What to Focus On
- Earth is called a 'watery planet' due to its abundant water.
- Five major oceans: Pacific, Atlantic, Indian, Antarctic, and Arctic.
- Pacific Ocean is the largest and deepest.
- Submarine relief features are shaped by tectonic and volcanic activity.
- Continental shelf: shallow, gently sloping, up to 200 m deep.
- Continental slope: steep slope connecting shelf to deep ocean floor.
- Mid-oceanic ridges are volcanic mountain ranges at plate boundaries.
- Seamounts are underwater volcanoes that do not reach the surface.
- Guyots are flat-topped seamounts eroded by waves.
Common Mistakes to Avoid
All oceans are equally deep, so the deepest point could be in any ocean.
Continental shelves are part of the ocean floor, not connected to continents.
Oceanic ridges are found at the edges of oceans, like mountain ranges on land.
