Quaternary period
Explanation:
The last Ice Age on Earth occurred during the Quaternary period. This Ice Age only ended around 10,000 years BC, so very recently. During this period, big portions of the Earth were under ice, with approximately half of North America, as well as half of Eurasia being covered in ice. The mountains around the globe too were covered in glaciers. Because there was so much water trapped in the ice sheets and glaciers, the sea levels were much lower, which opened up lot of land-bridges between the islands and continents, which turned out to be crucial for the human migrations around the globe.
Answer:
It made significantly better predictions of planetary positions in our sky
Explanation:
Of the following statements the one which was not a major advantage of Copernicus's Sun-centered model over the Ptolemaic model is that it made significantly better predictions of planetary positions in our sky. Both the model made similar predictions of planetary position in our sky. In fact the Ptolemaic model was even better than the Copernicus's heliocentric model when it came to positioning of planets.
Your answer would be Tectonic.
Tectonic plates move in various directions, and move slowly. Due to the movement of tectonic plates the earth cracks, and shakes which is called an earch quake. Tectonic plates move constently everyday, and you can't feel it because it's slow. Wehn tectonic plates move quickly, the earth starts to shake. The most common places that have tectonic plates have a higher chance of having an earthquake, even a tusnami.
