Tectonic processes of Pluto by Michael Porteous https://padlet.com/mickester12/ucl9dw2jpq1o evidence for plate activity en-us 2019-04-04 20:37:07 UTC 2026-01-15 16:12:07 UTC hello@padlet.com Tectonics mickester12 https://padlet.com/mickester12/ucl9dw2jpq1o/wish/348725617 Currently there is some evidence that the only tectonic activity on Pluto is extensional tectonics, driven by surface expansion caused by partial freezing of an ocean below the surface. However, there is some evidence of ancient plate tectonics, as valleys, mountain ranges (3500m high), and faults have formed. ( JEFFREY M. MOORE, WILLIAM B.
