Wyatt slowly spins the globe. He notes that at this time of year, Morocco would have longer days and

shorter nights. What should Wyatt do to model the time of year when Morocco has shorter days and longer

nights?

• Wyatt should spin the globe faster.

• Wyatt should move the flashlight closer to the globe.

• Wyatt should change the direction that the globe is spinning.

• Wyatt should move the flashlight to the other side of the globe.

Why is his model is incorrect?

• Earth does not tilt on its axis.

• Earth does not rotate on its axis.

• The Sun does not shine on Earth from that angle.

• The Sun does not shine on only one side of Earth at a time.

Using the model, what would

most likely

happen if Earth were not tilted on its axis?

• Earth would take much longer to revolve around the Sun.

• The lengths of day and night on Earth would always be equal.

• The Sun would shine more directly on the Northern Hemisphere.

• One side of Earth would always be dark and the other always light.

Which letter shows the location where the Northern Hemisphere has the longest days and shortest nights?

• W because Earth is at its closest distance from the Sun during its elliptical orbit

• X because the Southern Hemisphere has direct sunlight for a longer time period

• Y because Earth is at its farthest distance from the Sun during its elliptical orbit

• Z because the Northern Hemisphere has direct sunlight for a longer time period

The length of daytime changes during the year. Why does this happen?

• because the Sun tilts on its axis and moves around Earth

• because Earth spins on its axis and moves around the Sun

• because Earth spins on its axis and moves around the Moon

• because the Sun tilts on its axis and moves around the Moon

Aaliyah would like to demonstrate why the length of day and night change throughout the year. She has a

globe and a flashlight. Which two factors are most important for Aaliyah to use in her model?

• The tilt of Earth on its axis and Earth's orbit around the Sun.

• The direction of Earth's rotation and the speed of Earth's rotation.

• The speed of Earth's rotation and the distance of Earth from the Sun.

• The distance of Earth from the Sun and Earth's orbit around the Sun.

How long does it take Earth to make one full rotation on its axis?

• 24 Hours

• 1 Week

• 1 Month

• 365 Days

What causes day and night on Earth?

• the revolution of the Sun

• the revolution of Earth around the Sun

• the rotation of the Moon around Earth

• the rotation of Earth on its axis

Why don't all parts of Earth have day and night at the same time?

• The Sun revolves around Earth, and it can only shine on half of Earth at one time.

• Earth rotates on its axis, and only the part of Earth facing the Sun experiences day.

• The Moon revolves around Earth, and it blocks the Sun from certain parts of Earth at different times.

• Earth revolves around the Sun on an axis, and it is day only when that part of Earth is tilted toward the Sun.
