Mercury - Surface of Mercury is most similar to the lunar surface, and covered by many craters and basins, suggesting that the planet in the geological dormant for millions of years. The main relief shapes on Mercury are plateaus "moon-like", wrinkled ridges called the dorsum, mountain ranges, basins, canyons.
The ground of Mercury has crumbled due to the impact of meteorites and soil erosion due to rapid daily variations in temperature. Overall knowledge of the geology and geomorphology of Mercury are based for now only on research spacecraft Mariner 10 in 1975 and the first telescope from Earth. Consequently, Mercury is still unknown like the inner planets of the solar system, and the analysis …show more content…
Below the lithosphere is astenosfera, that which is the inner part of Manti. Astenosphere is superheated and acting as an extremely viscous liquid. The biggest Tectonic plate is Pacific Ocean plate.
Lithosphere essentially floats on the asthenosphere broken the tectonic plates. There are two types of boards: the ocean (eg. Slab Pacific Ocean) and continental plates. These plates are the segments which are moving relatively one in relation to each other and at the same time can be formed from the following boundaries of tectonic plates: a convergent, divergent and transform.
Tectonic …show more content…
Due to the small average density which suggests that it is not composed of a solid stone, but rather a mixture of rock and ice, in the richness of the carbon, as well as the low albedo, Fobos most resembles the asteroids of type D. However, it is thought that earlier in the Martian system any more objects the size of Phobos and Deimos, which are not native asteroids, but were created by the collision of Mars with a large planetesimal. Its dimensions 27 × 21.6 × 18.8 km and a mass of 1.08 × 1016kg Phobos is one of the least satellites of the solar system. It is not spherical, but very irregular shape which is characteristic of asteroids. It is extremely dark body. Infrared recording of Phobos show large differences in temperature between day and night by satellite, and fast heating and cooling is the result of the existence of a thick layer of dust. Most notably, Stickney crater diameter of 10 km. from which extend the chain of small craters which are conjoined I the opposite side of the satellite. It is believed that the smaller craters formed by debris impact that created the crater Stickney. The deepest around the crater Stickney (90 m) long and up to 700 m, while other chains crater depth 10 - 20 m and a width of 100 - 200 m. Blow he suffered Fobos almost broke the satellite. Phobos has no
