What is sea floor spreading?
The process by which new sea floor is formed as it moves away from spreading centers in mid-ocean ridges.
What are some of the major land forms that are created from plate movement?
Mountains, volcanoes, trenches, and the 7 continents were all formed from plate movement.How were the Mariana Islands formed?
The Marianas were formed by volcanoes. Nowadays they are most dormant, but occasionally one will erupt, spreading sulfur up into the atmosphere and over the other islands.
What evidence exists today that the plates are still moving and that the islands are ancient volcanoes?
As I mentioned earlier, there are still active volcanoes in Micronesia, and which the continous earthquakes, we know that the plates are still in motion.
What is an atoll?
A product of a reef; often islands or sand cays surrounding a central lagoon.
Why are atolls mainly found on the Pacific?
Atolls grow on coral reefs, which are found mainly in the Pacific Ocean because of the warm climate.
