MD.2.0. Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
2.A.2. Materials and Processes That Shape A Planet: Cite evidence to demonstrate and explain that physical weathering and chemical weathering cause changes to Earth materials.
2.A.2.c. Compare physical and chemical weathering and provide examples if changes caused in Earth materials or features by each of these processes.
2.A.4. Materials and Processes That Shape A Planet: Differentiate among sedimentary, igneous, and metamorphic rocks based upon the processes by which they are formed.
2.A.4.a. Identify and describe the processes that form sedimentary rock: Deposition; Compaction; Cementation.
2.A.4.b. Identify and describe the processes that form igneous rocks: Volcanic eruptions; Igneous intrusions.
2.A.4.c. Identify and describe the processes that form metamorphic rocks: High Temperature; Pressure.
2.A.4.d. Cite features that can be used as evidence to distinguish among the three types of rocks and relate these features to the processes that form each rock type.
2.A.4.e. Describe the processes that change one form of rock into another (rock cycle).
