Question

background information: by now, you should have a better understanding of what causes seasons on the earth. obviously, some regions of earth do not experience four individual seasons. this activity is designed to expand and extend this information and apply it to our earth and other planets in a unique way using four seasons as a base - study. part i: observe earths tilt and each season that occurs as a result for the northern hemisphere. using the diagram below, answer the questions. 1. when the northern hemisphere is experiencing summer, what season is the southern hemisphere experiencing? 2. when the northern hemisphere is experiencing spring, what season is the southern hemisphere experiencing? 3. will the northern hemisphere and southern hemisphere ever experience the same season? why? 4. does the tilt of earths axis ever change the direction while revolving around the sun? 5. what star does the north pole point towards all year (hint: provide the name of the current north star)?

Explanation:

1. The Earth's tilt causes opposite seasons in the Northern and Southern Hemispheres. When the Northern Hemisphere has summer, the Southern Hemisphere has winter as it is tilted away from the Sun.
2. When the Northern Hemisphere has spring, the Southern Hemisphere has autumn as the Earth's position in its orbit means different hemispheres receive different amounts of sunlight.
3. No, they will not experience the same seasons at the same time because of the Earth's axial tilt. One hemisphere is always tilted more towards or away from the Sun than the other.
4. No, the tilt of Earth's axis remains relatively constant in direction as it revolves around the Sun, which is why we have consistent seasonal patterns.
5. The North Pole points towards Polaris (the North Star) all year.

Answer:

1. Winter
2. Autumn
3. No, because of Earth's axial tilt.
4. No, it remains relatively constant.
5. Polaris
