Lift occurs because the air pressure on the top surface if an airfoil wing is?

Lift occurs in an aircraft wing because the wind speeds up as it goes over the top of it. The wind is traveling at relatively the same speed over the bottom. The faster air that travels over the top causes the wing to have lift because the air pressure is lower over the top therefore the wing 'rises' in a way. Hope this helps :)

What is the result of the weight of a column of air pushing on an area?
You might have expected the result to be pressure, but it's not. Pressure occurs due to the bombardment of air molecules on a surface. The weight of a column of air causes so little pressure that it can be considered negligible.
When is condensation more likely to occur?
Condensation usually occurs on a surface that is cooler than the adjacent gas. A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of its liquid or solid phase at the temperature of the surface where the condensation is to occur. The process causes the release of thermal energy. Condensation occurs on a glass of cold water on a warm, humid day when water vapour in the air condenses to form liquid water on the glass's colder surface. Condensation also accounts for the formation of dew, fog, rain, snow, and clouds.
What reflection occurs when light hits an irregular surface?
Each ray of light is reflected according to the rules for a regular surface. But, because the surface is irregular, the direction of the reflected ray will vary from one point to another. This is called scattering.
When the irregularities of one surface come into contact with those of another surface occurs?
Friction.
What occurs when light hits a polished surface?
It is reflected.
A reduction of vapor pressure occurs with the addition of a nonvolatile solute to a solvent because?
There are fewer solvent molecules at the surface that can evaporate.
Why is it that the larger the surface area the higher the evaporation?
That's because evaporation occurs at the surface.
What occurs because of unequal heating of the Earth's surface?

What occurs because of unequal heating of earths surface?
wind
What occurs because of unequal heating of Earth's surface?

Which of the following occurs because of unequal heating of the Earth's surface?
The answer is the Winds
What gases are found in the atmosphere what gases are found in the troposphere?
About 90% of the atmospheric mass is in the troposphere. You can tell because 90% of the pressure increase occurs in the troposphere. Pressure goes from zero in space to 100 mb at the tropopause to 1000 mb at the surface.
Which occurs because of unequal heating of the Earth's surface?
Air current, winds.
What layers of small sediments stick together because when pressure occurs?
When layers of small sediments stick together because of pressure, compaction occurs. :)
Breathing occurs because of air pressure differences between the lungs and the?
Atmosphere
How is blood pressure affected when you increase dilation?
Blood pressure drops as dilation increases. This occurs because of decrease resistance.
Evaperation occurs when the earth's surface is heated by the?
Evaporation occurs when the sun heats the surface of earth.
