Study Notes
The seven continents and five oceans are crucial in shaping Earth's environmental systems, influencing climate, biodiversity, and human settlements. Understanding these geographical features is essential for effective environmental management.
- Continent — a large, continuous landmass distinct from others Example: Africa is known for its diverse wildlife and ecosystems.
- Ocean — a vast body of saltwater that covers a significant portion of Earth's surface Example: The Pacific Ocean is the largest and deepest ocean.
- World Ocean — the interconnected system of Earth's oceanic waters Example: Ocean currents distribute heat and nutrients globally.
- Climate Regulation — the process by which oceans and continents influence global climate patterns Example: Oceans help regulate Earth's temperature by absorbing heat.
- Biodiversity — the variety of life found in a particular habitat or ecosystem Example: The Amazon rainforest in South America is a hotspot for biodiversity.
