The Manicouagan impact crater is one of the largest impact structures still preserved on the surface of the Earth and is classified as a complex meteorite crater. It is in the Côte-Nord region of Québec, Canada. The five craters form a chain, indicating the breakup and subsequent impact of an asteroid or comet,[5] like the impacts of Comet Shoemaker-Levy 9 on Jupiter in 1994.

Mount Fuji has a summit crater. The crater was formed by an impact of the asteroid that could be up to 5 km large. Like a pebble creating ripples when dropped into water, the crater has concentric rings formed by shock waves transmitted by the impact. It is in the Côte-Nord region of Québec, Canada. It is in the Côte-Nord region of Québec, Canada. Any rocky body floating in space, with a size ranging from a few microns to 10 meters, is known as a meteoroid. It is 65 kilometers (40 miles) in diameter, but it is worth remembering that this is small compared with some of the larger lunar structures that measure more than 600 km (375 miles) across. Its inner ring is its most prominent feature. It is the largest preserved impact crater on Earth. Its inner ring is its most prominent feature. The diameter of the structure is 100 km.

Manicouagan Reservoir: the lake is the combined product of one of the largest known impacts on Earth, the The Dellen crater forms a round lake system consisting of two lakes, Northern Dellen and Southern Dellen. The impact locations have moved large distances in the intervening 214 million years. It was formed following the impact of a 5 kilometres (3.1 mi) diameter asteroid which excavated a crater originally about 100 km (62 mi) wide, although erosion and deposition of sediments have since reduced the visible diameter to about 72 km (45 mi). The part of a meteor that survives the burning on descent and arrives intact on the planetary surface is a meteorite. It is the earth's fifth largest confirmed impact crater.[4]. It is the earth's fifth largest confirmed impact crater.[4]. [1], It was caused by the impact of a 5 km (3 mi) diameter asteroid about 215.5 million years ago,[2] in the Upper Triassic.

Formed during a surely tremendous impact about 200 million years ago, the present day terrain supports a 70-kilometer diameter hydroelectric reservoir in the telltale form of an annular lake . Because of the crater’s young age and the dry climate Meteor Crater is the best preserved impact crater on Earth. Volcanoes can cause craters when the magma hits into the water and causes the … The Manicouagan impact crater looking east as seen from GOZooM. The Manicouagan crater is the sixth-largest confirmed impact crater known on earth. The small one is the meteor crater.

The International Space Station was orbiting 258 miles above Canada when an Expedition 59 crew member photographed Manicouagan Crater (right center) and the St. Lawrence River in Quebec. We use U-Pb zircon dating to test whether the bolide impact that created the Manicouagan crater of Quebec also triggered mass extinction at the Triassic/Jurassic boundary. The age of the impact is provided by zircons from the impact melt rock on the crater floor; we show that the zircons yield a U-Pb age of 214 ±1 Ma. This is a complex crater because it has a peak in the center. The annular moat, prominent in space images, fills a ring where impact-brecciated rock was once eroded away by glaciation.

The Manicouagan crater is one of the largest known asteroid impact craters on Earth. This huge annular (circular) lake was shaped by a number of factors, earliest of which was an asteroid strike an estimated 211 million years ago which created an impact crater over 60 miles across. The rocks of the Witwatersrand Basin, Ventersdorp Lava, Ghaap Dolomite, and Pretoria Subgroup were originally deposited in a nearly horizontal position but were folded and deformed by the impact.
