@Regranned from @bbcbrasil - Este é o lago Manicouagan, no Canadá, uma das maiores crateras abertas pelo impacto de um corpo celeste na Terra. De acordo com a @NasaGoddard, o lago surgiu em torno da elevação central da estrutura central do impacto, que tem um diâmetro de cerca de 70km e se compõe de fragmentos de minerais. Ao longo das eras, erosão e gelo reduziram o tamanho da cratera. Especialistas calculam que o impacto que formou a cratera tenha acontecido há 212 milhões de anos, e algunsd dizem que ele teria sido responsável por uma extinção em massa que teria acabado com metade dos seres vivos no planeta. Hoje, o Manicouagan serve como reservatório d'água para Quebec e como uma das regiões mais importantes para a pesca do salmão atlântico.

Today's @dictionarycom Word of the Day is "astrobleme," a scar on Earth's surface produced by the impact of a meteorite or asteroid.

Lake Manicouagan in northern Quebec, Canada, lies in one of the largest impact craters still preserved on Earth's surface. The lake itself surrounds a central uplift of the impact structure, which is about 70 kilometers in diameter and composed of broken fragments of minerals and rock. Overtime glaciation and other erosional processes have reduced the size of the crater.

The impact that formed Manicouagan is thought to have occurred about 212 million years ago, and some scientists believe it may have been responsible for a mass extinction that wiped out more than half of all living species. Today Lake Manicouagan serves as a reservoir and is one of Quebec's most important regions for Atlantic salmon fishing.
