Pre Test Interaction of the Sun, Earth, Moon

Front

What force keeps the planets orbiting the sun, the moons orbiting the planets, and you on the surface of the Earth?

Back

Gravity is the force that keeps planets in orbit around the sun, moons around planets, and objects on the surface of the Earth.

Front

What would happen to the planets of our solar system without the sun's gravity?

Back

Without the sun's gravity, the planets would be flung out into space in a straight line.

Front

What is the apparent movement of the Sun across the sky during the day due to Earth's rotation?

Back

The apparent movement of the Sun from east to west across the sky is due to Earth's rotation.

Front

Why does Earth experience seasons?

Back

Earth experiences seasons because its axis is tilted about 23 degrees, affecting the amount of direct solar energy received.

Front

What happens when the north end of Earth’s axis is tilted toward the sun?

Back

When the north end of Earth’s axis is tilted toward the sun, North America experiences more direct solar energy, longer days, and a summer season.

Front

How long does it take for the moon to make one full orbit around Earth?

Back

The moon takes about 30 days to make one full orbit (revolution) around Earth.

Front

What is the role of gravity in the solar system?

Back

Gravity is the fundamental force that governs the motion of celestial bodies, keeping them in their orbits.

Front

What is the significance of the Earth's axial tilt?

Back

The Earth's axial tilt is significant because it causes variations in solar energy received at different latitudes, leading to seasonal changes.

Front

How does the rotation of the Earth affect our perception of the Sun's movement?

Back

The rotation of the Earth creates the illusion that the Sun moves across the sky, when in fact it is the Earth that is rotating.

Front

What would happen to Earth if it were not tilted on its axis?

Back

If Earth were not tilted on its axis, there would be little to no seasonal variation in climate.
