Which layer of the earth weighs the most?
The layer of the Earth that weighs the most is the mantle. The mantle is a thick layer of solid rock located between the Earth's crust and core. It makes up about 84% of the Earth's total volume and contains a large portion of the Earth's mass.
Which layer of the atmosphere is the highest?
Mesosphere
Is the trophospere the layer of the atmosphere where most nitrogen and oxygen found in?
Yes, the troposphere is the layer of the atmosphere closest to the Earth's surface, and it is where most of the Earth's nitrogen and oxygen are found. This is the layer where weather occurs and where most life on Earth exists.
What is the most expansive layer of the Earth?
The most expansive layer of the Earth is the mantle, which makes up about 84% of the Earth's volume. It is located between the Earth's crust and the core and consists of solid rock that can flow slowly over long periods of time.
What layer is closest to the Earth's surface?
The crust is the outermost layer of the Earth.
Which factor would most likely cause communications satellite orbiting earth to return to earth from its orbit?
The most likely factor that would cause a communications satellite orbiting Earth to return to Earth from its orbit would be atmospheric drag. As the satellite moves through the Earth's atmosphere, it experiences friction with air molecules which can slow it down and cause its orbit to decay, eventually leading to re-entry into Earth's 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.
What are the most common space crafts that orbit the earth?
Aspacecraft/Satellite
What layer of the atmosphere do GPS satellites orbit in?
SatellitesSatellites orbit in outer space, not in the earth. They are sent to outer space where the gravitational pull of the earth pulls them around, just as the earth is pulled around the sun in a similar manner. The layer is the exosphere. It greatly depends on what the satellite is for and who owns it how far up it orbits. Imaging satellites need to be close to the Earth, so they orbit about 130 miles up. Communications satellites are generally at 23,000 miles up. GPS satellites are up about 13,000 miles.
Do the satellites orbit earth in the exosphere?
Satellites orbit Earth in the thermosphere and exosphere, which are the upper layers of the Earth's atmosphere. The exosphere is the outermost layer of the atmosphere where most satellites, particularly those in geostationary orbit, are found.
Do all satellites orbit the same direction?
No, all satellites do not orbit Earth at the same altitude. An good overview of this can be found on http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx. This overview reviews Low Earth Orbit, Medium Earth Orbit and Geostationary Orbits.
What is the name of the satellite visible over Skegness UK at about 21.00 on 2 Sept 2010 travelling approx west to east?
Are you sure it was a satellite ? The International Space Station is also visible from earth. Most satellites are in a geo-stationary orbit - in that they orbit the earth at the same speed the earth spins on its axis.
What are the main differences between geostationary orbit and polar orbit?
A polar orbit is an Orbit in which a Satellite passes above or nearly above both of the Geographical poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun being orbited on each revolution. It therefore has an Inclination of (or very close to) 90 degrees to the Equator. Except in the special case of a polar Geosynchronous orbit, a satellite in a polar orbit will pass over the equator at a different Longitude on each of its orbits.A geostationary orbit (GEO) is a circular orbit directly above the Earth's Equator From the ground, a geostationary object appears motionless in the sky and is therefore the Orbit of most interest to operators of Communication Satellites. Their orbital periods (time taken to revolve around earth) is exactly the same as the planet's (such as Earth's) rotational period. The Geosynchronous orbit is approximately 36,000 km above Earth's surface.geostionary satellites are positioned at an exact height above the earth, at this height they orbit the earth at the same speed at which the earth rotates on its axis whereas polar satellites have a much lower orbit, orbiting the earth quite quickly, scanning different areas of the earth at fairly infrequent periods.
The point Earth is farthest away from the Moon in its orbit is called what?
The point in the orbit of the moon or of an artificial satellite that is most distant from the center of the earth is called the 'apogee'.
What is the satellite that always stays over one spot on Earth?
A "geo-synchronous" orbit is one in which a satellite orbits in exactly 23 hours 56 minutes, the same rate at which the Earth spins. So while the satellite is moving and the Earth is moving, they are moving together at the same angular speed. This only works for equatorial orbits.
What do you call the point in a satellite's orbit farthest from its planet?
In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point is its aphelion and apogee, respectively.
Could a planet be a satellite?
By definition a planet cannot be a satellite. A planet is a body that has cleared most of the debris in its orbit about a star. However, a satellite might have an atmosphere. Titan, the largest moon of Saturn, has an atmosphere more dense than that of earth.
