How do satellites travel around the world?
Satellites are able to travel around the earth by virtue of a phenomenon called centripital force (centrifugal force is a misnomer to the opposite effect). Imagine, an object traveling in one direction will continue to travel in that direction at the same speed unless acted on by a force (Newton cleared this one up for us with some degree of confidence). So if a satellite is launched into space the earth's gravity is going to pull it back toward the earth, however since the satellite is already traveling at such great speeds in a path that has been determined so that the velocity of the satellite always manages to be perpendicular to the force of gravity on the satellite. In this way the satellite manages to travel in an ellipse around the earth without additional propulsion.
What orbit would allow a satellite to see all parts of the globe?
A geostationary orbit would allow a satellite to see all parts of the globe as it orbits the Earth at the same speed that the Earth rotates. This means the satellite remains fixed above the same point on the equator, providing continuous coverage of that area.
What would happen if the path of a satellite if its orbit was tilted more?
If the orbit of a satellite is tilted more, it would result in a change in the satellite's ground track and coverage area. This change in inclination would also affect the satellite's position relative to the Earth's equator, potentially altering its visibility and communication capabilities with specific regions.
Some satellites are put into an orbit around the earths poles what is this type of orbit called?
A satellite orbiting around the Earth's poles is in a polar orbit. This type of orbit allows the satellite to pass over different parts of the Earth as it rotates below. Polar orbits are often used for Earth observation and surveillance satellites.
What causes the different parts of the moon to appear lighted?
The different parts of the moon appear lighted because of sunlight reflecting off its surface. As the moon orbits Earth, the angle of sunlight hitting its surface changes, causing different parts to be lit or in shadow. This results in the different phases of the moon as seen from Earth.
Why must scientists carefully set the speed of a satellite orbiting earth?
If the final speed is not the exact speed required for a circular orbit, the satellite will travel in an ellipse around Earth; the time for one revolution, as well as the highest and lowest parts of the orbit, will be different from the expected values. This may, or may not, be relevant, depending on what the satellite is used for. For example, a satellite may be designed to pass over a certain part of Earth every 24 hours. If the orbit is wrong, the timing - as well as the part of Earth over which it moves - will be off.

Why you will not get the same reading of mass if you travel to different parts of the world using a spring scale?
The gravitational force varies by earth density and altitude.

What differences in the Moon's pull on different parts of earth cause?
When the moon pulls on different parts of the Earth it causes tides
Why does air pressure decrease as you travel farther away from the earth?
the earth is made up of diferent parts and some parts of the earth is less dense than the other
What are the different outer parts of earth?
The outer part of the earth is the crust
Why do constllations appear in different parts of the sky at different times?
Because the earth constantly revolves about the sun and rotates on its axis, so different parts of the universe are visible from any one location on earth at different times.
When the earth rotates it does what?
Shows different parts of the planet Earth to the Sun.That is why we have day an night.
Can seismic waves travel through some parts of the Earth's interior?
yes they bounce around and when it goes in to a different layer its course changes and that's how they know what the 3 layers are like
