Document Summary

Compare the earth and venus in terms of size, density, atmosphere, and other characteristics. Describe the surface of venus as seen from landers. The colour as seen on the surface of venus is golden yellow due to venus" thick atmosphere. Without the atmospheric effects, the colour is grey and brown. Explain how the magellan mission could see beneath the clouds to the surface of venus, and what factors affect how the surface looks using radar. Describe the differences between lowlands, uplands and highlands. Mean planetary radius, 6052 km = 0 km elevation . State the evidence for venus having a differentiated interior. List the main tectonic features on venus, and whether they represent compression or extension. The surface of venus is highly deformed , as evidenced by extension, compression, doming, and depression. 100 - 200 km wide, thousands km long, 1 km high. Extensional grabens superimposed on compressional ridges and troughs.
