What are ruined lunar craters?

Ruined craters are ones that have been formed in the early stages of the Moon’s history but have been devastated subsequently by later volcanic eruptions and crustal disturbances. The outlines of some of the heavily ruined craters are barely recognizable.

 

 

 

 

 

 

 

What are lunar clefts?

A lunar cleft has the appearance of a river bed on Earth. This is a mere coincidence since there is no water on the Moon and appearances can be deceptive. One of the impressive clefts, the great Heroclotus Valley clefts, is 500 m deep and winds impressively like a river gorge across the plain.

 

 

 

 

 

Where did the first moon craft “Eagle” land?

“Eagle” landed on Mare Tranquillitatis (the sea of tranquility) at a spot appropriately named “Tranquillity Base”.

 

 

 

 

 

 

 

 

 

What are crater lets?

Craterlets are tiny craters ranging in diameter from a few meters to about twenty kilometers. The Moon has plenty of such crater lets.

 

 

 

 

 

 

 

 

 

What are twin craters?

Twin craters are those that occur close together, sometimes separated and sometimes joined together. In some cases, one crater crosses the boundary of another crater causing damage to it. Since large craters have been formed earlier, it is usually the small ones formed later which intrude and do the damage.
