Question

Compared to the size and density of Earth, the Moon has a A. smaller diameter and lower density B. smaller diameter and higher density C. larger diameter and lower density D. larger diameter and higher density

Answer 1

Answer:

(a) Moon has smaller diameter and lower density than earth

Explanation:

Moon has smaller diameter than earth earth has a diameter of 12742 km whereas moon has a diameter of 3474.21 km

So for density density is given by $density=\frac{mass}{volume}$

From the relation we can see that density is dependent on mass and volume directly proportional to mass and inversely proportional to diameter

But in case of earth and moon mass is more dominating than volume so density is less for moon than earth
