Question

Movement of stars as seen from the North Pole:

a. Stars appear to move in circles around the celestial pole.
b. Stars move vertically up and down in the sky.
c. Stars move in straight lines from east to west.
d. Stars remain stationary due to the observer's position.

Answer 1

From the North Pole, stars move in circles around the celestial pole and do not rise and set, making them appear to rotate around a nearly stationary North Star or Polaris.

Step-by-step explanation:

When observing stars from the North Pole, their movement across the sky is very distinctive due to Earth's rotation. The correct behavior of stars as seen from the North Pole is:

• Stars appear to move in circles around the celestial pole.

As the Earth rotates, the north celestial pole seems fixed at one point in the sky directly overhead, or zenith, and all the stars circle around it without rising or setting. Polaris, commonly known as the pole star or North Star, lies close to the north celestial pole, making it nearly stationary in the sky as seen from the North Pole. Thus, option (a), 'Stars appear to move in circles around the celestial pole,' is the accurate choice.
