Build Your Bridge
is designed for middle school students. It supports California State Content
Standards for 6th grade science and National Science Education Standards
for grades 5-8.
California State Content Standards for 6th grade
Plate Tectonics and Earth's Structure
1. Plate tectonics accounts for important features
of Earth's surface and major geologic events. As a basis for understanding
- Students know evidence of
plate tectonics is derived from the fit of the continents; the location
of earthquakes, volcanoes, and midocean ridges; and the distribution
of fossils, rock types, and ancient climatic zones.
- Students know Earth is composed
of several layers: a cold, brittle lithosphere; a hot, convecting mantle;
and a dense, metallic core.
- Students know lithospheric
plates the size of continents and oceans move at rates of centimeters
per year in response to movements in the mantle.
- Students know that earthquakes
are sudden motions along breaks in the crust called faults and that
volcanoes and fissures are locations where magma reaches the surface.
- Students know major geologic
events, such as earthquakes, volcanic eruptions, and mountain building,
result from plate motions.
- Students know how to explain
major features of California geology (including mountains, faults, volcanoes)
in terms of plate tectonics.
- Students know how to determine
the epicenter of an earthquake and know that the effects of an earthquake
on any region vary, depending on the size of the earthquake, the distance
of the region from the epicenter, the local geology, and the type of
construction in the region.
