intercrater plains |
plains of craters on the surface of mercury |
|
|
scarp |
a type of cliff not believed to have been formed by volcanic or other geological means. istead, may have happened when the surface cooled and split after the bombardment of the surface
|
|
|
shield volcanoes |
wells of slowly oozing volcanoes on the surface of venus
|
|
|
coronae |
largest volcanic formations on venus. aka shield volcanoes |
|
|
runoff channels |
found in southern highlands of mars. twisting channels that merge into larger wider channels
believed to have once carried water from the mountains into the valleys |

|

|
secondary atmospheres |
made up of gasses from volcanic activity and time. end result of the second atmosphere is what we observe today.
|
|
|
carbon cycle |
the recycling of CO2 from the atmosphere to planetary surface venus = too much CO2 put out into atmosphere and not enough absorbed by rocks/surface mars = too much CO2 absorbed by rocks/atmosphere and not enough put out into atmosphere earth = goldilocks zone |
|
|
runaway greenhouse effect |
essentially, venus is a runaway greenhouse effect. sooo much light/heat has heated the surface to the point the CO2 has become a dominant factor in the atmosphere. too much CO2 output, not enough absorbed |
