First Law of Thermodynamics - Energy is neither created nor destroyed, but may be converted from one form to another. El Niño (ENSO) - prevailing winds in the Pacific weaken and change direction every few years which results in above average warming of eastern Pacific waters, which changes distribution of plant nutrients and alters earth's weather for 2-3 years Reason for seasons on Earth - Tilt of the axis ~23.5° Second Law of Thermodynamics - When energy is changed from one form to an...
