CH 22.5 Earthquakes

CH 22.5 Earthquakes

Author: deirdre carney
  • Describe the causes and effects of stress in Earth's crust
  • Explain why earthquakes occur and how their energy is propagated as seismic waves
  • Explain how earthquakes are measured and how earthquake data is used to learn about Earth's interior

Relate how the theory of plate tectonics explains sea-floor spreading, subduction, and formation of mountains
Explain the mechanisms of plate movement

Nevada Science Standards

E.8.C.4 Students know the very slow movement of large crustal plates result in geological events.  E/S

E.12.C.1 Students know how successive rock strata and fossils can be used to confirm the age, history, and changing life forms of the Earth, including how this evidence is affected by the folding, breaking, and uplifting of layers. E/S 

Next Generation Science Standards

HS-ESS1-5. Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks.

HS-ESS2-1. Develop a model to illustrate how Earth’s internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features.
