Disadvantages of Choropleth Maps
Although choropleths give a good visual impression of change over space there are certain disadvantages to using them:
They give a false impression of abrupt change at the boundaries of shaded units.
Choropleths are often not suitable for showing total values. Proportional symbols overlays (included on the choropleth map above) are one solution to this problem.
It can be difficult to distinguish between different shades.
Variations within map units are hidden, and for this reason smaller units are better than large ones.
Isopleth maps
Isopleth maps differ from choropleth maps in that the data is not grouped to a pre-defined unit like a city district. These maps can take two forms:
Lines of equal value are drawn such that all values on one side are higher than the "isoline" value and all values on the other side are lower, or
Ranges of similar value are filled with similar colours or patterns.
This type of map is ideal for showing gradual change over space and avoids the abrupt changes which boundary lines produce on choropleth maps. Temperature, for example, is a phenomenon that should be mapped using isoplething, since temperature exists at every point (is continuous), yet does not change abruptly at any point (like population density may do as you cross into another census zone). Relief maps should always be in isopleth form for this reason.

External contact and intercultural exchange benefitted early civilizations. This is true of both the civilizations of sub-Saharan Africa and those of Southeast Asia.
In the case of Sub-Saharan Africa, one such civilization was that of the Kingdom of Kush. This was established around 1070 BCE. Kush developed in a region known as Nubia, in the Sudanese and southern Egyptian Nile Valley. Much of the success of the Kingdom of Kush came from its interactions with Egypt. Kush was an important producer of gold and ivory, and by trading with Egypt, it achieved great wealth. It also acquired some of the traditions of Egypt, such as the building of pyramids and mummification.
Southeast Asian civilizations also benefitted from trade in their early years, particularly maritime trade. The Austronesian people built the first ocean-going ships. They trade with areas such as Southern India and Sri Lanka. This also connected these people with the cultures of India and China. This trade led to a rise in technological knowledge and traditions. Some of the items that were exchanged in this trade were catamarans, outrigger boats, sewn-plank boats, coconuts, sandalwood, bananas, and sugarcane.
