Systems in Earth Science

What systems can you find within the Earth sciences? How do they work? How do they interact with each other? Within its new online Earth sciences theme, SEED has collected articles, activities, animations, and simulations to highlight the many systems of Earth.

Take the Pulse of Your Classroom

The following activity can leverage SeisMac technology to help students understand how a seismometer records ground motions.

Temperature and Precipitation Connections

No matter where we are on Earth, we can observe changes in vegetation. Some changes are drastic, such as going from dormant to full growth during a temperate winter.

Vegetative growth is dependent on both surface temperature (which influences soil temperature) and precipitation (which influences soil moisture). Together these environmental variables help determine the beginning, duration, and end of the growing season; the latter marked by leaf senescence, when leaves of deciduous trees die and turn colors.

Test Basic Page

Since October 1998, the American Geosciences Institute has organized this national and international event to help the public gain a better understanding and appreciation for the Earth Sciences and to encourage stewardship of the Earth. This year's Earth Science Week will be held from October 9-16, 2016 and will celebrate the theme "Our Shared Geoheritage." Geoheritage is the collection of natural wonders, landforms, and resources that have formed over eons and come to this generation to manage, use, and conserve effectively.

Texas Rocks

Geologic maps can tell you a lot about the rocks beneath your feet. You can use the legend with the map to figure out what rock types are in various geographic areas. The legend can also tell you in what geologic period those rocks formed. Geologists use such maps to help identify where natural resources are and where natural hazards are likely to occur. They are also critically useful in other ways, such as in making wise land use decisions.

The EarthTrek Gravestone Project

The Gravestone Project, part of the global citizen science program called EarthTrek (www.goearthtrek.com), is seeking volunteers to visit cemeteries around the world and collect scientific data on how marble gravestones are weathering.

The Great Ocean Conveyor

Learn about ocean currents and systems in this activity from NOAA.

The Mountain Blows its Top

Students will observe fault movements on a model of the earth's surface.

The Slope of Land in Your Community

The slope of the land and the materials under ground must be considered when planning how to build on the land in a community to lessen landslide risk. Changing the slope of the land (or even the amount of vegetation on a slope) can have dangerous consequences. This activity will introduce you into thinking critically about the land in your area!

Third From the Sun

In 1972, NASA launched a special satellite called Landsat that contained a new camera designed to take pictures of the Earth. Why was this satellite so incredible? Well, it could take a series of pictures of almost the entire Earth over and over again, season after season, month after month, year after year. You will be seeing Landsat images in this activity and learn how to interpret them.
