Hey there! Darwin's finches had different beak sizes and shapes because of natural selection. Over time, the more desirable traits become more dominant and distinct. These beaks were best fit for the type of food the bird ate. Smaller-beaked birds usually have a seed diet, and larger-beaked birds usually eat large nuts or small creatures like worms and bugs. Hope this helps!
Oceans bring warm water to distant shores. Ocean temperatures and winds are coupled into a complex interactive system. Varying ocean temperatures affect local atmospheric pressure, which creates regional wind patterns that, in turn, drive oceanic currents that affect surface ocean temperatures.
