Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers. Seafloor spreading over the past 100 to 200 million years has caused the Atlantic Ocean to grow from a tiny inlet of water between the continents of Europe

The volcanic country of Iceland, which straddles the Mid-Atlantic Ridge, offers scientists a natural laboratory for studying on land the processes also occurring along the submerged parts of a spreading ridge. Iceland is splitting along the spreading center between the North American and Eurasian Plates, as North America moves westward relative to Eurasia. write paragraph here

Plate Tectonic Features Mini-report

You will select a feature of Earth’s surface at random. Research information about your feature (recording citation information) so you can write at least one paragraph about each of the topics below.

This is an example of a feature that occurs at a(n)

1. How did plate tectonics cause your feature to form? In two or three paragraphs, describe the plate boundary activity that causes your feature, the geologic timescale over which that activity occurs, what was there before your feature formed, and any other information that relates to the Earth processes that produced your feature. Information from different sources must be in different paragraphs
