The giant-impact hypothesis, sometimes called the Big Splash, or the Theia Impact, suggests that Luna (the Moon) formed from the ejecta of a collision between the proto-Earth and a Mars-sized planetesimal, approximately billion years ago, in the Hadean eon (about 20 to million years after the Solar System coalesced). The colliding body is sometimes called Theia, from the name of the. Wegener first published his ideas in in a short book called Die Entstehung der Kontinente (The Origin of Continents), and then in in Die Entstehung der Kontinente und Ozeane (The Origin of Continents and Oceans).He revised this book several times up to , and it was translated into French, English, Spanish, and Russian.
Gradually, the lava ocean cooled and solidified, forming the light-colored crust we call the lunar highlands, which still covers 80 percent of the Moon. Lava from the lunar "seas". This chunk of bubble-rich lava, collected by the Apollo 15 astronauts, typifies the surface rock of the dark maria . a. The maria are made of lighter-colored, more felsic rocks than those of the oceanic crust. b. The maria are made of much older volcanic rocks than those of the oceanic crust. c. The maria are intrusive, while the rocks of the ocean crust are extrusive. d. The maria are still partially molten, while most of the oceanic crust is solid.
One of the Apollo 10 astronauts aimed a handheld 70mm camera at the surface from lunar orbit for a series of pictures in this area. In broad terms, the moon has two main components: the dark maria that formed from volcanic activity early in the Moon's history and the light highlands that are the original lunar . chapter 1: petrology and chemistry of terrestrial, lunar and meteoritic basalts: introduction: 2: survey of major basalt types: 5: mafic and.

Centuries ago, early lunar observers thought that the Moon had continents and oceans and that it was a possible abode of life. They called the dark areas “seas” (maria in Latin, or mare in the singular, pronounced “mah ray”). Their names, Mare Nubium (Sea of Clouds), Mare Tranquillitatis (Sea of Tranquility), and so on, are still in use.
The lunar maria were denominated in Latin for terrestrial seas and oceans. Minor craters were denominated in honor of astronomers, mathematicians, and other famous scholars.
A study of the Moon from Robert Hooke's Micrographia of InJohannes Hevelius produced the rival work Selenographia, which was the first lunar atlas. The lunar maria / ˈ m ɑːr i ə / (singular: mare / ˈ m ɑːr eɪ /) are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions.
They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to the naked eye.

Head, Christian Wöhler, Roberto Bugiolacchi, Lionel Wilson, Alexander T. Basile. The Late Heavy Bombardment (LHB), or lunar cataclysm, is a hypothesized event thought to have occurred approximately to billion years (Ga) ago, at a time corresponding to the Neohadean and Eoarchean eras on Earth.
During this interval, a disproportionately large number of asteroids are theorized to have collided with the early terrestrial planets in the inner Solar System, including. Terrestrial oceans and lunar maria book hypothesis is that lunar maria are composed of basaltic matter similar to that of terrestrial ocean basins, and that the lunar continents (bright regions) are composed of siliceous blocks.
INTRODUCTION The Moon's surface is characterized by bright areas covered by ringed structures and great expanses of dark plains. Ocean Science. Biological and Chemical Oceanography; General Oceanography is a deformed Precambrian impact crater analogous to the circular lunar maria.
The petrologic similarity of the maria and terrestrial lopoliths, such as the Bushveld, Duluth, and Sudbury igneous complexes, was suggested inassuming these to be extrusive features. How did the lunar maria form. A) Large impacts fractured the Moon's lithosphere, allowing lava to fill the impact basins.
B) The early bombardment created heat that melted the lunar surface in the regions of the maria. C) Volatiles escaping from the Moon's interior heated and eroded the surface in the regions of the maria. In the science fiction book series "Red Mars, Green Mars, Blue Mars" the author spins a story of "terraforming" Mars with the formation of oceans and a breathable atmosphere by the end of the series.
The author describes a scenario, however, where the inhabitants of this fictional world were able to live relatively normally on most of the world. How did the lunar maria form. A) Volatiles escaping from the Moon's interior heated and eroded the surface in the regions of the maria.
B) The giant impact that created the Moon left smooth areas that we call the maria. C) Large impacts fractured the Moon's lithosphere, allowing lava to fill the impact basins. Definite and very impressive chains of negative forms, Maria, intersect both lunar hemispheres (Fig.
3).At present they are inclined, but in the past (when the axis of rotation was ~30° from the present (Garrick-Bethell et al. ), they made one belt along the alignment mimics the equatorial belt of eight terrestrial rings – one more reason to see the similarity of the Moon.
Stuart Ross Taylor, in Encyclopedia of the Solar System (Second Edition), Mare Basalt Ages. The oldest ages for returned lunar mare basalts are from Apollo 14 breccias; aluminous low-Ti basaltic clasts in these breccias range in age from to billion years.
The oldest basalt from a visible maria is Apollo sample numbera low-K basalt from Mare Tranquilitatis with an age. Our planet's perfect alignment with the Sun and Moon during a total lunar eclipse mimics the geometry of a transiting terrestrial planet with its star. In a new study, Hubble did not look at Earth.
One of the most mysterious lunar features discovered during the Apollo era was Ina, a ~2 × 3‐km depression composed of bleb‐like mounds surrounded by hummocky and blocky terrains. Subsequent studies identified dozens of similar features in lunar maria, describing them as.
This is a list of maria (large, dark, basaltic plains) on the includes other basaltic plains, including the one oceanus as well as features known by the names lacus, palus and modern system of lunar nomenclature was introduced in by Giovanni Battista Riccioli.
Riccioli's map of the Moon was drawn by Francesco Maria Grimaldi, who has a crater named after him. By contrast, precise measurements on lunar samples reveal that the lunar fractionation line is indistinguishable from the terrestrial line to within the analytical uncertainties (Wiechert et al., ).
Any difference between the Earth and Moon must be less than ‰, which translates to a few percent of the difference between Earth and Mars.
Early in the seventies, planetary geologists had already identified peculiar collapse sinkhole-like morphologies in several volcanic areas of Mars and in the lunar Maria (Carr et al., ; Carr, ).These “sinkholes” are often referred to as “collapse” or “pit” chains when they are aligned ().Since these features lack the elevated crater rim and ejecta deposits that are.
The Lunar Magma Ocean (LMO) is the layer of molten rock that is theorized to have been present on the surface of the Lunar Magma Ocean was likely present on the Moon from the time of the Moon's formation (about or billion years ago) to tens or hundreds of millions years after that is a thermodynamic consequence of the Moon's relatively rapid formation in the aftermath.

Note the smooth contours of the lunar mountains, which have not been sculpted by water or ice.

The intense cratering of the lunar highlands and the absence of a similar heavily cratered surface on the Earth were long recognized as due to an early “pregeological” bombardment. In contrast, the lightly cratered basaltic mare surfaces, on which the.
