Final answer:
The Earth's tilt is thought to have caused the ice ages by affecting the amount of sunlight received by different areas of the Earth.
Step-by-step explanation:
The Earth's tilt is thought to have caused the ice ages. The tilt of the Earth's axis causes changes in the amount of sunlight received by different areas of the Earth throughout the year. When the tilt is more extreme, the amount of solar radiation reaching the poles decreases, leading to colder temperatures and the formation of ice sheets. Conversely, when the tilt is less extreme, more solar radiation reaches the poles, causing the ice to melt.
