Answer:
Dissolved Oxygen and Water. Although water molecules contain an oxygen atom, this oxygen is not what is needed by aquatic organisms living in natural waters. A small amount of oxygen, up to about ten molecules of oxygen per million of water, is actually dissolved in water. Oxygen enters a stream mainly from the atmosphere .
Explanation:
I want to investigate how temperature affect the concentration of oxygen in air as it will affect how much oxygen we inhale per breathe. Oxygen by percent composition in air is 20.95%. However, the oxygen concentration/density in air varies due to the expansion of gas particles and varies inversely wth temperature according to P/RT=n/V.
Answer:
superincumbent load in rock slab
Explanation:
- This pressure is defined as the geothermal pressure that the rocks excerpt from above the surface of the earth which is caused by the weighting of the overlying rock strata.
- This identification can be found in geology itself in terms of fluids and natural gases which led to the formation of coal deposits millions of years ago. With great pressure and thrust from the rocks
- This burning pressure that the rocks feel from above as in the case of earth core and mantle layers. A tectonic plate is subdued to greater depths here and this layer and hence more pressure from the remaining earth mass from above.

The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.
Subtropical, it's a zone located between tropic of cancer and temperate zone. it's also present on southern Hemisphere, in this case its between tropic of capricorn and 38th parallel.
