Answer:
They found evidence of an impact crater in Mexico
Explanation:
The K-Pg boundary is the boundary that separates two periods, but also two eras. The two periods that are separated by this boundary are the Cretaceous and the Tertiary, while the two eras are the Mesozoic and the Cenozoic. The boundary is marked by a mass extinction, and the scientists started to hypothesize as to why it happened. There were numerous different theories, but a clue in Mexico, or rather right next to the Yucatan Peninsula, shed new light on it. The scientists found an impact crater, formed either by a large asteroid or a comet. Such an impact would have easily caused sudden and drastic changes on the Earth, killing of the majority of the species. This impact released such a big amount of energy that it killed everything in the surrounding area in seconds. On top of that, it caused an extremely hot wave of air across the whole planet, killing many more organisms. It managed to trigger most of the volcanoes to erupt, as well as the earthquakes, causing also very large tsunamis. The sunlight got blocked for quite some time from all the aerosols in the atmosphere as well. This resulted in a mass extinction of the dominant species, like the dinosaurs, but it opened up the terrain for the evolution of the others, like the mammals.

Answer:
The western and central European section of the plain covers all of western and northern France, Belgium, The Netherlands, southern Scandinavia, northern Germany, and nearly all of Poland; from northern France and Belgium eastward it commonly is called the North European Plain.
Explanation:
The North European Plain is a European region that covers Denmark, Poland, Germany, Belgium, Holland, and small parts of northern France and the Czech Republic. Some research accounts also include the southern United Kingdom, east Russia, Baltic States like Estonia, Latvia, Lithuania, and Belarus as part of this expansive plain. The North European plain also has lowly elevated plains tucked between the Central European Highlands on the south and on the coastlines of the Baltic Sea and North Sea to the north. The Baltic and the North Sea are divided by the North Jutland Peninsula which is also the nation of Denmark. The Great European Plain is formed where the North European Plain connects to the East European Plain. The Northern European Plain also occupies the territory under the Baltic Sea. Due to the plain's unique surface features, its geological structures are keenly studied by researchers.
Features
As part of the Great European Plain, the North European Plain lies below 500 feet in altitude, and has a relatively flat terrain. As a result, drainage is poor and frosty deposits cover much of the region and plain. The North European Plain also has several rivers like the Rhine, Oder, Weser, Elbe and Vistula. Along the Rhine River in the Netherlands, there is a well developed transport system, and a vibrant agricultural area making the area around it be densely populated. The plain is amongst the most fertile lands that are utilized for commercial farming in the world. There are also tiny farms strewn in the countryside of the North European Plains. The temperate climate and the average amount of rainfall in the North European Plain allows for growth of seasonal crops like maize, wheat, and rye. This makes the plain in the North European wheat belt region. Due to the plain’s fertility and flat terrain, it is among the most densely populated territories in Europe. The rivers that crisscross the North European Plain also draw in a large human population due to guaranteed water supply.
