Question

There are four categories of surface modification on the terrestrial planets: cratering, volcanism, tectonics, and erosion. a. Which of these did you NOT observe on Venus? b. Venus has a very thick atmosphere, but at its surface, the gas is moving at only 0.3 to 1.0 meters per second (0.7 to 2.2 mph). How does this explain your answer to the question above? You looked at images of Venus "as seen from above". Below left is a simulated picture of what a corona would look like from an airplane and below right is a schematic of how coronae form. Use the schematic to describe, in words, why a corona has concentric cracks (as you saw in the lab) as well as why it looks like a fallen souffle (in the image below). (And don't worry about the distinction between the three types of coronae: give a general description of their appearance and formation!)

Explanation / Answer

1 a- there is no erosional affect present of venus.

b) the speed of moving gas shoes that the speed is not enough for erosion of rock surface erosion.

2) surface of venus is dominated by patterns of basaltic volcanisation which cause cracks, and after settling of the valcano it took the shapes like fallen souffle.

a) aine corona- are circular bulges formed vy volcanic activity.

b) baltis vallis- corona formed by lave which flows and collapsed after motion lava drained away.

c) domes type corona- associated with the volcanic activity in this situation lava must have come out of it and made such dome type structure.
