The land isn't actually flat. With so many hills and mountains it would be hard to tell. We are also to small to notice the land is slightly curved

Answer:

See explanation

Explanation:

The land around us appears flat because the Earth is just so unimaginably large, and the curvature is extremely small from our point of view. In reality, the land is slightly bendy, which is why certain structures (like very long bridges) need to be constructed with the curvature in mind, with different ends at slightly different elevations. Hope this helps!

A gas has a volume of 5.0 L at a pressure of 50 KPa. What happens to the volume when the pressure is increased to 125?
Alexeev081 [22]
The volume becomes two. You have to use the equation P1 x V1 = P2 x V2 
P is pressure and V is volume.
P1 = 50     P2 = 125
V1 = 5       V2 = v (we don't know what it is)
Then set up the equation:
50 times 5 = 125 times v
250 = 125v
the divide both sides by 125 and isolate v
2 = v
Therefore the volume is decreased to 2.
Also, Boyle's Law explains this too: Volume and pressure are inversely related, This means that when one goes up the other goes down (ie when pressure increases volume decreases and vice versa). Becuase the pressure went up from 50 KPa tp 125 KPa the volume had to decrease.

How do oceanographers define salinity?
Studentka2010 [4]

The oceanographers define salinity by the number of grams of salt per kilogram of water.  

Salinity is illustrated as how much salt is present in the given amount of water. It is dependent upon how much salt is found in the ocean in the specific regions. If there is a sunny environment, it may evaporate an ample amount of water, and leave behind a lot of salt, thus, the water has more salinity.  

The salinity of the ocean is usually measured in Practical Salinity Unit (PSU), it is a unit based on the characteristics of seawater conductivity.
