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: Igneous Rock
Explanation: Radiometric dating is used to date rocks by measuring the decay of their composite materials. Stable isotopes remain the same over time while the nucleus of an unstable or radioactive isotope will decay to form other isotopes
.
Dating rocks using Isotopic methods uses the decay time of the isotope in the rock to assess its age. The accuracy of this method is assured by the fact that when these isotopes decay, they are retained in the rock. Isotopic dating is not very accurate in sedimentary rocks because they contain particles from older rocks.
