The Majestic Ocean: A World Beneath the Waves
The ocean, a vast and deep body of water, covers more than 70% of Earth's surface. It dives down to the deepest point, the Mariana Trench. This mysterious world beneath the waves is teeming with life, from swift sharks to playful dolphins and colorful coral reefs. Yet, the ocean is more than a home for diverse species. It helps regulate our planet's climate, with currents distributing heat around the globe. Furthermore, humans heavily rely on the ocean for food, transportation, recreation, and even medicines.
