The first planet closest to the Sun, Mercury, has a surface geology which is quite rocky, with heavy amounts of craters, boulders, and a lot of pulverized dust. It lacks in atmosphere, due to its moderate day-night variations, particularly in heating by solar energy, and its temperate weather swings as a result of that energy. Temperatures on Mercury range from low (90 Kel.) to high (700 Kel.) though, despite its many observations, it is however quite dead, and it has been for some time.
An interesting feature of Mercury is its magnetic field. As a planet with no cloud activity, no visible signs of existing rivers, dust storms (despite the amount of dust present) and or any other aspects pertaining to weather, this makes Mercury …show more content…
Earth:
Earth's tectonic plates (or plates which float separately and independently of the hotter mantle which sits below them) are categorized into three major categories, these being: Primary (Major), Secondary (Minor) and Tertiary (or, micro-plates.) The seven major (or, any plates which range over at least 10 million kilometers) plates are: African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate. These are also the primary plates which formulate the planet's Lithosphere.
The three major categories of plate activity are Divergent, which is where plates move apart from one another, Subduction, wherein an oceanic plate moves beneath a continental plate, and which usually causes the largest amount of volcanic and earthquake activity, and finally, Transform, which is where plates slide back and forth against one another. A result of this activity is that the Earth and its contents were once known as a single continent under the name Pangaea, and which is now comprised of several, separate continents, or areas of land, which continue to move to this day, each time the tectonic plates have …show more content…
Their names derive from the sons of Ares, who was the Greek and Roman god of War. The Romans would call him Mars. The names of the moons are Phobos, which correlates to Fear, and Deimos, which represents Panic. Their mother was the goddess Aphrodite, the Greek goddess of Love, which is also the name derivation for the planet Venus. In size, these moons are little more than rocks, in their scale, and are thought to be trapped, by the planet's gravitational pull. As discovered by an American Muggle astronomer, Asaph Hall, in 1877, these two moons orbit closely to Mars, and are about only tens of kilometers across in
