PEOPLE!!



The population in America varies according to the conditions of life. In Latin America, most of their inhabitants are young of age between the 15 and 24 years, and the life expectancy varies between the 60 and 80 years of age. In addition, more than half of the population in the majority of the countries he is rural. A special case is the one of Argentina, Chile, Cuba and Uruguay, since these countries have a demographic structure similar to the European, because most of their inhabitants are adult and surpass the youthful population. In countries like Bolivia, Haiti, El Salvador, Honduras, Nicaragua, Panama, Puerto Rico and Dominican Republic, exist a greater youthful population, predominating the young people between the 15 and 25 years of age. Finally, in countries like Brazil, Colombia, Ecuador, Guatemala, Costa Rica, Mexico, Paraguay, Peru and Venezuela, also most of their inhabitants are young, although in the last decades it has also undergone a great adult growth and a progressive aging similar to Asian Europe and some countries although to a lesser extent. The same happens in the ultramarine departments of Guadalupe, Guayana Francesa and Martinique (pertaining to France) and in nonLatin countries like Bahamas, Belize, Guyana, Jamaica, Surinam, the Small Antilles, Trinidad and Tobago, including the European dependencies like the Dutch Antilles, Aruba, etc. In North America, on the contrary, most of their inhabitants are adult, surpassing the youthful population, as it happens with the European population, because in this region also a progressive aging of the population has taken place. Thus it happens in countries like Canada, the United States and the European dependencies like Greenland (pertaining to Denmark) and San Pedro and Miquelón (pertaining to France), although in the United States this tendency has been reduced due to Latin immigration, mainly young. The unique exceptions are Mexico and the Bermuda islands (pertaining to the United Kingdom), of mainly youthful population.

CLIMATE!!


Generally the climate is wet and tropical. Summer is the principal rainy season although there is no specific dry season. The eastern Caribbean and Pacific coastal lowlands experience an equatorial climate with high temperatures and high humidity all year round, with rainfall averaging 40 inches (1,000mm) a year. In the mountainous parts conditions are cooler and can be changeable depending on prevailing winds, altitude and topography.

The Climate of Colombia is characterized for being tropical and isothermal as a result of its geographical location near the Equator presenting variations within five natural regions and depending on the altitude, temperature, humidity, winds and rainfall. Each region maintains an average temperature through out the year only presenting variables determined by precipitations during a rainy season caused by the Intertropical Convergence Zone.

The geographical factors are determined by latitude or altitude. Colombia is crossed by the equator in its southern part, but the majority of the territory is part of the northern hemisphere and within the torrid zone which is characterized for receiving direct sunlight throughout the year. A considerable area of Colombia is mountainous, mainly crossed by the Andes mountain range from south to north. Altitude in this mountains counter rest the effects of the latitude characteristics producing gradual variable climates from tropical foothills and coastlines to perpetual snow peaks.

The atmospheric factors are determined by temperature, humidity and winds. The temperature is relatively average throughout the year in a same place. The tropical location of Colombia and the uniform solar radiation for being in the equator gives this country an almost constant temperature. The atmosphere varies due to the altitude in the mountains and its proximity to sea level.
