Where do you see particularly high or low areas in the oceans?

There are several high and low areas in the oceans, commonly referred to as high and low spots or features. Here are a few examples:

1. High areas:
- Mid-Atlantic Ridge: This underwater mountain range runs through the Atlantic Ocean and is one of the longest mountain chains on Earth. It represents a high area where tectonic plates diverge.
- Marianas Trench: Located in the western Pacific Ocean, it is the deepest part of any ocean, reaching a depth of about 36,070 feet (10,994 meters) below sea level.

2. Low areas:
- Challenger Deep: This is the deepest point in the Marianas Trench, reaching a depth of approximately 36,070 feet (10,994 meters) below sea level.
- Sunda Trench: Another relatively deep trench located in the Indian Ocean, reaching depths of about 24,600 feet (7,500 meters) below sea level.
- Hudson Bay: Along the eastern coast of Canada, Hudson Bay is a relatively shallow area with an average depth of around 330 feet (100 meters).

It's important to note that the ocean floor is not uniform and has various ranges of depths across different regions.
