Earthquakes, Volcanoes and Plate Tectonics Share-a-thon 54 Files

A share-a-thon is a place where teachers can voluntarily upload their files for other teachers to use. When a teacher submits a file, it is catalogued and placed into a database.

 


Subduction Boundary Lab
In this lab activity, you will plot and compare actual earthquake foci data from two areas where subduction is currently occurring. One of the areas includes the Tonga Islands in the southwest Pacific Ocean. The other area is along the coastline of Chile.

Tectonic Time Trials
Jeopardy style questions. Divide the class in two groups and have fun answering these questions.

Two Cell Convection and Rifting Model
Here is a dynamic model that shows two convecting cells that are maintained by a continuous heat source and made visible by markers that remain discrete and will not disperse in the convecting medium.

Sea Floor Spreading
Along the entire length of Earth's mid ocean ridge, the sea floor is spreading. Although this process takes place constantly, it is difficult to observe directly. In the following activity, you will build a model to help understand this process.

Travel Time Curve
Students use their reference tables to answer questions regarding earthquake epicenters and time of origin.

Earth's Interior Powerpoint
This powerpoint will help teach the parts of the Earth's Interior Chart in the Reference Tables.

Plotting Epicenters
The data below shows the P- and S-wave arrival time difference determined from seismograms from three different cities, for three different earthquake events. Use your travel time curve to determine the distance to epicenter for each city/earthquake.

Pacific Rim Tour
I introduced my students to a set of pictures demonstrating volcanic and earthquake activity around the Pacific. Then I sent them on a flying tour of ~24 stops, starting somewhere above the southern tip of S. America, all the way north to the Aleutians.

Ramapo Fault
The Ramapo Fault forms the boundary between the Triassic Lowlands and the Hudson Highlands of SE NY and shows up clearly in the distance in the image.
