NSES Content Standard D
Earth and Space Science: Structure of the Earth system
Grades 5-8, page 159
The solid Earth is layered with a lithosphere; hot, convecting mantle;
and dense, metallic core.
NSES Content Standard D
Earth and Space Science: Structure of the Earth system
Grades 5-8, page 160
Lithospheric plates on the scales of continents and oceans constantly
move at rates of centimeters per year in response to movements in the mantle.
Major geological events, such as earthquakes, volcanic eruptions, and mountain
building, result from these plate motions.
NSES Content Standard F
Science in Personal and Social Perspectives: Natural hazards
Grades 5-8, page 168
Internal and external processes of the Earth system cause natural hazards,
events that change or destroy human and wildlife habitats, damage property,
and harm or kill humans. Natural hazards include earthquakes, landslides,
wildfires, volcanic eruptions, floods, storms, and even possible impacts
of asteroids.
NSES Content Standard D
Earth and Space Science: Energy in the earth system
Grades 9-12, page 189
The outward transfer of earth's internal heat drives convection circulation
in the mantle that propels the plates comprising earth's surface across
the face of the globe.
