Final answer:
Applying knowledge of cardinal directions helps in determining the path of stars and the Sun, with east being the general direction of their rise and west for their setting. Facing south allows for a broad view of the night sky's constellations, making it an optimal position for stargazing in the Northern Hemisphere.
Step-by-step explanation:
Applying your knowledge of cardinal directions when viewing the stars can greatly enhance your astronomical observations. For instance, if you wish to use the North Star (Polaris) to determine the northern direction, you would face north where this star remains nearly stationary in the sky, providing a constant northern marker. By knowing the cardinal directions, you can also predict the path of the stars and the Sun as they move across the sky. Stars, the Sun, and the Moon rise in the east and set in the west due to Earth's rotation towards the east. For optimal stargazing, facing south in the Northern Hemisphere generally provides a broad view of the night sky, including a variety of constellations that rise and set.
Understanding the movement and position of celestial objects relative to cardinal directions can greatly enhance your ability to navigate the night sky. Orient yourself towards the West to see the sunset, and face East to observe the sunrise and celestial movements. In the context of the student's question, options (b) Face East to observe the sunrise and celestial movements, and (c) Orient yourself towards the West to see the sunset, are actions applicable to cardinal directions and stargazing, showing the relation between Earth's rotation and the apparent movement of celestial bodies.
