All parts of Earth are touched by sunlight at some point. Not so on the moon. Some parts of the moon – craters near the lunar poles – lie in permanent shadow while other nearby regions remain sunlit for the majority of the year. Bright areas and streaks, dark areas, and circular features can be distinguished easily even with the naked eye, just use your telescope.
These are some of the craters able to be found on the moon. During my Zoouniverse observations i found a lot of impact and highland craters, as well as dome craters.
- Highlands - bright, extensively cratered areas of igneous rocks rich in the mineral plagioclase and breccias (rocks actually made of broken pieces of many rocks smashed back together again).
- Maria - dark areas covered by lavas of the volcanic rock type called basalt.
- Impact crater - roughly circular hole created when something struck the surface.
- Terraced crater walls - steep walls of an impact crater with stair steps created by slumping due to gravity and landslides.
- Central crater uplift - mountain in the center of large (>40 kilometer diameter) impact craters.
- Crater ejecta - material thrown out from and deposited around an impact crater.
- Ray - bright streak of material blasted out from an impact crater.
- Multi-ringed basin - huge impact crater surrounded by circular mountain chains.
- Lava flow - a break out of magma from underground onto the surface.
- Rille - channel in lunar maria formed as an open lava channel aor a collapsed lava tube.
- Wrinkle ridge - long, narrow, wrinkly, hilly section in maria.
- Cinder Cone - low, broad, dark, cone-shaped hill formed by explosive volcanic eruption.
- Dome - low, circular, rounded hill suspected to be a volcanic land form.
I found many craters that had a shadow to the left of the crater.
I also found many fresh white craters, which are craters that are in the developing stages.
Go to Zooniverse.org to try your own astronomical activities!!
Im having trouble with the "number of classifications/observation" counter on the website, i observed at least 25 different screen shots and classified them but it still says 0 :(
Great write-up (I'm not surprised). Show me your zooniverse site in class and we can get you points for this work.
ReplyDeleteDid you get your 25 observations yet?
