The answer is D because the lithosphere is the crust of earth and the hydrosphere is the water on the earth.
The Singapore we know today has a history marked by rapid transformations. Created initially by British political and economic interests, it was the local and world economic changes that proved to be the great spring of transformation of the country and its society.
A Brief Chronology
2nd century. First records of Singapore.14th century. Origins of the name of Singapore, Singapore or "City of the Lion".1819. Sultanate of Johor allows the installation of a British commercial warehouse on the island.Second World War. Japanese invade the British colony.1955. Self-government for Singapore.1958. Birth of the State of Singapore.1963. Singapore integrates Malaya into Malaysia.1965. Singapore is no longer part of Malaysia. The Republic of Singapore is born.The Primors
The earliest records about Singapore are from the second century where it appears on a map created by the mathematician, astrologer and geographer Ptolemy. In the third century there are Chinese accounts in which it is termed "Island at the End", a reference to its location at the extreme end of the Malay Peninsula.
The name Singapore had its origin in the 14th century, when the Prince of Srivijaya when visiting the region would have seen a lion (something very unlikely for the region, which was inhabited by tigers and not lions). After this supposed encounter, the region happened to gain the name of Singapore, that in Sanskrit means City of the Lion (singa = lion and pure = city).
An open lake is a lake where water constantly flows out under almost all climatic circumstances. Because water does not remain in an open lake for any length of time, open lakes are usually fresh water: dissolved solids do not accumulate. Open lakes form in areas where precipitation is greater than evaporation. Because most of the world's water is found in areas of highly effective rainfall, most lakes are open lakes whose water eventually reaches the sea. For instance, the Great Lakes' water flows into the St. Lawrence River and eventually the Atlantic Ocean.
In a closed lake (see endorheic drainage), no water flows out, and water which is not evaporated will remain in a closed lake indefinitely. This means that closed lakes are usually saline, though this salinity varies greatly from around three parts per thousand for most of the Caspian Sea to as much as 400 parts per thousand for the Dead Sea. Only the less salty closed lakes are able to sustain life, and it is completely different from that in rivers or freshwater open lakes. Closed lakes typically form in areas where evaporation is greater than rainfall, although most closed lakes actually obtain their water from a region with much higher precipitation than the area around the lake itself, which is often a depression of some sort.
