Almost everything on Earth becomes more dense as it becomes colder. This is also true with water until the point that it freezes, when it becomes less dense. This means that water as ice takes up more space than water as a liquid. Ice is about 9 percent less dense than liquid water. That’s why an iceberg floats and doesn’t sink.
Snow is water in its solid state. Each flake is made up of an ice crystal and no two snowflakes have the same shape. In the Eskimo languages, there are over 15 words just to describe snow.
The Pacific Ocean makes up 48 percent of the world’s oceans. It’s the largest and deepest ocean in the world and spreads nearly halfway around the world. It’s so large that it could hold all of the continents and almost all of the other three oceans.
The Atlantic Ocean is the second largest ocean and borders the eastern United States, which includes the east coast of Florida. The Atlantic Ocean makes up 28 percent of the world’s oceans.
Matter is anything you can see, feel, touch, taste, or hear. There are three states of matter: solids, liquids, and gases. All matter is made up of very small particles called atoms. In a gas, the atoms, are far apart and moving at a rapid rate of speed. In a liquid, the atoms are closer together and move at a slower speed. A solid has atoms that are tightly packed together with little movement. Can you see the cool breeze on your face? No, but you can feel it. Can you see the smell of pizza? No, because a smell and a breeze are both gaseous states of matter. So, this tells you matter can be something you can’t see.
The Amazon River is home to some incredible animals. For example, the giant otter that can be over 6 feet long and weigh more than 70 pounds can be found here. Another rare animal found only in the waters of the Amazon River is the boto, or Amazon River dolphin.
The Amazon River is the largest and second longest river in the world. It empties more than 500 cubic meters of water into the Atlantic Ocean every hour. Hmm, let’s see. That would be like pouring 250,000 two-liter bottles of water into the ocean every hour.
