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 and describe the processes that cause rapid or slow changes in Earth's surface.
2.A.2.a. Identify and describe events such as tornadoes, hurricanes, volcanic eruptions, earthquakes, and flooding which change surface features rapidly.
2.A.2.c. Cite examples that demonstrate how the natural agents of wind, water, and ice produce snow changes on the Earth's surface such as carving out deep canyons and building up sand dunes.
2.A.3. Materials and Processes That Shape A Planet: Explain how rock is formed from combinations of different minerals and that smaller rocks come from the breakage and weathering of bedrock (solid rock underlying soil components) and larger rocks; soil is made partly from weathered rock, partly from plant remains-and also contains many living organisms.
2.A.3.a. Observe and classify a collection of minerals based on their physical properties: Color; Luster; Hardness; Streak.
2.A.3.b. Identify components of a variety of rocks and compare the physical properties of rocks with those of minerals to note major differences.
2.A.3.c. Describe ways that the following processes contribute to changes always occurring to the Earth's surface: Erosion; Transport; Deposit.
MD.6.0. Environmental Science: Students will use scientific skills and processes to explain the interactions of environmental factors (living and non-living) and analyze their impact from a local to a global perspective.
6.A.1. Natural Resources and Human Needs: Recognize and explain how renewable and nonrenewable natural resources found in Maryland are used by humans to meet basic needs.
6.A.1.c. Describe how humans use nonrenewable natural resources, such as oil, coal, natural gas, minerals, including metals
