1.The weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting, covering the entire Earth asynchronously, or geostationary, hovering over the same spot on the equator. ... The Antarctic ozone hole is mapped from weather satellite data.

2.Craters are formed by the outward explosion of rocks and other materials from a volcano. Calderas are formed by the inward collapse of a volcano's magma chamber. Craters are usually much smaller features than calderas, and calderas are sometimes considered giant craters.
