Back

The axis is an imaginary line that runs from the North Pole to the South Pole, around which the Earth rotates.

Front

Why does the Earth tilt on its axis?

Back

The Earth tilts on its axis at an angle of about 23.5 degrees, which affects the seasons and the amount of sunlight different parts of the Earth receive.

Front

What is the period of rotation for the Earth?

Back

The period of rotation for the Earth is approximately 24 hours.

Front

What is the effect of the Earth's revolution around the Sun?

Back

The Earth's revolution around the Sun causes the changing of the seasons throughout the year.

Front

What is a globe?

Back

A globe is a three-dimensional representation of the Earth that shows continents, oceans, and the tilt of the Earth's axis.

Front

What are the four seasons?

Back

The four seasons are spring, summer, autumn (fall), and winter, which result from the tilt of the Earth's axis and its revolution around the Sun.

Front

What is the equator?

Back

The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres, located equidistant from the poles.
