7.2: Changes to Earth 3 Dimensions & Progressions

Unit 3

●​ Mountain ●​ Plate tectonics ●​ Continental boundary ●​ Ocean

●​ Hot spot ●​ Fault ●​ Geosphere ●​ Uplift

●​ Density ●​ Chemical composition

POSSIBLE PHENOMENA ●​ Near St. George Utah the tops of the buttes are covered with lava flow, but the valleys and ravines are covered with sand and sandstone. ●​ Throughout the Hawaiian Island there are many different beach landscapes. ●​ The old sidewalks seem to be more worn out than new sidewalks. ●​ The Colorado Plateau is a very large uplifted portion of three states and home to nine National Parks. ●​ Lake Bonneville sediments can be found on the sides of mountains throughout Utah. ●​ The Hawaiian Islands are not all the same age. ●​ People in Iceland get most of their energy from geothermal energy sources. ●​ There are many volcanoes along the western edge of North and South America. ●​ There is a pattern of a ring of volcanoes in the Pacific Ocean. ●​ Tropical plant fossils have been found in Antarctica. ●​ There is a mountain ridge in the middle of the Atlantic Ocean that is over 7,700 feet in elevation. END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ●​ I can analyze and interpret data about partners between plate tectonics and the occurrence of earthquakes and volcanoes, continental and ocean floor features. ○​ Language Supports ■​ Words to support data analysis (patterns, trends, extrapolate) ■​ Expanded noun groups to classify and add detail (energy releasing, reconfigured, plate movement caused) ■​ Express Causality (if the plates move toward each other then _____, if the plates move away from each other then_____, etc.) ●​ I can give evidence and explain how Earth's surface has changed over time. ○​ Language Supports ■​ A variety of verb groups to describe events (in the past, in the future, conditional, the history of, over the past ___ years, etc.)

DIFFERENTIATION IN ACTION

●​ Students create a model of the continental plates, and model the different boundary types that the continental plates create.
