What is an example of isolation?
The Great Lakes is an example of a geographic barrier, isolating populations from each other. Populations can become separated (isolated) from one another, as one group expands northward of the lakes and another expands southward of the lakes. Mountain ranges are geographic barriers that isolate populations from one another, in much the same way as the great lakes. Oceans geographically isolate land masses, and their respective populations, from one another. This includes islands as well as continents. Examples: the Galapagos Islands, Madagascar, and Australia. *Geographic isolation is the chief mechanism of allopatric speciation, considered by some to be a theory.

How did Venice get flooded?
Venice is located in the northern part of the Adriatic Sea just off the coast of Italy. This part of the sea is generally a calm area but during storms the waves crash onto the main land of Venice causing floods. The storms haven't always had this effect on Venice. Before the island off the coast were able to hold back the storm water and keep Venice from flooding. Lately however, the Adriatic Sea has risen and the islands can no longer keep the water from entering Venice causing the floods. Also, when the floods come in, the soil under Venice become very swampy causing the city to sink into the ground a slight bit making it more susceptible to flooding.
