In urban areas, there are more people, therefore not a lot of farmland. (that eliminates C) If city buildings don't allow flood waters to recede, that could be dangerous in many ways. (So A is still a reasonable answer) If most cities are built in flood zones, there should be some form of shelter if houses aren't safe. Pollutants and diseases being carried in water are already dangerous, but easier to spread with rapid flood waters that are sweeping everywhere. So your best answer would be either A or B.
The way the moon effects the tides on earth is the gravity between the earth and moon and I would go into more detail but that would take all day
Answer:
1. giant impact forms moon
2. end of heavy bombardment
3. early life (based on fossil evidence))
4. oxygen buildup in atmosphere
5. earliest mammals
6. dinosaurs go extinct
7. earliest humans
Explanation:
The Earth has a very interesting past, with lot of changes and turnarounds in it. If we sum it up quickly, we can say that soon after the Earth formed and collided with another large space object, part of the Earth was torn away, which eventually formed the moon. The Earth was constantly bombarded by meteorites and asteroids, but that came to an end as the atmosphere was becoming denser and denser. The first life started to develop in the oceans in the form of cyanobacteria, which used photosynthesis, and were constantly releasing oxygen, building it up int he atmosphere. The oxygen changed the living conditions, enabling the life to thrive and diversify. The dinosaurs and mammals eventually came on the scene, with the dinosaurs coming first by around 20 million years, giving them the edge to become the dominant life form. The mammals lived in the shadows until the dinosaurs existed, but their reign ended with a large meteorite collision. This prompted the quick evolution and diversification of the mammals, quickly becoming the dominant life form, and just few million years ago they gave rise to the earliest human ancestors, the hominids.
