List Of Geological Features On Mercury
List of geological features on Mercury is an itemization of mountains, valleys, craters and other landform features of the planet Mercury. Different types of features are named after different things: Mercurian ridges are called dorsa, and are named after astronomers who made detailed studies of the planet; valleys are called valles, and are named after ancient abandoned cities, towns, and settlements; crater chains are called catenae and are named after radio telescope facilities; plains are called planitiae, and most are named after mythological names associated with Mercury; escarpments are called rupes and are named after the ships of famous explorers; long, narrow depressions are called fossae and are named after works of architecture; bright spots are called faculae and are named after the word snake in various languages.

Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caloris Montes
The Caloris Montes (Latin for "Heat's Mountains") are a range of mountains on Mercury. They are a system of linear hills and valleys that extend more than 1000 km to the northeast from the mountainous rim of Caloris Basin in the Shakespeare quadrangle (H-3). The range consists of numerous rectilinear massif In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a ...s 1 to 3 km high and about 10 to 50 km long, mostly elongated radially from the center of the basin and separated by hackly-floored, radial troughs and gouge-like structures. The surfaces of the massifs are hackly. They are best developed along the inner edge of the basin where steep inward-facing scarps are common, grading outward into smaller massifs and blocks. The range marks the crest of most prominent ring structure ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cahokia Mounds
The Cahokia Mounds State Historic Site (Smithsonian trinomial, 11 MS 2) is the site of a Pre-Columbian era, pre-Columbian Indigenous peoples of the Americas, Native American city (which existed 1050–1350 CE) directly across the Mississippi River from modern St. Louis, St. Louis, Missouri. This historic park lies in south-western Illinois between East St. Louis, Illinois, East St. Louis and Collinsville, Illinois, Collinsville. The park covers , or about , and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about and included about 120 Earthworks (archaeology), earthworks in a wide range of sizes, shapes, and functions."Nomination – Cahokia Mounds State Historic Site, Illinois" ''US Worl ...
