The Earth and Earth materials, as we know them today, have developed over long periods of time, through constant change processes.
Resources cannot be aligned to this standard, browse sub-standards to find lessons.
Explain that smaller rocks come from the breaking and weathering of larger rocks and bedrock.
Distinguish between the three categories of rocks (metamorphic, igneous and sedimentary) and describe the processes that create them.
Identify minerals by their physical properties, such as color, texture and cleavage, and describe simple tests used in the identification process.
Use results from an experiment to draw conclusions about how water interacts with earth materials (e.g., percolation, erosion, frost heaves).
