What happens to a planes wing when air moves taster over the top of?

it has no effect

it achieves lift

it begins to decrease it's altitude

It achieves lift.

Explanation:

It achieves lift because "airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air. "
