It depends on the size of the star forming. For a one solar-mass star it lasts about 1,000,000 years.
It is the stage at which the gravitational collapse of a swirling mass of dust and gases reaches a critical mass at which sustained thermonuclear process begins.
If you're talking about the basic water cycle, starting in the ocean, water evaporates into vapor (Evaporation) rising up until it reaches it's the dew point, then the water condenses and travel towards higher ground, sometimes it travels as far as sea level ground (Condensation), when it reaches that heavy point where the clouds is too heavy to carry the water it drops taking about 10-15 minutes from the clouds to reaches the surface of the Earth if clouds are in the strato zone (Precipitation).
The Summer Solstice is the day on which the Sun reaches its maximum elevation north of the equator. This occurs on June 21 or June 22 in the northern hemisphere, depending on the cycle of leap years. It is also the longest day of the year.
a super nova is not something that anything goes into. A SUPER NOVA is a part of a stars life cycle when it explodes. THEN all the dust and chips of the star reunite in a super nova remnent forming a COMPLETELY NEW STAR.

Plants begin as seeds. The seed sprouts, forming a seedling. The seedling grows, becoming a plant. In some cases, after a plant reaches adulthood, flowers bloom.

Yes snow is a part of water cycle. It reaches earth after precipitation
Water cycle produces rain. The rain reaches earth's surface.
Percipitation- raining, collection-landing, evaporation-evaporating and Condensation-forming in the clouds
Cellular respiration or the Krebs cycle.
