it also revolves
The National Oceanic and Atmospheric Administration, or NOAA, has Geostationary Operational Satellites 22,300 miles above the Earth's equator. Since the satellite is rotating as fast as the Earth, it can constantly monitor weather systems and capture pictures.
Since we live ON the Earth, all satellites WE have sent have been sent FROM the Earth, and circle around it.
They actually didn't. Flat Earth is a myth. The spherical Earth has been a scientifically established fact since long before Ptolemy.
Weather forecasting and telecommunication have improved
No, the first man-made satellite was launched in 1957 by the then Soviet Union: The Sputnik-1 satellite.Natural satellites of courses existed since the creation of our solar system. For example, our moon can also be called a satellite of earth, but you are probably asking about man-made satellites?
Tides are caused mainly by the gravitational pull of the moon on the water in oceans and big lakes. Since the earth is spherical, the moon is in different positions relative to different spots on the earth.
The idea that the Earth is round - spherical - has been around since antiquity. Mathematicians in Greece and Egypt even had pretty good estimates of the size of the Earth by about 300 BCE.
The moon was studied to see how old it was. Since there is no atmosphere, we can study the effects of comets and asteroids far better.
Since the planet Earth actually is approximately spherical in shape (technically it is an oblate spheroid, bulging at the equator - somewhat like myself) a globe is a good model of what the Earth actually looks like.
Density = mass / volume since earth is nearly spherical, Volume = (4/3)pi x r3 find volume, then divide this into the mass.
rain drop is spherical since the surface tension of sphere is less when compared to other shapes.
well if the path of light is undisturbed by an object since the earth is spherical in shape, the light will go around the earth again and again untill the ray of the rectillinear propogation is disturbed.
