They are home to a wide range of amazing creatures, including fish, whales, and dolphins. ### Oceans of the world There are five major oceans: - **Arctic Ocean** - **Atlantic Ocean** - **Indian Ocean** - **Pacific Ocean** - **Southern Ocean** ## Characteristics of the Oceans - Oceans contain saltwater. - Ocean temperatures vary based on location and depth. - Oceans near the poles are colder. - Oceans near the equator are cold at the bottom and warm at the surface. ## Seas A sea is a body of water that is smaller in size and depth than an ocean. Some seas are located at the edges of oceans and are partially surrounded by land. ## Characteristics of the Seas - The waters in seas are salty. - Seas are smaller in size than oceans. - Because seas are shallower than oceans, their waters receive more light. Therefore, seas have a diverse range of marine species. ## Human Activities in the Oceans, Seas, and Coasts Oceans contribute over $1.5 trillion to the global economy annually. They are crucial for trade, tourism, and energy. ## Social Dimensions of Oceans Oceans play a vital role in coastal communities because they depend on marine resources to balance economic growth, social equity, and justice. ## Human Activities - **Fishing** - **Mining** - **Tourism** - **Commerce** ## Why are Oceans and Seas Important? - Oceans help regulate our climate. - They play a crucial role in keeping our planet's temperature at the ideal level. - Oceans absorb heat from the sun and help create weather patterns. ## Land and Water Features All countries are different, and you can see many types of places in them such as mountains, rivers, beaches, even in the sea like the islands. These differences are due to the **relief** of the land. Relief refers to the shapes and forms of the Earth's surface. Examples of different forms of relief include: - **Rivers** - **Beaches** - **Islands** Relief can be continental, coastal, inland, or submarine. ## Landforms and Water Features - **Plateau** - **Mountain** - **Mountain Range** - **Valley** - **River** - **Lake** - **Plain** - **Hill** - **Isthmus** - **Peninsula** - **Harbor** - **Beach** - **Cape** - **Archipelago** - **Cliff** - **Island** - **Sea**
