7.2: Changes to Earth 3 Dimensions & Progressions

Unit 3

matter cycling that create igneous, sedimentary, and metamorphic rocks. Emphasize the processes of melting, crystallization, weathering, deposition, sedimentation, and deformation, which act together to form minerals and rocks. (MS-ESS2-1)

CONCEPTS

SKILLS

● RockCycle ● Relationship between energy fow and cycling of matter ● Creation of different types of rocks ● Weathering and erosion ● Mineral formation

● Develop a model

LEARNING PROGRESSIONS

● Earth’s processes are a results of energy fowing and matter cycling ● Energy for the rock cycle comes from Earth’s hot interior and from the Sun. ● Cycling of matter occurs because of chemical and physical changes. ● Changes lead to mineral formation ● Cycling of matter has shaped Earth’s history

VOCABULARY

● Matter Cycling ● Energy Flow ● Igneous ● Sedimentary ● Metamorphic ● Melting

● Crystallization ● Weathering ● Erosion ● Sedimentation

● Deposition ● Minerals ● Heat Energy ● Atmosphere

POSSIBLE PHENOMENA ● A clay fower pot left out over the winter breaks into small pieces. ● Photographs of specifc Hoodoos in Bryce National Park in Utah show signifcant changes in the size of these formations over the past 100 years. ● Large arches in rock formations can be seen in Arches National Park in Utah. ● Not all rocks weather at the same rate. ● The rocks in Farmington Canyon have unusual “ribbons” or bands. ● There are big HUGE boulders scattered all over the mouth of Little Cottonwood Canyon. END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ● I can use a rock cycle model to describe the relationship between energy fow and matter cycling onEarth. ○ Language Supports ■ Nouns to support claim (cycling, energy, weather, rain, snow, wind) ■ Connectors to link clauses (as a result of, therefore, to be more precise, instead,
