Answer:
Refer to the explanation.
Step-by-step explanation:
The moon appears round because of its gravitational force and the process of accretion during its formation.
Here's a brief explanation:
When the moon formed about 4.5 billion years ago, it began as a result of a giant impact between a Mars-sized body called Theia and the early Earth. This impact caused molten material from both bodies to be ejected into space. Over time, this material came together due to gravitational attraction and formed the moon.
Gravity is a force that pulls matter towards its center, and when enough matter comes together under gravity, it forms a spherical shape. As the ejected material from the impact coalesced to form the moon, its own gravity pulled it into a round shape, which is the most stable configuration for a celestial body.
The force of gravity acts uniformly in all directions, causing the material to be pulled inward, resulting in a spherical shape. Any irregularities or variations in the moon's shape caused by subsequent impacts or volcanic activity have been smoothed out over time by the moon's own gravity, eventually giving it a nearly perfect spherical shape.
It's important to note that while the moon appears round from our perspective on Earth, it's not a perfect sphere. The moon is slightly flattened at the poles and bulges at the equator due to its rotation. However, these deviations from a perfect sphere are relatively minor compared to its overall roundness.
