The moon takes approximately 27.3 days to complete one orbit around the Earth.

Front

What is the reason we see different phases of the moon?

Back

The phases of the moon are caused by the changing angles of sunlight hitting the moon as it orbits Earth.

Front

What is a solar eclipse?

Front

What causes the seasons on Earth?

Back

Seasons are caused by the tilt of Earth's axis as it revolves around the Sun, affecting the angle and intensity of sunlight received.

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.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of Earth on its axis, taking about 24 hours, while revolution is the orbit of Earth around the Sun, taking about 365.25 days.

Front

What is the significance of the North Star?

Back

The North Star, or Polaris, is significant because it is located nearly directly above the North Pole and is used for navigation.

Front

What is the tilt of Earth's axis?

Back

Earth's axis is tilted at an angle of approximately 23.5 degrees, which is responsible for the changing seasons.
