Answer:
The big number of people fleeing from Syria may have very negative demographic and economic implications for the country.
Explanation:
Syria is a country in war, both with armed forces inside and with armed forces from other countries. The war is going on for quite some time now, and it has led to the devastation of most of the country. Being afraid for their lives and seeing that there wouldn't be good conditions for living in the country for decades to come, millions of people have been on the move.
With millions of people already gone and millions trying to migrate out of the country, Syria will face a very big problem in the future. It is rapidly losing the young and middle aged population, which is the population that is able to have children and it is the population that has the biggest economic contribution. Also, the highly qualified labor force has almost entirely left the country. Apart from the sharp decline in the population, this will also result in a dramatic drop in birthrates, aging population, lack of labor force, brain drain, and the economy will suffer badly, which in turn will result in more people moving out of the country.
The Pleistocene often colloquially referred to as the Ice Age) is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the world's most recent period of repeated glaciations. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology.

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:
Cuando la tasa de natalidad supera con creces la tasa de mortalidad, la población se dispara. Duplicar el tiempo es la cantidad de tiempo que tarda una cantidad en duplicarse y se utiliza en demografía para proyectar cambios futuros en el tamaño de la población.
