Answer:
•The existence of water at the Earth’s surface—neither too much nor too little—that is in liquid form.
•Proximity to the sun—neither too much heat nor too little.
•System of plate tectonics that enables the carbon-silicate cycle regulating temperature.
•The right size—large enough to hang on to its atmosphere, but not so large to hold on to too much atmosphere and consequently too much heat.
•Its protection by “big brother Jupiter,” whose gravity helps divert and vacuum up incoming debris and keep Earth safe.
•The moon’s stabilizing effect on our planetary rotation, which prevents the poles from shifting unexpectedly.

Explanation:
Climate change is a highly contentious topic in the modern world. There is much evidence to indicate that climatic shifts and extreme weather anomalies are taking place globally, in some places more than others. This paper presents the findings on research to determine whether shifts in seasonal rainfall patterns are indeed already visible in historical rainfall data in the Western Cape of South Africa. The paper aims to provide some baseline information which can stimulate further research in this field. Different analytical methods were formulated to investigate the relationships between daily rainfall indices over a set timescale. Data was collected from the South African Weather Service (SAWS) in order to accumulate 20 rainfall stations, each with at least 100 years of historical daily rainfall data. Statistical analysis, linear trend line distributions, time lag comparisons, cumulative distributions, moving average plots and autocorrelation relationships were applied to the data. The results of the analysis indicated that (1) the rainfall season undergoes fluctuations of wetter and drier years (approximately 20-year cycles), (2) the South Coast region exhibits a shift towards a longer rainfall season, and in contrast the Mediterranean region is shifting to a shorter rainfall season when linear trend lines were analysed, and (3) the moving average plots showed only isolated seasonal shifts at the boundary months.

Answer:
According to researches, the Native population in Americas before the arrival of Europeans was around 100 million people, while some are estimating that it was even more.
Explanation:
Before Europeans arrived in America, many native culture were developing and some were even at their peak.
But when the conquistadores came, they killed a lot of them, while a lot of them died due to diseases that were brought by Europeans.
The population in just a couple of decades fell from 100 millions to just a couple of millions.
