What direction does Earth rotate and revolve?

• clockwise

• counterclockwise

Why do globes lean sideways?

• To allow them to spin easier.

• To demonstrate the tilt of Earth's axis.

• To demonstrate the effects of gravity.

• To demonstrate day and night.

Imagine there was no tilt to the Earth's axis and Earth's orbit was circular. What would be true about the length of days and nights on Earth?

• The periods of day and night would be fixed all year, for any location.

• Night, as we know it on Earth, would end. We would be in constant daylight.

• The periods of day and night would be fixed all year for anyone living at Earth's equator.

• The areas closest to the equator would have constant daylight during the year; the areas near the poles, constant night.

A fourth-grader in Florida is doing an experiment in her science class. At the same time, a fourth-grader in India is getting a good night's sleep. What is responsible for it being daytime in Florida while it is nighttime in India?

• The Earth's orbit around the Sun

• The Moon's orbit around the Earth

• The Earth's rotation

• The Sun's rotation

Answer explanation

It is the daily spin, or rotation, of the Earth that makes each location pass through periods of light and shadown, or day and night.
