Question 42 If Santa flew from the North Pole due south along the \( 100^{\circ} \) meridian and did not correct his course, he would land on the \( 100^{\circ} \) meridian. south of the \( 100^{\circ} \) meridian. west of the \( 100^{\circ} \) meridian. east of the \( 100^{\circ} \) meridian.

To solve this problem, we need to understand the implications of flying due south along the \( 100^{\circ} \) meridian. 1. **Understanding the Meridians**: - Meridians are lines of longitude that run from the North Pole to the South Pole. The \( 100^{\circ} \) meridian is a specific line of longitude located 100 degrees east of the Prime Meridian. 2. **Flying Due South**: - If Santa flies due south along the \( 100^{\circ} \) meridian, he will remain on that meridian as he travels. This means he will not drift east or west; he will continue to be at \( 100^{\circ} \) longitude. 3. **Conclusion**: - Since he is flying directly south along the \( 100^{\circ} \) meridian, he will land on the \( 100^{\circ} \) meridian itself. Thus, the correct answer is that Santa would land on the \( 100^{\circ} \) meridian.
