Which of these is an incorrect description of “Mare Imbrium” on the moon?

Answer: It contains a certain amount of sedimentary water.

Some extra relevant information:

“Mare Imbrium,” also known as the “Sea of Rains,” is one of the most prominent and largest impact basins on the moon’s surface. It is located on the near side of the moon and is a well-known feature among lunar observers. However, it is crucial to note that the term “Mare Imbrium” refers to a lava-filled plain rather than an actual sea or body of water.

Contrary to popular belief, “Mare Imbrium” does not contain any water or liquid substances. Instead, the term “mare,” derived from Latin, refers to the vast dark areas on the moon’s surface that were once thought to resemble seas. These “seas” are, in fact, basaltic lava plains created by volcanic activity billions of years ago.

“Mare Imbrium” stretches over an area of approximately 1,100 kilometers in diameter. It is characterized by its dark, smooth appearance, which is a result of the solidification of the once molten lava. The basin walls surrounding “Mare Imbrium” are higher compared to other lunar features, with the Montes Alpes mountain range located on its northeastern edge.

This lunar feature holds great significance in studying the moon’s geological history, as it provides insights into past volcanic activities and the formation of impact basins. Scientists believe that the formation of “Mare Imbrium” occurred around 3.9 billion years ago when a massive asteroid or comet collided with the moon’s surface, creating a vast impact crater. Subsequently, the basin filled with lava, forming what we now know as “Mare Imbrium.”

In summary, it is incorrect to describe “Mare Imbrium” as an actual sea or body of water on the moon. Rather, it is a volcanic lava plain, one of the most prominent features on the lunar surface. Its dark appearance and large size make it a noteworthy feature for lunar observers and scientists studying the moon’s geological history.
