Question

10) How do birds fly?
​

Answer 1

Answer:

the birds fly from its wing by moving them up and down very fast

Answer 2

Answer:

''When a bird is flying, their wings are flat so that the air flows easily around it in the direction the animal flies (like your hand cutting through the water or air). ... As the air flows over the wing, the air flows faster over the top than the bottom because the wing is slightly curved on top.
