Answer: B. the amount of fresh water required to mix and dilute pollution in the water.
Explanation:
a grey water footprint is the volume of fresh water that has ben assimulated to pollutants baced on back ground concentration and compisision it also test ambiant water standards to see the quality of the water it has a certain standered that has to be exceded in order to pass as clean water the cleaner the better it is for the ecosystem the minerals and life need the freshest water to drink (no that just is for fresh water sorces) but it is also used for the acidity of the ocean it needs to stay a certain saltyness or the fish and aquatic life will have to relocate or they will just die.
Seems very basic, the ocean is above the plate, the plate material is heavier than water (it being rock). That's pretty much all of it. The plates grind a little and new land pushes up at plate boundaries but this does not seem to be related. The heavier material is below and the lighter above, those being rock and water respectively.
Wouldn't that be because of the Tectonic Plates
We learn about this in my class A.
The beginning of the Precambrian<span> period starts with the formation of Earth about 4.5 billion years ago and ends at the first sign of complex life about 540 million years ago. Though the </span>Precambrian<span> Period is often referred to as a period, it's actually the only supereon, which means that it spans multiple eons. The Precambrian is known as the geologic era. The Precambrian is the 1st era. hope that helped</span>
