Migration is called, any movement of the population (human or animal) that occurs from a place of origin to another destination and bringsa change of habitual residence in the case of individuals or habitat for animal speciesmigratory.

Physical Geography

Europe, the second smallest continent in the world after Pacific, has an area of ​​10,530,751 km ², representing 7% of land area.
Characterizes Europe, both geographically (as much climate impact as its human geography), the high average amount of coastline and ocean due to the presence ofnumerous peninsulas, bays, inland seas and islands. This and the influence of the Gulf Stream and the proximity of the hot deserts of Africa and Asia than in Europe determine preponderates, despite latitudes, an exceptionally mild temperate climate for human habitation.
Europe also, if considered in the traditional way as a continent, the flattest continent, with an average height of 230 meters.

Population density

The population density in Spain is 79 inhabitants per kilometer cuadrado.En 1900 the population density was 38 people per km cuadrado.The density lets us know the number of inhabitants per square kilometer and we see that in the past years, the population density has increased.
In Spain we approximately thirty-nine million people. The number of inhabitants of a territory is their absolute population. Compared to European Union countries, Spain has fewer inhabitants than Germany, France, Italy and the United Kingdom,and Finland, Greece or Ireland.

Model of population cycle

A population cycle in zoology is a phenomenon where populations rise and fall over a predictable period of time. There are some species where population numbers have reasonably predictable patterns of change although the full reasons for population cycles is one of the major unsolved ecological problems. There are a number of factors which influence population change such as availability of food, predators, diseases and climate.

The water cycle is a constant interaction with the ecosystem because living things depend on this element to survive and in turn help the operation.
1 º evaporation. Water evaporates at the ocean surface on Earth's surface and also by agencies in the phenomenon of transpiration in plants and animals sweating.
2 º condensation. The water vapor rises and condenses into clouds, formed by water droplets.
3 º Precipitation. It occurs when water droplets form clouds cool accelerating.
4 º Infiltration. Occurs when the water reaches the ground, penetrates the pores and becomes groundwater.
5 º Runoff. This term refers to the various means by which liquid water slides downhill on the surface of the ground.
6 º Circulation groundwater. Occurs for gravity, as surface runoff, which can be considered a version.
