The Text Book title- is the correct answer
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.
It's is called sustainability
1.51 is the partial pressure of gas Y. as At 300 K, the volume of the flask that contains a gaseous mixture of two gases, X and Y, is 20 L. If the total pressure of the container is 2 atm and 0.1.
<h3>What is
gaseous mixture?</h3>
The gaseous combinations that are properly considered in this book are blends of different ingredients that may or may not vary outside of certain bounds.
These gases often belong to the category of "fuel gases," and each gas is any of a number of fuels that are gaseous at normal temperatures and pressure.
Thus, 1.51 is the correct answer.
