Historical Influence on Biodiversity: Plate Tectonics & Climate

When we look at the biodiversity of life today it is vital we look at it through the eyes of history - what historical influences have led to life on Earth as we know it today?

The movement of continents and the effect this has had on climate is obviously a big one.

The movement of continents has been vital for the evolution of biodiversity because:

• It facilitated the spread and separation of animals and plants around the globe.
• Changes the albedo and thermal properties of land and sea, in turn affecting climate.
• Creates and breaks super continents: Which influences albedo, currents, winds, rainfall and consequently climate.
• Creates volcanoes: Which influences CO2 levels of the atmosphere.
• Mountain formation: Influence on rainfall and moisture of surrounding regions.  It also creates a whole new biome.
