The Earth poles act as a regulating thermostat over the Earth. Forces are all the time sorting, for instance tree and earthlings processing and filtering air and materials. The oceans maintain a pH level, salty and the beach sand is moved as am machine to filter the oceans.

In the motions of the state of the beach can the situation be determined.

• the washing machine - the beach has severe impurities both biological and non-biological that violent mixing and motions are required.

Two beach engineering are observed, both designed as water purifiers.

Beaches with

• Maximal glide: the water forms silky thin layers and glides over flat sand a long way. This is all about maximum surface area. This type of beach is formed using sandbars that break the wave early, leaving the force in the water to glide a long way. Some beaches are shallow and when the glide occurs it goes wide and long.
• Incline grind: the shore is of an ever-increasing incline where the water also gliding, must glide uphill to an ever-increasing incline. This puts a lot of pressure on the water to filtrate. When the water recedes, much of the water falls into the sand via gravity rather than an unimpeded return.

The sand is the medium for filtration of water, and water itself is an air filter. The biome of the Earth, trees and humans, earthlings also process the air and other materials. How did the system concentrate the sand by the beach? The electromagnetic prime mover is by cause of a system design.

Beach today was big waves, pushed all the rubbish away from the shore and left clean sand behind. Interesting, ocean maintains, reconditions its purification medium. Every now and then the sand is flushed of its impurities and reused again.

Beach today was big waves, pools formed on natural valleys in the sand, little animals that burrow themselves in the sand, turn the sand into a porous sponge making the sand more absorbent allowing for more efficient purification of water.

The nearest identical example is the gut biome. It is very likely the trees and humans, earthlings are the biome of the Earth, and we regulate, filter and sort the atmosphere as the trees do. We are then a product of the Earth, formed by the Earth.
