Technologies used to explore deserts include robotic rovers, satellites, online mapping software and image-processing programs. NASA scientists use robotic rovers to explore deserts to prepare for the desert-like terrain located on Mars and the moon.Know More
Rovers are used to explore extreme environments, such as deserts, that are not very hospitable to life. Sensors built into the rovers gather information about the environment and send it back to the scientists.
Satellites can also be used to explore deserts. For instance, satellites record images of Earth and relay the information to online mapping services. This information allows scientists to observe the topography and terrain from above. Then different imaging-processing programs are applied to the images provided by the satellites to enhance them.
A scientist explored and discovered a small crater in the Bayuda Desert in Sudan by using Google Maps, AstroFrac Tool and GIMP; AstroFrac and GIMP are image-processing software tools available for free online. The discovery of the crater in Sudan is doubly impressive, as small craters are difficult to find because they disappear quickly due to weather and water erosion. Free software tools such as these give those who aren't scientists the chance to explore deserts as long as they have Internet access and a computer.Learn more about Earth Science
Basalt is most commonly used during construction projects. It can be used as aggregate in asphalt and concrete pavements. It is also used as a road base, railroad ballast and cobblestone pavement. Basalt may be cut into thin slabs and used as monuments, building veneers or floor tiles.Full Answer >
Geothermal energy is used to supply heat for industrial purposes. It may also be used to promote agricultural and aquaculture production in cold climates by heating soils, aquaculture ponds and greenhouses. In addition, high-temperature geothermal energy is used to generate electricity.Full Answer >
Lead is used in a variety of consumer and manufacturing products, including ammunition, batteries, plastics, tank liners, pesticides and some metal alloys. The metal has been used since ancient times.Full Answer >
Deserts are important because they provide corridors for migration for a number of species and yield a number of water-soluble nutrients not available in comparable quantities anywhere else on the planet. The spread of these nutrients benefits species all over the planet.Full Answer >
