Tornadoes, hurricanes, droughts, floods, typhoons, monsoons--all of these weather formations can have devastating results. This thorough treatment of weather and climate considers the causes of these extreme weather conditions and takes a look at cloud formations, the water cycle, the changing climate, and weather forecasting. Color photographs and drawings help explain the text. An index, a glossary, and a list of suggestions for further reading are included.
Wind blows through hair, flaps against clothes on a clothesline, and pushes sailboats along in the water. We can hear it, we can feel it, and we can see what wind can do. Find out where wind comes from and how it affects our weather. Color illustrations and instructions for making a weather vane accompany the easy-to-read text and simple color drawings.
Some clouds grow as big as mountains and hold enough water to fill several large swimming pools. Snowflakes, made up of tiny ice crystals, descend from clouds when the air is cold. In this book, you'll learn about storms, snowflakes, rainbows, hailstones, and fog. You'll also learn what causes such weather disasters as tornadoes and hurricanes. Weather forecasting is discussed in detail. Color and black-and-white photographs, an index, and a glossary are included, along with suggested activities.
atmosphere The mixture of gases that surrounds the Earth, also known as air. The atmosphere forms various layers at different heights above the ground. The air gets thinner as it gets father away from the Earth until at last the atmosphere disappears into space.
energy The ability to do work, such as the ability to move an object by pushing on it. Energy can exist in many forms, including motion, heat, and electricity. Energy cannot be created or destroyed, but it can be changed from one form to another.
gas One of the three basic forms of matter. The molecules of a gas are constantly moving about. For this reason, a gas has no set shape or volume and will spread out to fill any space that is available.
weather The state of the atmosphere at a particular time and place. Weather is described by changing conditions such as the temperature and humidity of the air, the speed and direction of the wind, and the presence of rain, snow, or other precipitation.
wind A flow of air, especially a natural flow that moves along the surface of the Earth. Winds are named according to the direction they come from. For example, a west wind is a wind that blows from west to east.
