Eighth graders examine the forces that are constantly acting on the Earth. They describe the theory of tectonic plates and demonstrate the two kinds of earthquake waves. They also examine the role of volcanoes in the structure of the...

Students define constructive forces. They describe how landforms are created as a result of constructive forces. Students recognize active volcano areas in the United States. They demonstrate an understanding of Panagea.

In this sentence completion practice test worksheet, students choose the answer that best completes the sentences.  Students have 10 minutes to answer 12 questions  in this SAT practice worksheet.

In this earthquake and continental drift worksheet, learners answer five questions about continental drift, seismic waves and earthquake safety.

Students classify earth's layers and plates using Ocean Seismicity data. In this plate tectonics lesson, students outline where the plate boundaries are on the world map. They then compare these predicted boundaries with USGS map of the...

An excellent biography of Wegener that includes his breakthrough work and the storm of controversy it created. Finally, Alfred Wegener has gotten the praise and recognition he deserved.

This is a thorough overview of Wegener's granulomatosis, a form of arthritis, which also includes information on symptoms, treatment, prevention, and so on.

Find out about the life and work of Alfred Wegener, known for his achievements in meteorology and as a pioneer of polar research, and is most remembered as the originator of the theory of continental drift.

Did you know the continents on Earth are in constant motion? Our knowledge of this is thanks to both Alfred Wegener and Harry Hess. This article discusses the work of these two scientists.

Complete biographical information with links to his theories. Contains links to interactives on plate tectonics.

This site from the United States Geological Survey provides a description of the scientist and his accomplishments.

A course lecture on how the Earth's geological features have evolved through the movements of tectonic plates. Explains the different types of plate boundaries and how they manifest in geological formations. Also describes the structure...

Article describing the history of scientific theories about continental drift, and the major researchers involved in this work.

A unit on plate tectonics designed for middle school young scholars, this page must be read carefully to find the activities to be done in the class, but it provides a wealth of background for the teacher as well.

Introduces South African Alexander Toit as naming Gondwanaland and Laurasia.

Discover Alfred Wegner's ideas relating to continental drift and seafloor spreading which are both evidence to the concept of plate tectonics.

Instructional module focusing on the development of plate tectonic theory. Discussion includes the evidence of Pangaea, and the processes of seafloor topography and seafloor spreading. Site also includes an interactive practice quiz and...

This resource looks at how geologists are able to measure the movement of tectonic plates using satellite-based data and how they were able to surmise in the past that the plates were moving. It also discusses how to read GPS time-series...
