Earth observation satellites are satellites specifically designed to observe Earth from orbit, similar to spy satellites but intended for non-military uses such as environmental monitoring, meteorology, map making etc.
orbit
If the satellite is in an orbit that takes it over the North and South Poles, it will eventually cover all parts of the Earth as the Earth spins beneath it. This kind of orbit is called a polar orbit.
Yes
The Sun,Earth's orbit, the oceans,greenhouse gases,and dust.
The worlds' first artificial satelite was put in orbit by Soviet Union in 1957, named Sputnik 1. Since then thousands of prolab satelites were put in orbit by several countries around the globe.
The Earth's tilt and orbit cause seasonal temperature changes.
Temperatures are cooler because the Earth is further from the sun when it elongates.temperture is colder because the earth is farther from the sun
The axis is actually an imaginary line that the Earth spins around. It represents the tilt of the Earth relative to its orbit.
Earth
This is not something obvious; for example, it doesn't have much influence on the temperatures. It has been determined with careful measurements.
Tidal forces between the Sun and the Earth cause friction in Earth's surface - sort of a rippling - that slows the orbit. It is easier to see these tidal forces acting on the water in our oceans than it is to see in our land, but they are there.
Earth of course.
