What is a moon bump?

A moon bump, also known as a lunar swelling or lunar dome, is a geological feature found on the surface of the Moon. These bumps are typically broad, low mounds that can range in size from a few hundred meters to several kilometers in diameter. They are often formed by volcanic activity, with magma rising to the surface and creating a dome-like structure.

Moon bumps are made up of solidified lava flows and are usually composed of basaltic rock. They are often found in volcanic regions of the Moon, such as the lunar maria, which are vast plains formed by ancient volcanic activity.

Moon bumps are important features for scientists studying the geology and history of the Moon. By studying the composition and structure of these formations, researchers can learn more about the Moon's volcanic history and the processes that shaped its surface.
