WATER HABITATS We already know that a habitat is the place where plants and animals live. Now, let’s look at WATER habitats… actionURI(http://www.kidzworld.com/article/1375-hydro-energy):Water actionURI(http://www.kidzworld.com/article/1375-hydro-energy): covers nearly 75% of the Earth: which means there is a lot more water than land on Earth! Most water on Earth is saltwater but some is freshwater. Freshwater is water found in waters such as rivers, streams, wetlands and many lakes. Many fish, birds, insects, amphibians live in or near freshwater. Freshwater is the water that we can drink (unlike saltwater). Let’s check what we have learned so far: What portion of the Earth is covered by water? © Copyright NewPath Learning. All Rights Reserved.

Rivers and Streams Rivers and streams have moving water. Rivers are large and flow into the ocean. The mouth of a river is where a river meets the ocean. Ponds A pond is a shallow area where water collects and fills up a large hole in the ground. Plants grow around close the edge of ponds and sometimes right across ponds. The temperature of pond is pretty much the same at the top as it is near the bottom since ponds are so shallow. There are usually no waves in a pond. © Copyright NewPath Learning.

Lakes Lakes are large bodies of freshwater that have land all around it. A lake is bigger than a pond. Plants can only grow near lakes, not across them, since lakes are so deep. Some lakes are so big that there are waves. Let’s check what we have learned so far: What is the difference between a pond and a lake? Wetland A wetland is a habitat that is covered with water. © Copyright NewPath Learning. All Rights Reserved.

What about Saltwater? Saltwater has so much salt in it that you can taste the salt! There is more saltwater on Earth than freshwater. Oceans An ocean has saltwater in it. An ocean is big and deep. Many animals live in the ocean, like whales and dolphins. Ocean water that is close to the top of the ocean is WARMER than the water that is closer to the bottom of the ocean. As the water gets deeper in the ocean, it gets colder and colder. This is because sunlight only reaches the water near the top of the ocean.
