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.
1. Geography affects the settlement of future civilizations when taking into account the resources provided in different areas. Lusher areas with a larger range of edible plants and animals as well as water are a very appealing location to start a settlement. Of course, different groups of people with different lifestyles will be searching for varying resources to start their society, or to just stay temporarily if they choose nomadic existence.
2. Climate majorly affects settlements depending on if they want to grow crops, as well as the type of crops. Another factor dealing with climate in relation to settlements is if it is a bearable climate to live in long term without higher death rates due to temperatures.
Answer:
The gravitational potential will change more on earth.
Explanation:
The gravity on the moon is only 17% of that of earth's because the earth has way more mass. Since the gravitational potential depends on the mass of the human and the height of the ladder, and both things will remain equal, no matter where they are, so we could assume that the gravitational potential energy will change more on earth.
