Mercury - surface geology

Mercury is a very gray planet, which houses no living creatures or any ‘life’ in General. Mercury's surface is covered in impact craters, basaltic rock and smooth plains, many of them caused by what they believe is flood volcanism. Other features include vents which seem to be the cause of magma-carved valleys, often-grouped irregular-shaped, termed "hollows" that are believed to be the cause of collapsed magma chambers throughout the planet. The biggest crater on mercury was named Caloris Basin, and it has a diameter of 1550 km. Overall, about 15 impact basins have been identified on the part of Mercury that they were able to get a clear picture of. Some impact craters on Mercury are not very round, irregular shaped depressions or pits, and these are called ‘pit- floor’ craters.

Theclouds fly around the top of the planet every four days, but wind speeds drop closer to the planet’s surface. The Winds on Venus move at about 224 mph and it keeps the clouds constantly in motion. On Venus, most of the sun's heat fails to make it through the heavy atmosphere. Although Venus and earth are very close to the same size, the air on Venus is about 90 times heavier then the atmosphere on earth, which would mean it would be very similar to driving 3,000 feet under the
