What is the minimum number of artificial satellites required for communication through the globe is?
3 GEO Satellites located at 120 degrees are required to cover whole of the earth.
What is the motion of an artificial satellite?
Artificial satellites orbit the Earth. Some are geostationary - means that their orbital period matches the revolutions of the Earth, keeping them in the same spot over the surface all the time. Other travels roughly pole-to-pole, allowing them to cover the whole Earth as the Earth rotates beneath them.
How much surface area of the earth is covered by greenhouse gases?
Greenhouse gases, particularly carbon dioxide, are part of the Earth's atmosphere; as such, they cover all of the Earth's surface. The whole world is covered by atmosphere.
What is a non Geo stationary satellite?
Non Geo stationary satellite is that satellite which has different angular velocity from earth and not placed on the height of 36000 Km from the earth. If you use Geo stationary satellite than only 3 satellites are enough to cover whole world. most of satellite are geostationary and they are(most of them) active satellites too.
Why do satellites have a period of rotation equal to the earths period of rotation?
Some satellites cover the whole earth each pass, because that is what they are used for. However, many also cover nly certan regions such as the poles or the equator or one continent or one country. Geostationary orbiters for example, stay above the same place forever (that is, until they are taken or sent down by something). Many orbit over the same places each time, covering the same regions each pass. This is true of all satellites, the difference is how large the regions are nd how many of them. Some satellites cover the whole earth each pass, because that is what they are used for.
Where did the waters of the earth came from?
A mist used to rise from the surface of the earth and water the whole surface of the earth. Hope this helped!! :)
How does a GPS (Global Positioning System) work?
A GPS works by satellites that are located in outer space. These satellites are connected with cameras that show the whole earth. You GPS and the satellites systems are working together to provide maps for you.
How does the density of the earth provide evidence that the interior of the earth is denser that the surface?
The density of the Earth as a whole has been calculated by observing the orbits of the moon and artificial satellites, trajectories of near earth asteroids, etc. We can measure the density of materials from which the surface is composed. The two are not the same. That tells us that the density of the interior is different from the density of surface materials. Since the overall density is greater than the density of the surface materials, the interior must be denser still in order to bring the overall density to what has been observed and calculated.
Does the atmosphere cover most of the Earth?
In my humble opinion, I think it covers the WHOLE earth
When earth was formed its whole surface was comprised of which rock?
quartz
What are the tides that happen across the whole earth's surface called?
Tides
DID AN Ice dome cover the whole earth?
no....it has never happend and it wont ever......
