What Are Features?
Try quickly grabbing a mirror and looking at yourself. Then, have your brother, sister, or friend look at themselves in the mirror. How do you look alike, and how do you look different?
Each one of you has special features that makes you who you are and unique, even though you are both human beings. Features are distinct characteristics of an object, place, or person in your case. Now, what if I asked you to do the same thing with two bodies of water, such as a lake and a pond? You would have to know each one's features to be able to tell them apart.
Bodies of Water
Lakes and ponds are only two of our world's bodies of water. Bodies of water are the parts of our planet Earth that are covered in water. There are different types of bodies of water - oceans, rivers, bays, seas, canals, lakes, ponds, and so on. We're going to pay particular attention to how to determine the difference between two bodies of water: lakes and ponds.
Examples of Lakes
Lakes are bodies of water that are surrounded by land. They are formed by basins, or bowl-shaped depressions filled with water in our Earth's surface. Lakes come in many different sizes and shapes and can be found all throughout our world.
The largest lake is the Caspian Sea found in the continents of Europe and Asia. It's over 143,000 square miles, which is almost as big as the state of California. Imagine that for a minute - a lake as big as a state!
Lakes not only vary in size but in depth as well. Lake Baikal in Russia is over a mile deep. It's the deepest lake in the world - you would have to swim close to seventeen football fields down to get to the bottom of this lake.
How Ponds Are Different from Lakes
Like lakes, ponds are bodies of water that are surrounded by land. However, ponds are less deep and smaller in size than lakes. Ponds also stay relatively warm when it's hot outside, since sunlight can reach all the way down to the bottom of the shallow water. In lakes, the water tends to be warmer on the top and cooler at the bottom because the sunlight can't penetrate that far into the deeper water.
If you go to a pond, you'll be more likely to see plants in the water. That's because some plant roots can grow in the the shallow areas of a pond. If the entire pond is really shallow, plants can grow all across its surface. Because of their deeper waters, lakes usually have plants only on the surrounding land area. Smaller ponds also change more with the climate than lakes do. When it's really cold outside, a pond will freeze, but a much bigger lake is less likely freeze, even if its waters are still icy cold.
Antonelli Pond in California is famous because this man-made pond was formed over a century ago or 100 years. Yes, I did say man-made. Ponds and lakes can both be made by us humans. Even though the pond is man-made and it's only 3 feet deep, it attracts a lot of wildlife.
Our world has different bodies of water that have special features, like lakes and ponds. Lakes are made from basins, are surrounded by land, and are much larger than ponds. Ponds are less deep and smaller in size than lakes, have plant roots growing in their shallow parts, and tend to change temperatures with the climate.
