Scientists once believed there were volcanoes on the Moon due to the presence of features resembling volcanic formations, such as large, smooth plains called maria, which were interpreted as ancient lava flows. Observations of the Moon's surface, including its irregular topography and the presence of certain geological features, led to hypotheses about volcanic activity. Additionally, the lack of significant erosion suggested that these features might be relatively young, supporting the idea of past volcanism. However, further studies revealed that these formations were primarily the result of impact cratering rather than volcanic processes.

Why did scientists once think there were volCANOES ON THE MOON?

The reason that this was that it was once the only thing that scientists could use to explain why the moon had so many craters on it (which we now know to be the product of meteorite and asteroid collisions).


What did chemist learn about the mons surface by analyzing moon rocks?

The rocks were similar to rocks formed by volcanoes on Earth, suggesting that vast oceans of molten lava once covered the moon's surface.

How many volcanoes are dangerous on earth?

I think any volcano is potentially dangerous. It was once thought that volcanoes were extinct but now scientist think volcanoes are active or dormant. So any volcanoe could erupt and be dangerous. Some are more likely to than others.

How do scientist know that the Moon's surface was once hot?

Because the moon was once part of planet that colided into another planet at thousands of miles per hour and then the moon broke of. The part that broke off (the moon) was digging in from the planets crust to the outer core which was thousands of degrees hot.

What word does scientist use for when a volcano is asleep?

Active volcanoes: are those that erupted lava,gases ,cinder,pumice,etc in the historic pass.Eg: Mt.St.Helena Dormant volcanoes: are those which erupted in the past and are likely to erupt again after remeaining inactive for fairly long periods. These are "sleeping" volcanoes which may become active once again. eg: Mt.vesuvius.Extinct volcanoes: are those volcanoes which were active in the remote geological periods. Eg: Mt.Kenya
