Objective – Explain that Earth's axis is tilted relative to its yearly orbit around the Sun.
1. Describe what occurs during Sunset and Sunrise. You must use the unit vocabulary as part of your answer. Underline vocabulary words. Use complete sentences.
During sunset and sunrise the Earth is rotating on its axis. The Sun appears to be moving through the sky when it is actually the Earth rotating.
2. What is the Earth’s axis? Use complete sentences.
An imaginary line going from the North Pole to the South Pole. The earth spins on this line.
3. Using the terms revolves, axis, tilt, Sun, and angled, describe why the different seasons occur.
Underline the terms you are required to use.
The Earth tilts on its axis 23.5
o . As the Earth revolves around the Sun, different parts of the Earth tilt towards or away from the Sun. When the axis tilts towards the Sun, that hemisphere experiences summer. When the axis tilts away from the Sun, that hemisphere experiences winter. When the Earth neither tilts towards nor away from the Sun, that hemisphere experiences fall or spring.

4. This graph shows the daylight hours throughout the year for an unknown city. Is the unknown city in the Northern or Southern Hemisphere?
Southern Hemisphere
Explain why you chose the Northern or Southern Hemisphere, using the data on the graph as a part of your explanation. Use complete sentences.
The key piece of data is the daylight hours during Jun, July, and August. In the
Northern Hemisphere, these months would be summer. We receive the most daylight hours in summer. We receive the fewest daylight hour during the winter. This city experiences winter during June, July, and August, therefore, it must be in the Southern
Hemisphere.
