Green turtles use the Earth's magnetic field to navigate. They seem to use the field to tell them their latitude how far north or south of the equator they are. Explain how Knowing the direction?

of the Earth's magnetic field can help green turtles navigate.

Green turtles have magnetite crystals in their brains that allow them to sense the Earth's magnetic field. By detecting the strength and direction of the magnetic field, they can determine their latitude and use this information to navigate accurately.

For example, if a green turtle is swimming south and senses that the magnetic field is getting stronger, it knows that it is getting closer to the equator. On the other hand, if it senses that the magnetic field is getting weaker, it knows that it is moving further away from the equator.

By using this information, green turtles can navigate long distances across the ocean to find their nesting beaches or feeding grounds. This ability to sense the Earth's magnetic field is crucial for their survival and reproductive success.

Green turtles do not use the Earth's magnetic field to navigate. They use a combination of magnetic field information, landmarks, and the sun's position to navigate.
