Scientists hypothesize that the K – Pg extinctions were caused by one or more catastrophic events, including at least one asteroid impact ( especially the one that created the Chicxulub crater ) or increased volcanic activity.

The reduced gate mass makes their wire bales less prone to ' gate flutter ,' a dangerous condition created by irregular impact forces generated by the climbing rope or contact with hard surfaces in a fall which momentarily opens the gate ( and both lowers the breaking strength of the carabiner when open and potentially allows the rope to escape ).

At this time a number of researchers, most notably Eugene M. Shoemaker, ( co-discoverer of the comet Shoemaker-Levy 9 ), conducted detailed studies of a number of craters and recognized clear evidence that they had been created by impacts, specifically identifying the shock-metamorphic effects uniquely associated with impact events, of which the most familiar is shocked quartz.

Two impacts 12 hours apart on July 19 created impact marks of similar size to that caused by fragment G, and impacts continued until July 22, when fragment W struck the planet.

Moreover, these unconventional troops created a psychological impact over the enemy, which was not used to dealing with horse troops, having no training or strategy to face them.

Bowie's impact at that time, as described by biographer David Buckley, " challenged the core belief of the rock music of its day " and " created perhaps the biggest cult in popular culture.

Mediaite columnist Paul Levinson noted that " The Monkees were the first example of something created in a medium – in this case, a rock group on television – that jumped off the screen to have big impact in the real world.

This Act was created to promote employment of older persons based on their ability rather than age ; to prohibit arbitrary age discrimination in employment ; to help employers and workers find ways of meeting problems arising from the impact of age on employment because in the face of rising productivity and affluence, older workers find themselves disadvantaged in their efforts to retain employment, and especially to regain employment when displaced from jobs ; the setting of arbitrary age limits regardless of potential for job performance has become a common practice, and certain otherwise desirable practices may work to the disadvantage of older persons ; the incidence of unemployment, especially long-term unemployment with resultant deterioration of skill, morale, and employer acceptability is, relative to the younger ages, high among older workers ; their numbers are great and growing ; and their employment problems grave ; and the existence in industries affecting commerce, of arbitrary discrimination in employment because of age, burdens commerce and the free flow of goods in commerce.

The largest crater observed on Triton thought to have been created by an impact is a 27 km-diameter feature called Mazomba.

It has been suggested that other significant objects may have been created by the impact, which could have remained in orbit between the Earth and Moon, stuck in Lagrangian points.

The impact in this scenario would have created a magma ocean on Earth and the proto-Moon with both bodies sharing a common plasma metal vapour atmosphere.

As with Mimas's crater Herschel, the impact that created Stickney must have nearly shattered Phobos.

The grooves are typically less than deep, wide, and up to in length, and were originally assumed to have been the result of the same impact that created Stickney.

It cannot be created by volcanic action ; the only known mechanism of creating it is through an impact event ( or artificially through a nuclear explosion ).

The impact created an inverted stratigraphy, so that the layers immediately exterior to the rim are stacked in the reverse order to which they normally occur ; the impact overturned and inverted the layers to a distance of one to two kilometers outward from the crater's edge.

One of the great debates in advance of the impact was whether the effects of the impact of such small bodies would be noticeable from Earth, apart from a flash as they disintegrated like giant meteors.

# Accretion and differentiation: a period of planetary formation until giant Moon-forming impact event.

In a giant storm, caused by air escaping through a hole in the Ring floor due to meteor impact, Teela is blown away in an unknown direction.

In 1921, the Russian mineralogist Leonid Kulik, visiting the Podkamennaya Tunguska River basin as part of a survey for the Soviet Academy of Sciences, deduced from local accounts that the explosion had been caused by a giant meteorite impact.

The giant impact hypothesis states that the Moon was formed out of the debris left over from a collision between the Earth and a body the size of Mars, approximately 4. 5 Gya ( four and a half billion years ago ).

The giant impact hypothesis is the currently-favoured scientific hypothesis for the formation of the Moon.

There remain several questions concerning the best current models of the giant impact hypothesis, however.

The energy of such a giant impact is predicted to heat Earth to produce a global ' ocean ' of magma ; yet there is no evidence of the resultant planetary differentiation of the heavier material sinking into Earth's mantle.

At present, there is no self-consistent model that starts with the giant impact event and follows the evolution of the debris into a single moon.

Indeed, one of the attractive features of the giant impact hypothesis is that the formation of the Moon fits into the context of the formation of the Earth: during the course of its formation, the Earth is thought to have experienced dozens of collisions with such planet-sized bodies.

The Moon-forming collision would have been only one such " giant impact " and, perhaps, the last.

Regardless of the speed and tilt of the Earth's rotation before the impact, it would have experienced a day some five hours long after the impact, and the Earth's equator and the Moon's orbit would have become coplanar in the aftermath of the giant impact.

Instead, they proposed that in the aftermath of the giant impact, while the Earth and the proto-lunar disk were molten and vaporized, the two reservoirs were connected by a common silicate vapour atmosphere, and that the Earth – Moon system became homogenized by convective stirring while the system existed in the form of a continuous fluid.

Indirect evidence for the giant impact scenario comes from rocks collected during the Apollo Moon landings, which show oxygen isotope ratios identical to those of Earth, which can be explained if the Earth – Moon system experienced turbulent mixing in the aftermath of the giant impact, as discussed above.

In addition, the highly anorthositic composition of the lunar crust, as well as the existence of KREEP-rich samples, gave rise to the idea that a large portion of the Moon once was molten, and a giant impact scenario could easily have supplied the energy needed to form such a magma ocean.

For example, the giant impact hypothesis implies that a surface magma ocean would have formed following the impact.

* The ratios of the Moon's volatile elements are not explained by the giant impact hypothesis.

At the Alphonsus, three scientific objectives were determined to be of primary interest and paramount importance: the possibility of old, pre-Imbrium impact material from within the crater's wall, the composition of the crater's interior and the possibility of past volcanic activity on the floor of the crater at several smaller " dark halo " craters.

Observers soon saw a huge dark spot after the first impact.

This and subsequent dark spots were thought to have been caused by debris from the impacts, and were markedly asymmetric, forming crescent shapes in front of the direction of impact.

The impact of one of its fragments created a giant dark spot over 12, 000 km across, and was estimated to have released an energy equivalent to 6, 000, 000 megatons of TNT ( 600 times the world's nuclear arsenal ).
