Answer:
Lunar Prospector was designed to collect data to compile the first complete compositional and gravity maps of the Moon during its planned one year mission in lunar polar orbit. ... In March 1998, NASA announced that data from Lunar Prospector suggested the presence of water ice at both the lunar poles.
Answer:
1. In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.
3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.
