What causes volcanic activity in the middle of a lithosphere plate?
the plates crash over each other.
When does an earthquake occur along a fault?
plates of the earth crash into each other along faults causing an earthquake
How does satellites avoid collision?
The vast majority of satellites are in geo-stationary orbits. This means, they travel around the Earth at the same speed that the Earth rotates - making them appear in the same place. One example is the GPS satellite network. Other satellites that actually orbit around the Earth, are at a different altitude - so they would (thoretically) never collide with a stationary one. Those that are orbiting, are placed in such a way, that they also avoid each other.
What are two names of different satellites?
Anything in orbit could be considered a satellite. There is one natural satellite - the moon. There are hundreds of navigation, communications, weather, science/experimental and military/intelligence satellites in orbit. There are thousands of bits of "space junk" orbiting the earth at present.
Where does earthquake occurs?
They happen along the fault lines that separate or crash into each other. The planet is made of Tectonic plates that are constantly moving, and that's why earthquakes happen
What is it called when two satellites almost crash into each other?
Gravity
Why does the moon not crash on earth but stay in space and not float away or into earth?
The moon and other planets and their satellites are held in space by the force of gravity from other planets and satellites. If the moon tried to drift off into space, gravitational forces from the Earth will keep it from floating away. It doesn't crash into the Earth because planets and moons pull AGAINST each other and keep each other from drifting away.* * * * *Only partly true.The moon does not float away because of the action of earth's gravity - whether you view this as a force or a distirtion of space-time in the moon's path.The moon does not crash into the earth, not because of other planets or satellites, but because of the momentum of its orbit around the earth.
Where do artificial satellites come from?
Artificial satellites come from all over the world. Each country send their own satellites into space.
How is it that the satellites do not clash with each other?
There is actually a surprisingly small amount of satellites considering the amount of space they are spread over. They don't hit each other mainly because they are very small, but they also have small rockets on them so they can make small changes in their direction if it looks like they might hit something.
What is a small rocky particle that moves through space and most often is about the size of a grain of sand?
A small rocky object that orbits the Sun is an asteroid. The Asteroid Belt, a collection of many asteroids, is located between Mars and Jupiter.
How does the earth the stay in space?
Both the Sun and the Earth exert gravitational pull on each other; the resulting tension causes the Earth to remain in space rather than crash into the Sun.
How can two orbiting satellites be joined?
the same way rockets, space shuttles and space stations join up. travel in the same direction, same orbit, similar speed and slowly approach each other
Who was involved with the space race?
The United States and the USSR were involved in the space race. Each one was trying to be the first to explore space with artificial satellites and manned spacecraft.
What are the different space satellites in the outer space?
there are many satellites in space.there are natural satellites and manmade satellites.For example,Earth"s natural satellite is the Moon.there are more than 3000 satellites in space!Some examples of their users are:weather forecast,communication from one place to another quickly.etc
Do satellites repel each other?
No, in orbit a satellite will be attracted to another satellite.
Why don't satellites crash into earth?
Well, they do eventually, when they're done doing their jobs. If defunct satellites don't burn up on their way down, they usually land in the ocean or somewhere else away from civilization. As for why that doesn't happen immediately, it's science, baby. Satellites are launched into space by rockets, and even though the force of gravity pulls on them, the initial velocity from the rocket is enough to counteract gravity's pull. The closer the satellite is to Earth, the faster it needs to go to stay in orbit. Sometimes they need to change orbit to avoid bumping into another satellite or other space debris, but once they're out there, satellites can stay in orbit for hundreds of years.
Two satellites orbiting the Earth pass close by each other each day Which of these best explains why the gravitational force between the satellites would increase as the satellites moved toward each?
The gravitational force between objects increases as the distance between objects decreases.
