The archaeologists need to know about the rain patters in the period and place where the Maya existed because the rain was crucial about the growth and well being of the crops that this civilization used. A longer drought than usual can make a huge problem with starvation, and that can be a key reason for the fall of one of the greatest civilizations in the Americas.
''The Maya world probably had too many people'' refers to the food supplies available and their reserves, and the amount of people that were using them, so it is thought that the Maya had too many people that produced and used limited amount of food, so their reserves were very low and would have lasted for a very short term period of time.
Well The Nile River flooded annually; this flooding was so regular that the ancient Egyptians set their three seasons Inundation, or flooding, Growth, and Harvest around it.
This annual flooding was vital to agriculture because it deposited a new layer of nutrient-rich soil each year. In years when the Nile did not flood, the nutrient level in the soil was seriously depleted, and the chance of food shortages increased greatly. Food supplies had political effects, as well, and periods of drought probably contributed to the decline of Egyptian political unity at the ends of both the Old and Middle Kingdoms.
Answer: emigration or increase in death rate
Explanation:
Many factors can modify the animal population in a specific area.
Amphibian populations are affected mostly by changes in temperatures, altered dry season rainfall, and modified leaf litter depth.
Considering the options provided, only emigration and an increase in death rate could explain the decrease of the frog population.
Immigration and an increased birth rate would result in the population growing, not decreasing.
The best answer is - every aspect of our electric life.
Westinghouse was an an inventor and entreprenur that lived around the same time when Thomas Alva Edison lived. I't is also not surprising to mention that they were grand rivals, as they were inventing things in the same field. Namely, Westinghouse developed a system that distributes electricity based on alternating current which is also the type we still use today and thus surpassed the idea of Edison which was based on the idea of direct current.
