Statement 1 is not correct: The pressure gradient is strong when isobars are close together and weak when isobars are far apart. This is because the pressure difference is greater over a shorter distance when isobars are closer together.

Statement 2 is correct: The pressure gradient force is produced by differences in atmospheric pressure, which causes air to move from areas of high pressure to areas of low pressure.
