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 fow, 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 Pacifc 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 foor features. ○ Language Supports ■ Words to support data analysis (patterns, trends, extrapolate) ■ Expanded noun groups to classify and add detail (energy releasing, reconfgured, 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.
