Globe Observer

Which of these cycles is a direct result of Earth's rotation?

• Day and Night

• Moon Phases

• Rainfall and evaporation

• Seasons

Some students use globes to model the rotation of the Earth. They shaded in Texas on the globe, as shown. They rotated the globe and observed that Texas was in exactly the same place after each rotation. The students could rotate the globe quickly or slowly. If the globe could rotate only at the rate that Earth actually rotates, about how long would each complete rotation take?

• 30 days

• 60 minutes

• 24 hours

• 365 days

A student draws a model showing the movements on Earth, the moon, and the sun. Which arrow shows the movement that caused day and night on Earth?

• Arrow 1, because it shows the rotation of the sun

• Arrow 2, because it shows the orbit of Earth around the sun

• Arrow 3, because it shows the orbit of the moon around Earth

• Arrow 4, because it shows the rotation of the Earth

The accompanying diagram shows the apparent path of a projectile fired from Earth's North Pole toward a target located at 45 degrees North Latitude. The apparent curving of the projectile's path, as seen by observers on Earth, is caused mainly by

• prevailing winds

• convection currents

• Earth's rotation

• gravitational forces
