Earth and Sun Review

The image shows a tree and its shadow.

Which statement best estimates the time of day and explains what is seen in the image?

• It is sunrise. As the Earth turns on its axis, the Sun rises in the east. When the Sun is low in the sky, there are long shadows to the east.

• It is late morning. The Sun revolves around Earth each day, so Earth casts long shadows in the late morning to the east.

• It is late afternoon. The Sun is getting lower in the western sky casting a long shadow to the east.

• It is just after sunset. The Sun sets in the west and the tree blocks light from the Sun, making the longest shadow of the day to the east.

We are closer to the Sun during the day, so it is visible, but at night we are closer to the stars so they are visible.
