* Statement 1 is incorrect: This is typically done using X-ray scanners or advanced imaging technologies like millimeter wave scanners, not traditional radar. * Statement 2 is correct: Radars, specifically weather radars, are commonly used to monitor precipitation. They can detect rain, snow, and other weather conditions by bouncing radio waves off precipitation particles. * Statement 3 is correct: Radars can be used to track the migration of birds and other animals.
