Learn about the layers of Earth's atmosphere: troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Find lots of information about our planet Earth here. Covers basic facts, Earth's history, layers of the Earth, plate tectonics, composition of the atmosphere, Earth's magnetic field, and some facts about our moon.

This teacher website provides a comprehensive lesson unit on the structure of Earth's atmosphere and how it sustains and impacts life on Earth and its ecosystems. Includes labeled diagrams, student worksheets, a slideshow, flashcards,...

This two-part resource explores the vertical structure of Earth's atmosphere. Content details the atmospheric layers, and the relationship between pressure and height in the atmosphere.

Article explaining what ozone is, how it forms in the atmosphere, and the environmental problems it creates. (Published: August 22, 2008)

Describes each of the five layers of the atmosphere from the troposphere, which is closest to the Earth, up to the outermost one, the exosphere.

Create a model to help learn the layers and structures within the Earth. Identify characteristics of each layer of the Earth.

Explore the atmosphere by launching Virtual Weather Balloons. This "virtual laboratory" simulation lets you investigate the layers of Earth's atmosphere.

A detailed physical description of Earth. Content includes information on the Earth's layers and geology of the surface, along with links to additional information.

Find out about the interior structure of the Earth and the role of seismic waves as they move through Earth's layers. The research details both compositional layers as well as mechanical layers.

Visit an active volcano site to find out the connection between the movement of the Earth's plates and the processes deep within the Earth's interior. [58:23]

Excellent Eight Planets site that provides a vast amount of information about planet Earth. Very comprehensive and complete site.

This video segment adapted from NASA describes the basic characteristics of our star, the Sun. Includes background reading material and discussion questions. Video length: 1 min. 28 sec.

Students build a model to learn about the cycle of erosion and deposition by water and wind which deposits layer upon layer of rock, soil, and organic material to the surface.

Trace the advance of the environmental movement from 1948 through the 1980s. Read about the legislation promoting a healthy environment passed under both Democratic and Republican presidents.

Take a journey to the center of the Earth and learn about the structure, material properties, and conditions inside our planet.

In this activity, students use popcorn to simulate the process scientists use to date layers in an ice core.

Overview of the Mesosphere, a layer of the Earth's atmosphere.

Apple provides a description of the USAtlas Geology app, developed by the USGS. The app provides 46 layers of vector information available at The National Atlas of the United States Website.

This site gives background information to ocean water and its contents. It has a link to an detailed chart showing the minerals and their content amount in ocean water. It also has links to activities.

Though we live on the surface of the Earth, we actually live at the bottom of an ocean of air. Dynamic layers of air interact with the Earth's surface and the Sun's energy to produce the phenomenon of weather. The atmosphere is...

What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper?...

Detailed overview of the stratosphere, a layer of the Earth's atmosphere.

This instructional activity will allow the students to understand the cause and effects of plates interactions. The students will learn that plate boundaries function as a release for much of the Earth's potential energy. The students...
