crash into them when their useful life is done.

Oceanology is the study of the oceans; geology is the study of the earth; and meterorology is the study of the planets, meteros and the stars; so you have sea, land and the stars--almost like the SEALS--exceptionally well trained military men who serve on the sea, land and air.

Geo satellites have a proscribed speed since they must orbit in the equatorial plane of the planet to be stationary in the sky relative to points on the earth.  \n\nPolar orbits can be at any altitude, so the speed will vary depending.

The oceans are in relative equilibrium.  They aren't getting saltier.  There are several salt "sinks" which take the accumulated salt and remove it from the ocean.\n\nThe following is an excerpt from this Web reference on the subject:\n\nb. Sinks (removal processes) of ocean salinity include salt spray which is blown over land; at oceanic ridges magnesium and sulfate ions are incorporated into mineral deposits; calcium, sulfate, and sodium are deposited as biogenous sediments in animal shells and fecal pellets; most importantly, almost all ions can be absorbed to the surface of sinking clay and biological particles.\nhttp://www-ocean.tamu.edu/~duce/chapter07.html\n\nDoing a Yahoo Search for:\nocean salinity salt removal\nhttp://search.yahoo.com/search?p=ocean+salinity+salt+removal&ei=UTF-8&fr=slv1-&x=wrt\n\nyou can find a number of related articles that talk about what happens to the salt.\nhttp://www.palomar.edu/oceanography/salty_ocean.htm\nhttp://www.geo.arizona.edu/geo2xx/geo212_2/Lectures/OC05.SaltGas.pdf#search='ocean%20salinity%20salt%20removal'\nhttp://www.oceansonline.com/salts.htm

Satellite communication is usefull for long range communications. High frequency comm signal is propagating in a straight line. However, the earth curvature make a straight line path difficult to achieve over a very long range (i.e from jakarta - paris). \n\nIn this situation we can use satellite to overcome the earth curvature. Satellite acts as a mirror high in the sky. It reflecting (and also amplify) a comm signal from a transmitter in Jakarta to a remote receiver in paris.\n\nRemote sensing is another application of satellite. Remote sensing systematically photograph earth from space.

sea level is easy to measure. If the water is suddenly a lot closer to the road next to the beach, you know the level has risen. If it is suddenly a half hour walk across the mudflats to get to the water it has dropped.\n\nWe also have these things now called satellites, maybe you've heard of them. They are good for measuring the position of things very accurately. If they say the ocean is now bigger and the land is now smaller, well I for one would believe it.

"Tides are the periodic rise and fall of the ocean waters. They are caused by the gravitational pulls of the Moon and (to a lesser extent) Sun, as well as the rotation of the Earth."\n\nCheckout these site for more info:

The waters of the oceans are pulled downwards by gravity; they flow around the planet in currents.  The continents shift and drift and the water flows into the spaces left.  The moon's gravity pulls the water and creates tides.  The waters of our little planet are in constant motion.

HI \n      \n              YOUR QUESTION IS PLACEMENT OF SATELLITE AROUND THE EARTH. BEFORE GOING IN DETAIL YOU NEED TO UNDERSTAND GRAVITY. GRAVITY IS THE MAGNETISM OF EARTH THAT TRY TO ATTRACT ANY OBJECT NEAR THE EARTH WEATHER IT IS ON THE EARTH OR IN THE SPACE.\n       BECAUSE OF GRAVITY ONLY MOON KEEPS CIRCULATING THE EARTH.\n       \n            IN NORMAL PHYSICS RULES SAYS ANY OBJECT IN SPACE HAS ATTRACTION TOWARDS EACH OTHER, AND IT IS INVERSELY PROPORTIONAL TO THE SQUARE OF DISTANCE BETWEEN THEM.AND EQUALLY  PROPORTIONAL TO THE MASS OF THEM     \n      \n             SO NOW WHEN ANY SATELLITE IS READY TO BE LAUNCHED THEN IT WILL BE CALCULATED ACCORDING TO THEIR MASS SO THEY GET PERFECT DISTANCE. SO WITH SPACE CRAFT NOT THIS SATELLITE WOULD BEEN TAKEN TO SUITABLE DISTANCE AND BY USE OF ROBOTIC HAND IT WILL BE LAUNCHED IN IN SPACE, ONCE IT GETS IN ORBIT OPEN UPS ITS WINGS WHICH TAKES SOLAR ENERGY FOR MAKE THEIR PARTS TO BE WORKED.\n         \n           NOW OTHER RULE OF PHYSICS WILL WORK HERE THAT UNLESS AND UNTIL ANY EXTERNAL FORCE INTERACT WITH ITS MOTION NONE OF THE BODY WILL CHANGE ITS DIRECTION. SO SATELLITE KEEPS ON CIRCULATING AROUND EARTH LIKE MOON AND WORKS ON SOLAR ENERGY.

The bootom of the ocean has, of coure, a density larger than the surface of the ocean. Despite this large density, the bottom of the ocean is not motionless. It circulates around the globe on what is called the Ocean Conveyor Belt driven by differences in density at the bottom of the ocean.

Although the terms "ocean" and "sea" are often used interchangeably, a sea is generally considered to be smaller than an ocean. One definition of "ocean" is: a great body of interconnecting salt water that covers 71 percent of the Earth's surface. There are four major oceans—Arctic, Atlantic, Indian, and Pacific. However, some sources do not include the Arctic Ocean, calling it a marginal sea. The term "sea" is often assigned to saltwater areas on the margins of oceans, such as the Mediterranean Sea situated beside the Atlantic Ocean.

The dish is there in order to direct waves containing the information from the satellites into the antenna in order to give it a bigger target to hit from space. A smaller copper one would be a smaller target and more expensive

United States Strategic Command tracks objects orbiting earth.  An AN/FPS-85 phased array radar, located at Eglin Air Force Base, is the primary sensor used to track these objects.  The radar is capable of tracking objects the size of a soccer ball at 20,000 miles.  The quote following is from USSTRATCOM's website (see first link).  The second link provides additional information on the Eglin RADAR. \n\nFWIW, the Eglin RADAR is now receiving a major hardware and software upgrade under the SENSOR contract.  ITT is the prime contractor and Northrop Grumman is the major sub.\n\n"USSTRATCOM tracks about 8,500 man-made space objects, baseball-size and larger, orbiting Earth. The space objects consist of active/inactive satellites, spent rocket bodies, or fragmentation. About 7 percent are operational satellites, 15 percent are rocket bodies, and about 78 percent are fragmentation and inactive satellites."

Yes, moons are satellites

the ocean is like the wind it has layers of different kinds of salinity of water and tempratures.it has currents going one way and the deeper you go they go an other way some are slow while others can move at highway speeds.it is what keeps the oceans stired up .hot water on the top while you have very cold dense water on the bottom,the heat of the earth is the engine of life
