Moon Creek is used to describe a dark and slender fissure on the moon surface similar to a stream on the earth. It is usually used to describe any narrow and long groove on the moon surface similar to a riverbed.These moonstreams are usually several kilometers wide and hundreds of kilometers long.According to the nature of the Moon Creek, it can be divided into three types: meandering Moon Creek, bow shaped Moon Creek and straight Moon CreekMoonIt is of great significance to have a history of development.
MoonIn addition toMoon Sea, Moon Land, Mountains, Craters andCrateretc.GeographyIn addition, some dark cracks can be seen in many areas of the moon surface, stretching hundreds of kilometers, thousands of meters, or even ten kilometers wide. They look like valleys on the earth. The wider of these landforms is calledMoon ValleyThe slender one is called Yuexi.
On the surface of the moon, there is a dark and slender fissure, which is similar to the earth's stream, called Yuexi.The earliest Yuexi River was built byNetherlandsThe scientist Huigengs discovered it in 1684 and named it Huigengs Moon Creek.[2]

Based on the analysis of image data and morphological characteristics, Yuexi can be divided into four basic types:
(1) Zhiyue Brook;
(2) The bow shaped moon stream is generally believed to be formed under the action of the tensile stress of the moon chasm;
(3) Irregular Moon Creek, mostly seen at the bottom of impact crater;
(4) The winding Moon Creek is mostly found in the flat area at the lower part of the valley, such as Hadley Moon Creek on the eastern plain of Yuhai, which is one of the clearest curved Moon Creeks on the moon surface.[2]

Scientists speculate that the meandering Moon Creek and Zhiyue Creek may bevolcanoThe lava flow formed by the action flows according to the topographic and structural characteristics, and some tectonic stresses can also form the moon stream, such as the bow moon stream.The cracks formed by meteorite impact are the main reason for the formation of irregular moon streams.
Hadley Moon Creek on the eastern plain of the Rainy Sea is one of the clearest curved Moon Creeks on the lunar surface. It is located near the landing site of Apollo 15 spacecraft, so people have studied it most clearly.Hadley Moon Creek is more than 100 kilometers long, 1.5 kilometers wide and 400 meters deep.The rock outcrops on the two walls of the Moon Creek are very fresh, showing the material composition and tectonic evolution history of the moon surface.From the profile, the upper part is the lunar surface soil, up to 5 meters thick, and the lower part is rock blocks and debris breccia layers of different thicknesses, which were formed by impact or volcanism in different periods, and the lower part is the piedmont deposits and hard and complete bedrock.
Through detailed analysis of the image of the moon valley and moon stream, field investigation and analysis of rock samples, scientists believe that the moon valley and moon stream have a variety of formation modes: the moon valley and curved moon stream similar to the V-shaped valley on the earth may have been caused by the flow of water about 4 billion years ago, the early stage of the formation of the moon;Some moon streams and moon valleys may also be formed by the flow of lava flows generated by volcanic eruptions;Some moon streams and valleys are the remnants of the radiation left by meteorites when they hit the moon surface;Individual Yuexi and Yuegu are even cracks caused by many small moon pits distributed in rows, such as the famous Hijinus fissure in the center of the moon surface.[2]
