth and describe their characteristics. Objective 39 Students will be able to provide the mechanism for plate tectonics. Objective 40 Students will be able to provide evidence for sea-floor spreading. Specifically: The oceanic crust gets progressively older, away from the Mid-Atlantic Ridge, going both east and west. The Earth’s past magnetic field has be recorded in the basalt that comprises the oceanic crust. The magnetic record on the east side of the Mid-Atlantic Ridge is a mirror image of the magnetic record on the west side of the Mid-Atlantic Ridge . Objective 41 Students will use page 5 of the E.S.R.T. to identify plate boundary types, features found at these locations, and hot spot locations. Objective 42 Using the P-S wave travel time chart and given an S or P wave, students will be able to determine the epicenter distance given a travel time, or vice versa. Objective 43 Using the P-S wave travel time chart and given both S and P wave arrival times (lag-time), students will be able to determine an epicenter distance. Objective 44 Students will describe an earthquake shadow zone. Specifically it results because: S-waves cannot travel through the liquid outer core. P-waves are refracted because their velocity increases as they move toward the center of the Earth. Objective 45 Students will know the distribution of seismic waves with respect to the shadow zone. Specifically: Up to an angle of 105 degrees, from the epicenter, both P-waves and S-waves are recorded. Neither P-waves or S-waves are recorded in the shadow zone. Only P-waves are recorded at an angle, from the epicenter, exceeding 140 degrees
