Geology of Mars. Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.
Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [8] A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars. [9] Layers can be hardened by the action of groundwater.
Geological map of the region around the Tharsis plateau. Extensional and compressional features – e.g., graben and wrinkle ridges – have been mapped and are visible in the image. (USGS, 2014). [1] The Tharsis plateau, which sits in the highland-lowland boundary, is an elevated region that covers roughly one quarter of the planet.

Shaded relief map of the Llano Estacado. Texas contains a wide variety of geologic settings. The state's stratigraphy has been largely influenced by marine transgressive-regressive cycles during the Phanerozoic, with a lesser but still significant contribution from late Cenozoic tectonic activity, as well as the remnants of a Paleozoic mountain range.
The geological history of Mars follows the physical evolution of Mars as substantiated by observations, indirect and direct measurements, and various inference techniques. Methods dating back to 17th-century techniques developed by Nicholas Steno, including the so-called law of superposition and stratigraphy, used to estimate the geological ...
The State Fair of Texas is an annual state fair held in Dallas at historic Fair Park. The fair has taken place every year since 1886 except for varying periods during World War I and World War II as well as 2020, due to the COVID-19 pandemic. [2] It usually begins the last Friday in September and ends 24 days later.
The State Fair of Texas is celebrating its 136th anniversary this year at Fair Park in Dallas from Sept. 30 to Oct. 23. Tickets and season passes are available now on the State Fair website .
