Climate and Factors that Affect It
While weather is a kind of day-to-day thing, climate refers to typical weather patterns over a longer period of time. This concept will examine patterns in climate change and how global warming may be speeding it up.
Energy Transfer and the Water Cycle
We have been told not to waste water, but in reality all water gets recycled. Water evaporates from bodies of water, from land, and from organisms as they transpire, and becomes water vapor in the atmosphere. When the vapor condenses, it returns to earth in the form of precipitation. In this concept, you will learn about energy transfer and the water cycle.
If you’ve ever counted on a snow day that didn’t happen, you’ll know that the study of weather is not an exact science. Forecasts often flop because meteorologists must interpret so much different information about phenomena in the atmosphere. In this concept you will learn more about meteorology.
Hurricanes, blizzards, and tornadoes disrupt daily life, and sometimes take lives. In this concept, you will learn how accurate weather forecasting can help people prepare for these extremes.
An immense body of water covers nearly 75 percent of Earth. The global ocean, or what we call "the oceans," is a tremendous resource containing countless species of living things. In this concept, you'll learn about the layers of the ocean, how it is a resource, and how technological advances allow humans to study the ocean in depth.
