Mare Frigoris

Mare Frigoris, which means "Sea of Cold" in Latin, is a large, dark plain on the Moon's surface. It is classified as a lunar mare, a vast area formed by ancient volcanic activity. Unlike Earth’s oceans, these "seas" are composed of solidified lava and are relatively smooth. Mare Frigoris is located in the northern hemisphere of the Moon and is notable for its chilly temperatures and unique geological features, including craters and hills. It is often studied by scientists to understand the Moon's history and volcanic activity.
