I think what your referring to is craters.
astronauts thought the moon was flat ,so they called some areas,seas.
The gravitational pull of the moon pulls the ocean up on the shore this is called high tide and when the moon releases the gravitational pull it is called the low tide
Low altitude areas on the moon are called maria, which are large dark plains formed by ancient volcanic activity. The maria are located on the side of the moon that faces Earth.
They are called high tides and low tides!
The low areas of the moon are called "maria," which are large, dark basaltic plains created by ancient volcanic activity. These areas are lower in elevation compared to the moon's rugged and heavily cratered highlands.

hollowed out places on the moons surface are called
When the Sun and Moon are aligned, you get what is called spring tides, with higher high tides and lower low tides.
Spring tides.
Yes, the Moon did have a very thin atmosphere called an exosphere. This exosphere is made up of very low-density gases, such as sodium and helium, that are constantly escaping into space due to the Moon's low gravity. The Moon's atmosphere is much less dense compared to Earth's atmosphere.
The dry flat regions of lava on the moon are called maria. These are large dark plains formed by ancient volcanic eruptions filling in low-lying areas on the moon's surface.
