Quiz on Ocean 🌊

The ocean is the largest and most important body of water on Earth, covering about 71% of the planet’s surface. It is divided into five major oceans — the Pacific, Atlantic, Indian, Southern, and Arctic. Oceans play a crucial role in maintaining the Earth's climate by regulating temperature, absorbing carbon dioxide, and producing much of the planet’s oxygen through marine plants like phytoplankton.

Oceans are also home to an incredible variety of life forms, from tiny plankton to giant whales. Beneath the surface lie vast mountain ranges, deep trenches, and mysterious ecosystems that remain largely unexplored. Besides being a source of food and minerals, the ocean supports global trade, transport, and recreation, making it one of Earth’s most vital natural systems.
