Part of Hall of Ocean Life.
The ocean floor has a variety of geologic structures that formed as a result of the plate tectonics specific to the ocean crust. However, these landforms often resemble geologic features found on land.
Give your class a tour of the diverse landscape of your own undersea realm!
What you need:
What you do:
Explain to students that the ocean may appear to be one big homogenous body of water from above the surface, but below the surface it has many different shapes and habitats-similar to the land above water.
If you have access to a topological map of the ocean floor, lead students in a discussion of different elevation heights. Explore the ocean floor's seamounts and trenches. Discuss their heights and depths in terms of elevations that are familiar to the students, such as the height of Mt. Everest and the Empire State Building or the depth of the Grand Canyon.
