geocentric
Having or relating to the Earth as the center.
🌱He claims that, if you aren't a scientist, your consciousness is mostly geocentric for your entire life. 🌳The idea that the Earth is the center of the universe and that the sun revolves around it is an ancient one, probably dating back to the earliest humans. Not until 1543 did the Polish astronomer Copernicus publish his calculations proving that the Earth actually revolves around the sun, thus replacing the geocentric model with a heliocentric model （from Helios, the Greek god of the sun）. But geocentrism remains central to various religious sects around the world, and still today one in five adult Americans believes the sun revolves around the Earth. geophysics The science that deals with the physical processes and phenomena occurring especially in the Earth and in its vicinity.
🌱Located in the heart of oil and gas country, the university offers a degree in geophysics and many of its graduates go straight to work for the oil and gas industry. 🌳Geophysics applies the principles of physics to the study of the Earth. It deals with such things as the movement of the Earth's crust and the temperatures of its interior. Another subject is the behavior of the still-mysterious geomagnetic field. Some geophysicists seek out deposits of ores or petroleum; others specialize in earthquakes; still others study the water beneath the Earth's surface, where it collects and how it flows. geostationary Being or having an orbit such that a satellite remains in a fixed position above the Earth, especially having such an orbit above the equator.
🌱It was the science-fiction writer Arthur C. Clarke who first conceived of a set of geostationary satellites as a means of worldwide communication. 🌳We don't give much thought to geostationary satellites, but many of us rely on them daily. Anyone who watches satellite TV or listens to satellite radio is dependent on them; the weather photos you see on TV are taken from geostationary satellites; and military information gathering via satellite goes on quietly day after day. （Though the satellites that provide GPS service for your car or cell phone actually aren't geostationary, since they orbit the Earth twice a day.） By 2009 there were about 300 geostationary satellites in operation, all of them moving at an altitude of about 22,000 miles. Since they hover above the same spot on Earth, your receiving dish or antenna doesn't have to turn in order to track them. geothermal Of, relating to, or using the natural heat produced inside the Earth.
🌱Geothermal power plants convert underground water or steam to electricity. 🌳Geothermal comes partly from the Greek thermos, "hot" （See THERM/THERMO.）Most geothermal electricity is provided by power plants situated in areas where there is significant activity of the Earth's great tectonic plates—often the same areas where volcanoes are found. But hot water from deep underground may be used by cities far from volcanoes to heat buildings or sidewalks. And a newer source of geothermal energy relies on a less dramatic kind of heat: Individual homeowners can now install heat pumps that take advantage of the 50°-60° temperature of the soil near the surface to provide heating in cold weather （and air-conditioning in the warm months. These very small-scale geothermal systems may eventually supply more useful energy than the large power plants.

GEO comes from the Greek word for "Earth." Geography is the science that deals with features of the Earth's surface. Geologists study rocks and soil to learn about the Earth's history and resources. Geometry was originally about measuring portions of the Earth's surface, probably originally in order to determine where the boundaries of Egyptians' farms lay after the annual flooding by the Nile River.🌸
