The partial pressure of CO2 in air decreases with the increase in altitude. Therefore,
increase in molar concentration of CO2 is smaller at higher altitudes than at lower altitudes for
increases in molar fraction of CO2. This study aimed to predict the effect of global CO2 increase
on net photosynthetic rate of spring wheat (Triticum aestivum L.) at high altitudes. The net
photosynthetic rate of spring wheat grown in Lhasa (3688 m above sea level), China, was compared
with that of the same cultivar grown in Sapporo (15 m above sea level), Japan. At the current level
of CO2, it was signifi cantly lower in Lhasa than in Sapporo, and stomatal conductance, chlorophyll
content (SPAD value) and apparent quantum yield were similar in both locations. The interaction
of CO2 level and altitude was suggested; the amount of increase in net photosynthetic rate caused
by increase in CO2 was smaller at high altitudes than at low altitudes. Lower CO2 partial pressure at
higher altitude could explain the difference in net photosynthetic rate between altitudes, and the
interaction of CO2 level and altitude.

How is air in high mountains different from air at sea level?
Air in high mountains is thinner because there is less atmospheric pressure as you go higher in elevation compared to air at sea level. The lower pressure at high altitudes makes it harder to breathe and can lead to altitude sickness if not acclimated. Additionally, there may be lower humidity levels in high mountain air compared to air at sea level.
Why does the level of oxygen decreases on high mountain?
The level of oxygen decreases on high mountains because the air pressure decreases as altitude increases. This decrease in air pressure results in lower oxygen content for each breath taken at high elevations, making it harder for the body to get enough oxygen.
Why is it more likely to have smog in places surrounded by high mountains?
High mountains can trap pollutants in valleys, leading to poor air circulation and higher concentration of pollutants. This trapped air, combined with emissions from transportation and industry, can contribute to the formation of smog in areas surrounded by high mountains.
Is there high or low pressure on top of mountains?
There is lower air pressure on top of mountains compared to sea level, due to the decrease in atmospheric density as altitude increases.
What is a landforms that has high elevation and a mostly flat surface?
the rocky mountains have high relief and high elevation
What is higher a continent or the ocean floor?
Since everything is measured at sea level then a continent would be above sea level thus higher than the sea floor which would be below sea level, but there are mountains under the sea that are every bit as high as the highest mountains on any continent.
Which has higher elevations Alaska or Florida?
Alaska. It has many mountains and highlands, whereas much of Florida is not very high above sea level.
Are mountains higher than plateaus?
Yes, mountains are typically higher in elevation compared to plateaus. Plateaus are elevated flat areas of land that are higher than the surrounding terrain but generally not as high as mountains, which are characterized by steep slopes and peak formations.
Are the coastal mountains bigger than the Rockies?
The Rockie Mountains are 4401 meters high whereas the coastal mountains are 4019 meters high so the Rockies are 382 meters higher than the coastal mountains
How is air in high mountains different from air at sea level?
Air in high mountains is thinner because there is less atmospheric pressure as you go higher in elevation compared to air at sea level. The lower pressure at high altitudes makes it harder to breathe and can lead to altitude sickness if not acclimated. Additionally, there may be lower humidity levels in high mountain air compared to air at sea level.
What are some high level words that begin with the letter M?
mountains
How are mountains and basins different?
Mountains are points of high elevation, or above sea level while basins have low elevations and are commonly below sea level.
Why is the air density so low on high mountains?
Due to altitude the higher you go the less dense air becomes. Since mountains are up so high the air is less dense than it is at sea-level. Air's density is highest at low elevations but decreases as elevation increases.
How high is the blue mountains Jamaica?
Jamaica's Blue Mountains are 7,402 feet (2,256 meters) above sea level
The rate of photosynthesis is likely to be high when the amount of chlorophyll is?
high. Chlorophyll is the pigment responsible for capturing sunlight to drive photosynthesis in plants. Therefore, a higher amount of chloroph is typically associated with increased photosynthetic activity.
Can poliswine evolve if its at level 100?
sadly......no it's level will be to high to get it higher
