Which of the following statements is/are correct? 1. Angular velocity for all locations on the Earth's surface is the same while linear velocity varies. 2. Linear velocity is maximum at the equator and minimum at the poles.

Both statements are correct. Since the Earth rotates as a rigid body, every location on its surface completes one rotation in 24 hours, so the angular velocity (about 15°/hour) is the same everywhere. However, the linear (tangential) velocity depends on the distance from the rotation axis, i.e., the radius of the circle of latitude. This radius is largest at the equator (about 1670 km/h) and reduces to zero at the poles, so linear velocity is maximum at the equator and minimum (zero) at the poles.
