Seasons, Ocean Circulation, El Niño & La Niña

The primary cause of Earth's seasons is the. . .

• Tilt of Earth's rotational axis with respect to its orbit around the sun

• Changing distance of Earth from the sun at different times of year

• Periodic wobbling of Earth on its axis of rotation

• Periodic changes in solar energy output from the sun
