oblique orbits answered by daylon oliver
they are using the maps at that time
Satellites collect lots of information that we use everyday. Some examples are the weather, pictures of other planets or star's, the geographical location of objects (such as a car used for GPS), and the effect of global warming and pollution.
Only if you are using a pinhole camera.If you reduce the aperture you will increase the depth of focus, but you can't decrease the aperture to a pinhole on most cameras.
This allows them to see the entire surface of the Earth. The Earth is rotating East to West. (Or West to East if you were the satellite.) If you placed a satellite into an East-West orbit, it would not see the polar regions. If it were high enough (geo-stationary), it would only see one spot on the Earth. By using North-South (polar) orbits, the satellites will, after several orbits, be able to see the entire surface of the Earth.
Using an imaging radar. Also known as Synthetic Aperture Radar (SAR).
light emitted by the satellites
Data is sent to earth from satellites using TIROS. This is data given from the ground.
Some natural satellites were created there, but artificial satellites are placed there using rockets.
investigation
by using telescopes and satellites.

thorough triangulation
Cyclones can easily be tracked using satellites.
No, satellites are not used in tracking tsunamis. Tsunamis are instead tracked using buoys spread throughout the ocean.
Once in space, most satellites obtain their power from the Sun using solar panels. Satellites travelling deep into space often carry additional nuclear power supplies.
We do not HAVE to use satellites. You can look up and see the sun or stars - depending on the time of day - using only your eyes.
GPS needs signals from at least 4 satellites to accurately calculate a 3D position on Earth. By receiving signals from multiple satellites, the GPS device can triangulate its position using the known positions of the satellites. This allows for highly accurate location determination.
