Comment on this resource
Until very recently, planetary scientists had thought that Mars is a cold, dry planet. Then in the summer of 2000, NASA released images from the Mars Global Surveyor showing evidence of very recent seepage of ground water from crater and valley slopes in the planet's southern hemisphere. It seems that substantial reservoirs of the water that once may have run so copiously on the surface may still ... Full description.

NASA and Russian scientists have been selected to take the search for life in the solar system to the frozen reaches of Earth. Life forms (from diatoms and bacteria to mammoths) preserved in the Siberian permafrost can yield evidence about how life has changed on the molecular level and provide a treasure trove of ancient enzymes, proteins, and biochemicals. The ecosystems of the ice and permafrost ... Full description.

This site provides a discussion of the downward movement, or infiltration, of water from the surface into soil or porous rock. Graphics illustrate the processes affecting infiltration, including precipitation, soil characteristics and saturation, land cover, slope, and evapotranspiration. Links to additional sources of information are also provided. Full description.

This site uses Virtual Reality field trips in the Alvin submarine to the East Pacific Rise to explore hydrothermal vents. The education activites focus on 4 activities: Exploration, Observing (actual video from the seafloor), Mapping, and Collecting a Water Sample. Teaching materials for each of the explorations have been provided, each with two levels of assessment (basic and advanced). Full description.

This project examines the entire water system of an ancient city, including supply, distribution, use, and drainage. Until now, individual water system elements have been studied as archaeological objects, but infrequently subjected to analysis by such disciplines as fluids engineering and urban history. This work is part of two larger long-term studies, the first concerning the relationship between ... Full description.

This site presents clues to suggest that liquid water once flowed on Mars - raising hopes that life could have arisen there - but the evidence remains inconclusive and sometimes contradictory. Full description.

In this activity, students construct a "comet" from ingredients similar to those found in actual comets. They will learn about the behavior of a real comet by observing their model as the dry ice sublimates, and understand the concept of scale as they compare the size of their model to the size of a real comet. A list of materials and instructions are provided. This activity can be performed as a ... Full description.

NOAA's Paleoclimatology Program is working with scientists from around the world to study past climate in hopes of achieving a better understanding of the Earth's present and future climate. This site was developed to help educate, inform and highlight the importance of paleoclimate research; as well as to show how paleoclimate research relates to global warming and other important issues of climate ...

This site contains information about snow, glaciers, permafrost, sea ice and cryospheric trends. The cryosphere is the portion of the Earth's surface where water is in a solid form, usually snow or ice. Seasonal snow cover, the largest component of the cryosphere, covers up to 33 percent of the Earth's total land surface. Glaciers and ice sheets cover about 10 percent of the Earth's land area. Nearly ... Full description.
