It is so cold.
High pressure zone.
The unsaturated zone is also known as Zone of Aeration.
the movement of deep, cold, nutrient-rich water goes up to the surface. Up-welling can be rising of any liquid. water moving up from the benthic zone
Its when a Aquifer recharges bc the surface has to much water realeasing the discharge of water.

It is so cold.
Aphotic = no light so it is the zone below the depth of where light can penetrate. Depends on several things. The clarity of the water. less stuff in the water the farther light can go. There are no plants in the aphotic zone. Generally, there is less oxygen (and sometimes none) in the aphotic zone, but some animals can be found there. It depends on how deep this zone is and how well mixed the water column is.

The aphotic zone is formally defined as the depth beyond which less than 1% of sunlight penetrates.
At the surface of the water to about 100 meters under the water.. The zone that receives the most sunlight.
The aphotic zone is the depth of a lake or ocean where less than 1% of sunlight reaches. In the ocean it begins around 650-3,000 feet, but it depends on water conditions (how dark or murky the water is).
the temp. of the aphotic zone biome is freezing and gets colder in depth.
Aphotic zone is the area of a lake or an ocean which gets little or no sunshine throughout the year.
Photic = where there's light Aphotic = where there isn't light, deeper waters.
Euphotic & Aphotic zonesEuphotic zone : is the upper layer of water that receives light and thus photothensythesis is possibleAphotic zone : is the portion of ocean that is not exposed to sunlight , and extends from - 0,9 - 4.6 kmEuphotic & Aphotic zonesEuphotic zone : is the upper layer of water that receives light and thus photothensythesis is possibleAphotic zone : is the portion of ocean that is not exposed to sunlight , and extends from - 0,9 - 4.6 km
