Answer 1

B) River valeys.
the earliest civilizations in history, such as Mesopotamia, Egypt, China, and India, were found near rivers because, when rivers flooded, people could grow more food for themselves and for trade. This system, the basis of all these early civilizations, is called the "river-valley civilizations".
THe four river-valley civilizations of India, China, Egypt, and Mesopotamia were among the earliest civilizations in history.

The Indus Valley Civilization (c. 3300–1300 BCE, flowered 2600–1900 BCE) was an ancient civilization thriving along the Indus River and the Ghaggar-Hakra River in what is now Pakistan and north-western India. Among other names for this civilization is the Harappan Civilization, in reference to its first excavated city of Harappa. The Indus Valley Civilization (IVC) was discovered in the 1920s and is known only from archaeological excavations, except, possibly, for Sumerian references to Meluhha, which has been proposed to correspond to the IVC.

The history of China is detailed by historical records dating as far back as 16th century BC. China is one of the world's oldest continuous civilizations. Turtle shells with markings reminiscent of ancient Chinese writing from the Shang Dynasty (商朝) have been carbon dated to around 1500 BC. These records suggest that the origins of Chinese civilization started with city-states in the Yellow River valley.

Mesopotamia refers to the region now occupied by modern Iraq, eastern Syria, and southern Turkey. The name comes from the Greek words μέσος "between" and ποταμός "river", referring to the area between the Euphrates and the Tigris (the Arabic term is بين نهرين Bayn Nahrain "between two rivers"). The fertile area watered by these two rivers is known as the "Cradle of Civilization," and it was here that the first literate societies developed.

Ancient Egypt was a long-lived ancient civilization geographically located in north-eastern Africa. It was concentrated along the middle to lower reaches of the Nile River reaching its greatest extension during the second millennium BC, which is referred to as the New Kingdom period. It reached broadly from the Nile Delta in the north, as far south as Jebel Barkal at the Fourth Cataract of the Nile. Extensions to the geographical range of ancient Egyptian civilisation included, at different times, areas of the southern Levant, the Eastern Desert and the Red Sea coastline, the Sinai Peninsula and the Western Desert (focused on the several oases).

Ancient Egypt developed over at least three and a half millennia. It began with the incipient unification of Nile Valley polities around 3500 BC and is conventionally thought to have ended in 30 BC when the early Roman Empire conquered and absorbed Ptolemaic Egypt as a province. (Though this last did not represent the first period of foreign domination, the Roman period was to witness a marked, if gradual transformation in the political and religious life of the Nile Valley, effectively marking the termination of independent civilisational development).

Answer 2

"im.in" is right about mountains and the Arctic. But deserts do exist on the coast -- the Sahara, California, Namibia, Somalia for examples. The sea supports life in the sea, but not on land unless winds blow off the sea and create rain.

Rivers are helpful for agriculture and if deep enough for transport so before the industrial age most people had to live near rivers.

Nowadys people can build cities anywhere and bring food and water from somewhere else. Las Vegas, Los Angeles and Dubai are examples of cities that have got much bigger in the past 50 years because people do not nowadays need to have local sources of food and water.

Answer 3

River valleys. Remember the Nile River basin? The silt helped the Egyptians, Mesopotamians, and others to grow crops and it provided transportation, drinking water, and a whole lot of other stuff too.

Coastline with deserts cannot exist: deserts lack water and coastlines are full of water. Arctic conditions cannot sustain human life. Mountains are a severe hindrance to population density since they cannot support large populations.

Answer 4

All of us know very well that all the ancient civilizations started in the river valleys namely:-
Indus Valley civ along the Indus river,
Mesopotamian civ along the Tigris & Euphrates rivers,
Egyptian Civ along the Nile river, etc, etc...
So clearly the rivers provode the basic need of the humans (then) the water.

Although now a days the population is attracted towards the employment/ Job prospects i.e. the big cities, the cities which r already big, r growing faster therefore.

Answer 5

river valleys.
