Question

What is one cause of long-lasting climate change?

glacial deposits
Earth’s elliptical orbit
Earth’s rotation
the Sun’s elliptical orbit

Answer 1

Earth’s elliptical orbit. Changes in the shape (eccentricity) and orientation of Earth’s orbit and tilt (Milankovitch cycles) alter how much solar energy different latitudes receive over tens of thousands of years, driving long-term climate changes such as ice ages.
