Atmosphere and Climate
Grade 5-6, Earth & Space, Atmosphere and Climate UnitThe book Atmosphere and Climate introduces many important concepts about the atmosphere, weather and the climate. The troposphere is where weather takes place, and the stratosphere acts as a filter against harmful solar radiation. The greenhouse effect keeps Earth's surface warm. Air and water movement produce weather. Climate describes weather over long periods of time. Earth has three main climate zones: tropical, temperate, and polar. Human activity has led to an increase of greenhouse gases in the atmosphere. During the same period, Earth's average temperature has increased. Global warming is causing significant environmental problems. To address climate change, people are taking action to ensure that we can keep calling our planet a good home.
