Select ALL correct statements about the Earth and its orientation.
Answer
Earth's orbit around the Sun is elliptical, Earth's seasons are caused primarily by axial inclination, The geographic poles are where Earth's rotational axis meets its surface
Explanation
Earth follows an elliptical orbit, but seasonal changes are primarily caused by the inclination of its rotational axis relative to the ecliptic. The rotational axis meets Earth's surface at the geographic poles, not the magnetic poles. **Key takeaway:** Geographic and magnetic poles are distinct, and axial tilt drives seasons.\n\n**Glossary:** **Ecliptic**: the plane of Earth's orbit around the Sun; **axial inclination**: the tilt of Earth's rotational axis.
