What is the approximately height of a geo-stationary satellite from the earth's surface?
Before you begin, you need to know that a geosynchronous orbit completes one orbit every day.
Step 1
F= N/T= 1/1 day= 1/86400 seconds
T= 1/F= 86400 seconds
Step 2
The formulas we will use are:
v= square root of (Gme/r)
v= 2(3.14...)r/T * This is derived from the formula v=d/t, since the satellite is circling a sphere (circumference/time it takes to complete one orbit)
We already know the following information:
G= 6.67x10-11 N*m2/kg2
rE= 6.38x106 m
me= 5.98x1024 kg
v= square root of (Gme/r)
2(3.14...)r/T= square root of (Gme/r)
(2(3.14...)r/T)2= Gme/r
4(3.14...)2r2/T2= Gme/r
* cross out an r from each side and rearrange the formula:
r3= GmeT2/4(3.14...)2
r= cubed root of (GmeT2/4(3.14...)2)
r= cubed root of (6.67x10-11*5.98x1024*864002)/4(3.14)2
r= 4.22x107 m
Step 3
r= rE+ height above earth's surface
4.22x107= 6.38x106+ height above earth's surface
Therefore, the altitude of the satellite's orbit above the earth's surface is 3.59x107 m

In what type of orbit does a satellite follow the direction of the earths rotation seeming to hover over one spot on the equator?
Synchronous orbitThis is where an orbiting body (moon) has a period equal to the average rotational period of the body being orbited (planet), and in the same direction of rotation as that body.
What is a geostation satellite?
Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things. A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
Is the level of the ocean's surface used as a reference point when measuring height of depth of the earths surface?
Yes it is.
Can all 3 types of rock form on the earths surface?

How is a weather satellite in polar orbit able to view Earths surface?
From the question, I'm guessing that when the questioner reads the term "polar orbit", he's picturing the satellite doing a little tiny circle in the sky over the North Pole. This is not an accurate understanding of the term. Remember that the center of the orbit of an artificial satellite has to be at the center of the earth. A 'polar orbit' is an orbit that covers both poles. If you picture the globe of the earth, the satellite's orbit is a circle standing up, with the satellite traveling up and down, passing over both poles in each complete revolution of the earth. As the earth rotates, every point on earth passes under the orbit, and sooner or later, every point on earth will be visible from the satellite.
Where is a satellite when it stays at the same point above earths surface?
A satellite is considered to be in geostationary orbit when it stays in a fixed position above a specific point on Earth's surface. It orbits at the same rate as the Earth's rotation, which allows it to remain stationary relative to the ground below. Geostationary satellites are commonly used for communication and weather monitoring purposes.
An orbit in which a satellite travels at the same speed as the earths rotational speed is called?
That's a 'geosynchronous' orbit. If it also happens to be over the equator, so that the satellite appears to stay at the same point in the sky, then it's a 'geostationary' orbit.
What is a geostationary satellite?
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
Is hubble telescope geostatic?
The Hubble Space Telescope (or HST) is not in a geostationary orbit. The HST is located at an average altitude of 600 Km. Earths' geostationary orbit is at approximately 36 000 Km.
How are satellites stationed?
The time for one (stable) orbit is directly linked to the orbital radius. At one particular radius (geostationary), the resultant stable orbit velocity is exactly enough to match the rotation of the earth, keeping the satellite overhead at all times. This geostationary radius is approximately 42 000 km from earths centre and most geostationary satellites are roughly in the equatorial plane.
How far is the satellite from the earths surface at its apogee and at it perigee?
The distance of a satellite from the Earth's surface at its apogee and perigee varies depending on its specific orbit. Generally, at apogee, a satellite can be several thousand kilometers away, often reaching altitudes of up to 35,786 kilometers for geostationary satellites. At perigee, satellites are much closer, typically ranging from a few hundred kilometers to around 2,000 kilometers above the Earth's surface, depending on the orbit type. For example, low Earth orbit (LEO) satellites usually have perigee altitudes around 160 to 2,000 kilometers.
The oceans cover approximately how much of the earths surface?
97%
How many tenths of earths surface is underwater?
It is approximately seven.
What is the difference between geostationary orbit and sun synchronous orbit?
GEOSTATIONARY=GEO+STATIONARY MEANS EARTH+FIXED POINT thus geostationary orbit is orbit around the earth is in the same plane as that defined by the earths equator at an altitude of 22,236 miles (35,786 km eg say satellite such that it appears to be stationary to the orbit of the earth above the equator all day long. where as sun synchronous orbit occurs from north to south pole as the earth rotates
In what type of orbit does a satellite follow the direction of the earths rotation seeming to hover over one spot on the equator?
Synchronous orbitThis is where an orbiting body (moon) has a period equal to the average rotational period of the body being orbited (planet), and in the same direction of rotation as that body.

Why is it important that a satellite be above Earths atmosphere?
Please remember that close to Earth's surface, a satellite must move at a speed of about 7900 meters/second. If it is inside the Earth's atmosphere, the force of friction will make the satellite lose energy. As a result, it will soon crash to the Earth's surface.
