1.1.2  Which of the following is true about the Earth’s axis, the Earth’s revolution around the Sun, and the seasons? 

• Changes in the direction of the Earth’s axis cause the seasons 
• The Earth’s axis keeps pointing in the same direction, and as Earth travels around the Sun, the angle between the axis and the Sun changes, causing the seasons.
