Earth's Dynamic Geosphere: Earthquakes Activity 5 - Lessening Earthquake Damage

Here you will find resources to help educators and their students assign earthquake intensity based on observed effects; describe the effects of passing earthquake waves; recognize the secondary effects of earthquakes; relate variations in intensity to the nature of the underlying geologic material; identify places in your community with high and low risk from earthquakes; outline steps to increase personal safety during an earthquake.

Earth's Dynamic Geosphere: Earthquakes Activity 4 - Earthquake History of Your Community

Here you will find resources to help educators and their students recognize patterns in the global distribution of earthquakes; interpret maps and research written information to determine the earthquake history of the community and region; examine correlations between faults and earthquakes on a regional and community scale; assess the likelihood of future earthquakes in the community; interpret graphical data to examine long-term trends in the number of earthquakes in the U.S.

Earth's Dynamic Geosphere: Earthquakes Activity 3 - How Big Was It?

Here you will find resources to help educators and their students rank the effects of earthquakes; map the intensity of earthquakes; interpret a map of earthquake intensity to infer the general location of the epicenter; identify geologic materials that pose special problems during earthquakes; explain how the magnitude of an earthquake is determined.

Earth's Dynamic Geosphere: Earthquakes Activity 2 - Detecting Earthquake Waves

Here you will find resources to help educators and their students construct a simple seismometer; record motion in two dimensions and also within a fixed time frame; understand how seismometers record earthquake waves; recognize P waves, S waves, and surface waves on seismograms; read a graph to determine the distance to the earthquake focus; locate the epicenter from time-distance graphs.

Earth's Dynamic Geosphere: Earthquakes Activity 1 - An Earthquake in Your Community

Here you will find resources to help educators and their students to generate and describe two types of waves; determine the relative speeds of compressional and shear waves; simulate some of the motions associated with earthquakes; infer the origin of earthquakes and the mechanism of transfer of seismic wave energy.

Earth's Dynamic Geosphere: Plate Tectonics Activity 3 - What Drives the Plates?

Here you will find resources to help educators and their students to calculate the density of liquids and compare their densities with their position in a column of liquid; observe the effects of temperature on the density of a material; examine the natural heat flow from within the Earth; understand the results of uneven heating within the Earth; and understand the causes of the movement of lithospheric plates.

Earth's Dynamic Geosphere: Plate Tectonics Activity 2 - Plate Boundaries and Interactions

Here you will find resources to help educators and their students classify and label the types of movement at plate boundaries, using a world map that shows relative plate motion; identify the distribution of plates by means of the world map of relative plate motions; describe the present plate-tectonic setting of your community and infer possible past plate-tectonic activity based on your knowledge.

Earth's Dynamic Geosphere: Plate Tectonics Activity 1 - Taking a Ride on a Lithospheric Plate

Here you will find resources to help educators and their students determine the direction and rate of the movement of positions within the plate on which your community is located, using data from GPS and a computer model; predict the position of your community in the near future, and "retrodict" its position in the recent past, by extrapolating from data already collected; recognize that the rate and direction of plate motion is not necessarily constant; describe several lines of evidence for plate motion.

Earth's Dynamic Geosphere: Volcanoes Activity 6 - Volcanic History of Your Community

Here you will find resources to help educators and their students demonstrate awareness of the knowledge used to construct geologic maps, examine and identify several common igneous rocks, identify the distribution of active volcanoes on one map and rock types on a given geologic map, recognize that volcanic rocks indicate a history of volcanic activity.
