D. Answer the question. Why does the moon have less gravity than Earth?

The moon has less gravity than Earth primarily due to its smaller mass. Gravity is directly proportional to the mass of an object; Earth, being much larger, exerts a stronger gravitational pull. In fact, the moon's gravitational force is about one-sixth that of Earth's, which means if you weigh 180 pounds on Earth, you'd weigh just 30 pounds on the moon! This difference in gravity also means that the moon has a weaker atmosphere and can’t hold onto gases like Earth does. So, while Earth’s thicker atmosphere supports life, the moon is left barren, with just a thin layer of particles. Imagine hopping around on the moon—it's like bouncing on a trampoline!
