What else can I help you with?
How are satellite pictures of hurricanes taken?
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.
Have any man-made satellites been sent to the planet earth?
Since we live ON the Earth, all satellites WE have sent have been sent FROM the Earth, and circle around it.
Why did the people think that the Earth was flat 2000 years ago?
They actually didn't. Flat Earth is a myth. The spherical Earth has been a scientifically established fact since long before Ptolemy.
What describes how life on Earth has changed since artificial satellites have been placed in orbit?
Weather forecasting and telecommunication have improved
Why do tides occur at different spots on earth?
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.
What can natural satellites tell about earth?
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.
What is the strength of a globe as a representation of the earth?
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.
How can you calculate the density and volume of earth give the formula?
Density = mass / volume since earth is nearly spherical, Volume = (4/3)pi x r3 find volume, then divide this into the mass.
What is the satellite around the earth?
The only sizable natural satellite in orbit around the Earth is the Moon. The first artificial satellite was "Sputnik" launched by the Soviet Union in 1957, since then the number of artificial satellites around the earth is numbered in the thousands.
Can satellites orbit east to west around the earth?
Yes. The reason they normally don't is a question of energy (or cost). Since the Earth turns west to east you would have to overcome that component and THEN get up to orbital speed.
Do satellites move in the same pattern as planets and stars?
Obviously. Since they move in an ellipse around the Earth (or other central body), they change direction all the time. The only way NOT to change direction would be to move in a straight line; satellites don't do that.
What is the only satellite around earth?
The only sizable natural satellite in orbit around the Earth is the Moon. The first artificial satellite was "Sputnik" launched by the Soviet Union in 1957, since then the number of artificial satellites around the earth is numbered in the thousands.
