Answer:
Continental drifting
Explanation:
Continental drifting talks about the movement of continents . The process was first discovered by Alfred Wegener. Alfred Wegener noticed the great similarities of the Atlantic coastline of Africa and the south America. He noticed the edge of each continents fits like a puzzle. The idea that the continents were once joined together and have split apart was born out of the observation of the similarities of the continents.
The similarities of fossil found in different continents also proved that the continental has been drifting . The similar fossils found in different continents were better explained if the continents were once joined together. Fossils like the Mesosaurus , a fresh water reptile were found in different continents.
The similarities in rock structure also proved the continents have been drifting .
<span>The correct answer is : C.
Botswana.</span>
Botswana is a topographically flat country wherein 70
percent of its territory is the Kalahari Desert. Because Botswana is bordered
by South Africa to the south and southeast area of its territory and by Namibia
to the west and north territory, minimal land areas of both countries are included
in the 900,000 square kilometer land area of Kalahari Desert.
Kalahari Desert also encroached on some parts of Zambia but
no part of Mozambique.
Answer:
The difference between levels of high tide and low tide
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.
