Answer 1

Polar orbit- the satellite obits north and South relative to the Earth.  In other words, it passes over the north and south poles.  On each pass it "sees" a different swath of the earth.  It is used to track animal migrations, forest fires, mapping areas, etc.

These orbits mainly take place at low altitudes of between 200 to 1000 km. Satellites in polar orbit look down on the Earth’s entire surface and can pass over the North and South Poles several times a day.

Geosynchronous orbit AKA Geostationary Orbit-in this type of orbit the satellite is orbiting the earth in the same direction of the rotation of the earth---and at the same speed.  This means that it stays over the same point of the earth at all times.  Geostationary satellites provide a "big picture" view, enabling coverage of weather events. This is especially useful for monitoring severe local storms and tropical cyclones.  It is also used for ccommunications.

There is also a Sun synchronous orbit.  These are polar orbits which are synchronous with the Sun. A satellite in a sun synchronous orbit would usually be at an altitude of between 600 to 800 km. Generally these orbits are used for Earth observation, solar study, weather forecasting and reconnaissance, as ground observation is improved if the surface is always illuminated by the Sun at the same angle when viewed from the satellite.

Hey, don't say that you are dumb.  After all, you were introduced to this topic just today.  One can't remember everything!
