Six friends were talking. They each had different ideas about why it is warmer in the summer than in the winter. This is what th
ey said: Which friend do you most agree with?
*
Werner: “It’s because the winter clouds block heat from the Sun.”
Ava: “It’s because the Sun gives off more heat in the summer than in winter.”
Raul: “It’s because Earth’s tilt changes the angle of sunlight hitting Earth.”
Fernando: “It’s because the Earth orbits closer to the Sun in the summer than in the winter.”
Shakira: “It’s because one side of Earth faces the Sun and the other side faces away.”
Susan: “It’s because the Northern Hemisphere is closer to the Sun in summer than in the winter.”
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
