How Do Interactions Change Weather?

Earth is a closed system much like a sealed terrarium in which sunlight is the only outside source of change. The atmosphere is affected by the biosphere, the hydrosphere and the lithosphere. All of these spheres are contained within the closed system of Earth. The sun's energy provides an outside source of energy. Space debris such as meteorites, space dust, usually only produce minor changes in Earth's systems.

Try It:

Research ways that the biosphere, hydrosphere, and lithospheres affect weather. Topics that you might investigate include:

• Volcanic ash
• Greenhouse gases
• Ocean currents such as the Gulf Stream or El Nino
• Moutain range affects on climate
• Photosynthesis of plants or algea
• Changes in vegetation (e.g. burning areas, or cutting trees)

Presentation:

1. Use your research to prepare a presentation. Your presentation may take the form of a video, multimedia, or a poster.
2. Describe the topic you researched.
3. Provide the evidence you uncovered showing a link between the topic and Earth's weather.
