Explanation:
1. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.
Boiling point: 99.98 °C (373.13 K)
Solid state: Ice

3. Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. ... But farther away, the solar winds had less impact on lighter elements, allowing them to coalesce into gas giants. In this way, asteroids, comets, planets and moons were created.
4. Pockets of soil have accumulated within the limestone bedrock as a consequence of rock dissolution and illuviation of finer materials from topsoil. These soil pockets are thought to be additional sources of water and nutrients for plants but their abundance and properties have been poorly studied.
