Answer:
<u><em>Gravity </em></u>
Explanation:
Basically, the sun keeps all the planets in the orbital motion by gravitational alignment. Just as the earth and moon have a similar gravitational pull towards each other. Galileo gave the idea of Copernicus theory. The theory also follows the models of the geocentric model of Ptolemy. Stars are at a fixed position from the sun and far away from the sun. As compared to the earth which is nearby and rotates on its axis from right to left.
A fault is a place where the crust of the lithosphere has fractured. :)
Answer:
Seafloor spreading results from intense activity in the upper mantle which cracks the crust and pushes it away.
Explanation:
Seafloor spreading is a process that was first noticed by Alfred Wegener and was used by him in his theory of plate tectonics. There are three types of plate boundaries; convergent boundary, transform boundary, and divergent boundary. The last one is the one where seafloor spreading occurs.
The convection currents in the mantle are the process that breaks up the crust and move the tectonic plates, and when there is higher activity than usual at some place it results in break up the crust of an already existing tectonic plate. Basically, magma rises at a higher rate and pushes through the crust, in this case, the oceanic crust, and it manages to gradually break through it and come out on the seafloor. By doing so, the magma and the pressure from below are pushing the two now divided parts of the plate. As the space between the two different parts becomes larger and large the density of the crust becomes smaller and smaller so more and more magma rises through. The magma quickly solidifies on the ocean floor and piles up, thus creating an underwater mountain range known as a mid-ocean ridge.

Hope this helps!
Explanation:
You would use lantitude and longitude to help navigate if you ever lost a GPS or when marking things on a map. It can also be useful while sailing.
Both use it. Aviation uses it when they are up in the air and cannot see the ground below them. The air control tells them cordinaites they should fly to. Where-as, transportation also uses it when they need to find a specific thing, like trains finding a station.
GPS works through satiliete signals in space reflecting points on earth into your devices.
They are rather accurate depending on wether your device is working and if the satiliete is working. A form of GPS (Kind of) is sports. They use the same system to broad cast live.
