Answer:
Explanation:
Water surplus exists where supply exceeds demand. These are known as WATER SURPLUS areas. These are located in temperate and tropical wet areas with high rainfall and lower populations. Areas include the Amazon Basin, large parts of North America and Western Europe.
Areas with a water deficit or water shortage include Northern Africa and the Middle East where there may be low levels of rainfall, high agricultural demands and/or high population densities.
A cyclic change in the earth system repeats the same steps over and over, though not necessarily with the same results or at the same rate.
The Earth's climate cycles across a wide range of time scales, from years to decades to centuries to millennia. Different physical processes can start cycles at different scales. All of these layered systems and cycles working in concert determine the climate over any particular period.
Scientists examine Earth's cycles in an effort to understand how our world functions. Our planet's climates can vary as a result of modifications to Earth's cycles. Our understanding of how humans are influencing these cycles and how that can transform the world will grow as we learn more about them.

The explanation is that the two continents must have been once connect to form a super continent called Pangaea. The fossil was part of a herd that probably crossed Pangaea. When Pangaea split animals were on both sides. That is why fossils found in South America are found in Africa.
Explanation:
The dry regions or deserts found in and about 30° north and south of the equator are called the subtropical deserts. They are predominantly found in between 15° to 30° north and south of the equator where it is called the Tropic of Cancer in the north and Tropic of capricorn in the south of the equator. In these regions the air masses travels in the circular patterns, which is the main cause of hot and dryness in these regions.
Near the equator the hot air rises and as it raises it cools down and drops its moisture in the form of rain near the equator. Thus now the drier air moves away from the equator towards the Tropics of cancer and the tropic of capricorn and thus it descends down and becomes hot again. As the air lowers down it becomes difficult to form cloud and thus there is little rainfall in these area making it hot and dry. Thus they formed subtropical deserts.
