Which feature allows students to explore underwater in Google Earth?

The feature that allows students to explore underwater in Google Earth is Ocean Explorer. This tool provides users with a rich and immersive experience by enabling them to dive beneath the water's surface and discover oceanic environments, marine life, and geographical features. It facilitates an engaging way for students to learn about oceanography and marine ecosystems through interactive layers and detailed imagery.

By using Ocean Explorer, students can access various educational content, including information about coral reefs, shipwrecks, and underwater habitats. This enhances their understanding of aquatic environments and encourages curiosity about the marine world, fostering a deeper appreciation for ocean conservation and exploration.

The other options, while they may sound relevant, do not specifically represent a feature within Google Earth that enables such experiential learning. By focusing on the immersive capabilities of Ocean Explorer, it stands out as the primary tool for underwater exploration in this context.
