The darker, roughly flat, plains of the Moon are called 'seas.'
The broad flat lava plains on the moon are known as maria, which is Latin for seas. These plains were formed by extensive volcanic activity billions of years ago, and they appear dark due to their low reflectivity compared to the surrounding highlands. The most famous example of a lunar mare is the Sea of Tranquility, where the Apollo 11 mission landed in 1969.
They are called lunar maria, formed by ancient volcanic eruptions that flooded the surface with basaltic lava. These smooth, dark areas contrast with the rugged, bright highlands on the moon.
The broad flat land that stretches from the Rocky Mountains to the center of the US is called the Great Plains. It is known for its fertile soil and extensive agricultural activities, and it covers states such as Kansas, Nebraska, the Dakotas, and parts of Texas and Oklahoma.
The high flat plains where the Andes mountains are the widest are called the Altiplano.
This landscape feature is likely a plain, which is a large area of flat or gently undulating land with minimal elevation changes. Plains are typically found at low altitudes and can be characterized by their expansive and relatively level terrain.

Broad flat lava plains on the moon are called maria. They were formed by volcanic activity in the past, where lava flowed and filled in large basins on the surface of the moon. The most famous example of a lunar mare is the Sea of Tranquility, where the Apollo 11 mission landed.

Think of walking across a flat surface (plains), and then walking up a series of hills (mountains). It's easier to travel across plains because they are flat and broad.
Great Plains.
Galileo called the dark flat parts on the moon "seas" or "maria" in Latin, although they are now known to be basaltic plains formed by ancient volcanic activity.
I think you're asking about the moon's "mares," which are broad, relatively smooth plains on the lunar surface. The word "mare" is Latin for sea, which is what early astronomers mistook the plains for.
The broad flat valley floors that are carved out by wondering streams are called flood plain and the two methods of the streams eroding the rocks to form the flood plain are down cutting and lateral erosion.
Plains are flat, expansive landforms characterized by gentle slopes and minimal elevation changes. They can be covered in grasses, shrubs, or other vegetation, making them ideal for agriculture. Plains are typically found between mountain ranges or along coastlines.
Maria, or "seas", which is what "maria" means.
The lunar 'seas' are flat plains made up of dried volcanic rock which were orignially lava when the moon was geologically active.
