Good morning, Earthlings!

I have traveled far and wide to look at this week's topic! I present to you the fascinating insight of chaos terrain! What is chaos terrain? We don't know!

No, seriously...we call it "chaos terrain" because it's a geologic nightmare of jumbled mountains and boulders and sometimes ice!

Here are some interesting places and geologic findings about chaos terrain!

1-Mercury! Caloris Baisn is one of the largest craters in the Solar System found on Mercury! It was so large, that shock waves bent the surrounding rock and jumbled it together to form chaos terrain!

2-Mars! It is possible that these areas are formed by past upheavals of water and valley construction all at once!

3-Europa! These are disruptions of the surface cracking under pressures or impacts and then "self-healing" with patches of fresher ice!

4-Pluto! Yes, New Horizons caught some beautiful jumbled glaciers and boulders bordering Sputnik Planitia! How were they formed? We hope to find out!
