SEVENTH AND EIGHTH GRADES
CHANGING EARTH/EARTH SYSTEM
Benchmarks
ES.8.E Describe the
processes that contribute to
the continuous changing of
Earth’s surface (e.g.,
earthquakes, volcanic
eruptions, erosion,
mountain building and
lithospheric plate
movements).
Grade Level Indicators
and Sub-Indicators
a.8.9 Describe the interior structure of Earth and Earth’s crust as divided into tectonic plates riding on
top of the slow moving currents of magma in the mantle.
a.8.10 Explain that most major geological events (e.g., earthquakes, volcanic eruptions, hot spots and
mountain building) result from plate motion.

a.8.11 Use models to analyze the size and shape of Earth, its surface and its interior (e.g., globes,
topographic maps, satellite images).
a.8.12 Explain that some processes involved in the rock cycle are directly related to the thermal energy
and forces in the mantle that drive plate motions.
a.8.13 Describe how landforms are created through a combination of destructive (e.g., weathering and
erosion) and constructive processes (e.g., crustal deformation, volcanic eruptions and the deposition of
sediment).
a.8.14 Explain that folding, faulting and uplifting can rearrange the rock layers so the youngest is not
always found on top.
a.8.15 Illustrate how the three primary types of plate boundaries (transform, divergent and convergent)
cause different landforms (e.g., mountains, volcanoes, ocean trenches).
-----------------------PS.8.D Describe that
energy takes many forms,
some forms represent
kinetic energy and some
forms represent potential
energy; and during energy
transformations the total
amount of energy remains
constant.
-------------------------------------------------------------------------------------c.8.4 Demonstrate that waves transfer energy.
c.8.5 Demonstrate that vibrations in materials may produce waves that spread away from the source in
all directions (e.g., earthquake waves, sound waves).
Sub-Indicators:
 Compare and contrast convection currents in magma, air and water.
 Make a sketch of the various layers of the earth.
 Analyze the theory of plate tectonics through investigation of the break-up of Pangaea.
 Create a sketch or map of the stages of the break-up of Pangaea.
 Read topographic maps.

Infer geological history from rocks.
Describe the effects of natural changes (e.g., earthquakes, volcanic eruptions, erosion, etc.) on
human activities.
Implement maps, diagrams, and common situations to determine how earth-changing processes are
reflected in the landforms of the earth’s surface.
Compare and contrast the processes of plate tectonics (e.g., volcanism, earthquakes, rifting,
mountain building, etc.).
Make maps and diagrams of the various landforms (e.g., mountains, valleys, plateaus, etc.).
Investigate relationships between volcanoes and earthquakes to land formation and land
deformation.
Know three types of waves (primary, secondary, surface).
