3.2 Origins of biodiversity
Parts of Earth's interior
Thin crust on the outside
A core of significant size in the center
Most of the mass of the Earth contained in the Mantle
Continental drift
Transformation
Crust not made or destroyed
E.g. San Andreas fault line, California
Diverging
Crust made
E.g. Mid Atlantic ridge
Converging
Crust destroyed
E.g. Himalayas forming mountains
Creates new land bridges and niches
Evolution
The change in a population's genetic makeup through successive generations
Isolation
can lead to different species being produced, which are unable to interbreed to yield fertile offspring
