Cosmic rays bombard the upper atmosphere (see Carbon 14 wiki):
"Carbon-14 is produced in the upper layers of the troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms. When cosmic rays enter the atmosphere, they undergo various transformations, including the production of neutrons. The resulting neutrons (1n) participate in the following reaction: : 1n + 14N → 14C + 1H"

What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
What is the mass number of carbon14?
Carbon is a non metallic element. Mass number of it is 12.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
What procces allows the water to enter the atmosphere?
The process that allows water to enter the atmosphere is called evaporation. Evaporation occurs when the heat from the Sun causes liquid water to turn into water vapor and rise into the atmosphere.
