Explanation:
The burgess and Hoyt models both try to understand urban land use. Both models have the same assumptions (e.g all land is flat, the importance of centrality, and etc).
When scientists discuss the great oxygenation event, they are referring to a time when the transition from the mildly reducing Archean atmosphere-ocean system to the oxygenated atmosphere and shallow oceans of the early Paleoproterozoic that started between ~2.4 and 2.3 Ga and ended between 2.1 and 2.0 Ga.
- here The Great Oxidation Event, also called the Great Oxygenation Event, the Oxygen Catastrophe, the Oxygen Revolution, and the Oxygen Crisis, was a time interval when the Earth's atmosphere and the shallow ocean first experienced a rise in the amount of oxygen.
- in this event Gradually, the accumulated oxygen started escaping into the atmosphere, where it reacted with methane. As more oxygen escaped, methane was eventually displaced, and oxygen became a major component of the atmosphere.
- The Great Oxygenation Event (GOE) was the creation of free oxygen in our atmosphere. It was caused by cyanobacteria doing photosynthesis

The earth is held in place by the gravitational force from the sun, as it is the largest object within the solar system that will keep the Earth in place.
Answer:
I'm not sure what the question is. If the Icecaps melt (north & south), including glaciers, the water levels will rise, and a mass migration would occur due to the rising Sea levels many countries won't exist anymore! Add a superbug, and it will result in catastrophic mass casualties. Either scenario will have enormous consequences for all of humanity. The reality is it’s already happening now, mass migration from war-torn countries in north Africa and other regions are trying to flee to survive, but it’s not as simple as to go to higher ground. Countries/regions on a higher ground cannot support the influx of refugees; thus, they won’t allow entry, and the people will perish. Every scenario is pointing to a total collapse of the current world and inevietably war. Of course, it’s not the end of the world, but close. Some humans will survive in remote areas, not directly affected by rising water levels or pandemics and war, but it won’t be pretty since most infrastructures will have to be rebuild. It would set humanity set back to the pre-industral area.
