[Free Registration/Login may be required to access all resource tools.] The atmosphere provides many important functions for Earth.

A discussion of the interactions between the four spheres of Earth and how they affect weather and climate. The slideshow is divided into two parts. The first deals with interactions between the atmosphere and the hydrosphere and the...

The Earth is surrounded by a thin envelope of gases called the atmosphere. More than 500 active volcanoes erupt around the world affecting the Earth's atmosphere and global climate.

Use this interactive infographic to learn about the function of greenhouse gases, and how they affect heat in the atmosphere.

Students study past climate change, explore the effect of greenhouse gases on Earth's atmosphere today, and consider human impact on global warming.

How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today.

The atmosphere has not always been the same. It has been much the same, but nevertheless now contains more nitrogen and oxygen, and less carbon dioxide, than it did when the earth first formed. Recently, the addition of greenhouse gases...

In this activity, students will observe the effect of the gases resulting from a burned fossil fuel on the heat absorption of air and determine the ability of phytoplankton to remove greenhouse gases from the atmosphere. This activity is...

In this activity, students plot data on the concentrations of various greenhouse gases in Earth's atmosphere and look for trends. They will learn that greenhouse gases allow the Sun's light to pass through them to the surface of Earth,...

One lesson in a larger module covering different aspects of the major greenhouse gases including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases.

This lab uses a robust model of the carbon cycle to give students an intuitive sense for how carbon circulates through the atmosphere, biosphere, oceans, and crust. It allows them to experiment with how human input to the cycle might...

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 2 of 3 in the series titled "The Biosphere."

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 3 of 3 in the series titled "The Biosphere."

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 1 of 3 in the series titled "The Biosphere."

There is evidence that the Earth's early atmosphere contained less oxygen but more carbon dioxide and water vapor than it does today. Increased emissions of greenhouse gases have led to climate change. Link to a test is included.

Learn about the properties of the thin layer of gas that surrounds the Earth. Understand the mixture of gases that make up the atmosphere as well as the different layers. Also explained are issues that affect the atmosphere like the...

Using this map from NASA you can calculate the concentrations of carbon dioxide in the atmosphere. Solve the four problems and you will see how concentrations are spread across the globe and where there are regional differences.

Are you studying or teaching Aerodynamics? This page acts as an index to all the terminology related to this topic. Clicking on any title will open a page with a colored slide and a scientific explanation of the contents. Animated,...

Breathing Earth layers data about rates of carbon dioxide emission along with birth and death rates onto a map of the world in a real-time simulation of one of the principal greenhouse gases in the Earth's atmosphere, CO2.

Includes exhaustive information and a wealth of activities pertaining to aerodynamics and the physics of flight.

This ClimateGateway.com site provides information on what climate change is as well as the factors that affect global climate.

Students are introduced to the concept of air quality by investigating the composition, properties, atmospheric layers and everyday importance of air. They explore the sources and effects of visible and invisible air pollution. By...
