Percolation typically occurs in porous rocks, such as sandstone or limestone, that have permeable spaces for water to flow through. These types of rocks allow water to seep through easily, making percolation possible.
What processes must occur to produce an igneous rock
For a new moon to occur the moon must be between earth and the sun
Oxygen gas must be present for a combustion reaction to occur.
A precipitate, water, or a gas must be produced for a double displacement reaction to occur.
Before precipitation can fall to Earth's surface, water vapor in the atmosphere must condense and form clouds. Once the clouds reach a point where they can no longer hold the condensed water, precipitation such as rain, snow, sleet, or hail will fall to the surface.
Evaporation and condensation
False. Condensation can occur when air is cooled to its dew point, regardless of the presence of a solid surface. Condensation happens when the air becomes saturated with water vapor and moisture in the air begins to form liquid droplets. This can happen in the atmosphere or on any surface, not just solid surfaces.

Actually not all plankton does, there are many types of plankton. Phytoplankton are the type that must be near the surface to survive because they are similar to plants in that they must be in an environment in which photosynthesis can occur.
Mitosis must occur in budding.
The changes to the rock must occur in solid form.
mating must happen randomly
colour must occur in one of three ways: light must be refracted off a surface. light must pass through a fliter or prism or liquid. light must be projected. Of the correct wavelength to produce a colour. the light must then pass into the back of the eye and hit the rods and cones at the back of the eye. Then the brain must process the image through the optic nerve.
There are many things that must occur for you to see. You must have optic nerves that are in tact for example.
Firstly, are they allowed and secondly will your location pass a percolation test (a test of your soils ability to absorb liquid.)
