Study Guide
SES1. Students will investigate the composition and formation of Earth systems, including the
Earth’s relationship to the solar system.
e. Identify the transformations and major reservoirs that make up the rock cycle,
hydrologic cycle, carbon cycle, and other important geochemical cycles.
SES2. Students will understand how plate tectonics creates certain geologic features, materials,
and hazards.
d. Associate specific plate tectonic settings with the production of particular groups of
igneous and metamorphic rocks and mineral resources.
SES3. Students will explore the actions of water, wind, ice, and gravity that create landforms
and systems of landforms (landscapes).
a. Describe how surface water and groundwater act as the major agents of physical and
chemical weathering.
b. Explain how soil results from weathering and biological processes acting on parent
rock.
c. Describe the processes and hazards associated with both sudden and gradual mass
wasting.
d. Relate the past and present actions of ice, wind, and water to landform distribution
and landscape evolution.
e. Explain the processes that transport and deposit material in terrestrial and marine
sedimentary basins, which result, over time, in sedimentary rock.

The eight tests used to help identify minerals.
Color
Crystal shape
Luster
Hardness
Streak
Cleavage
Fracture
Specific gravity
May not be useful since many minerals have the same color.
May be difficult to notice since crystals can be very small.
Describes how light reflects from a mineral; can be dull, metallic, pearly, glassy,
greasy, or silky.
Resistance to being scratched, based on Mohs’ scale of hardness.
Color of mineral’s powder when rubbed on a white tile; can be different from the
mineral color.
Ability to split along flat surfaces; especially useful in identify mica which is made of
paper thin layers.
Manner in which mineral breaks if there is no cleavage.
Density of mineral compared to water.

Examples
Igneous
Metamorphic
Sedimentary
Regional metamorphism occurs when large areas of rock are changed by heat and pressure. This can
occur when mountains are created. Examples are:
Contact metamorphism occurs when hot magma bakes rocks that come in contact with it. This affects a
smaller area than regional metamorphism. Examples are:

Draw an arrow to represent each possible transition from one rock type to another. Then label
each arrow with the process that occurs, such as “weathering” or “erosion and deposition.”
