Earth's Rotation and Revolution

Front

What is Earth's rotation?

Back

Earth's rotation is the spinning of Earth on its axis, which takes approximately 24 hours to complete one full turn, resulting in day and night.

Front

What is Earth's revolution?

Back

Earth's revolution is the movement of Earth around the Sun in an elliptical orbit, taking about 365.25 days to complete one full orbit, which defines a year.

Front

What causes the seasons on Earth?

Back

The tilt of Earth's axis and its revolution around the Sun cause the seasons. As Earth orbits, different parts receive varying amounts of sunlight.

Front

What is the polar front jet stream?

Back

The polar front jet stream is a fast-flowing air current in the atmosphere that influences weather patterns and varies in position with the seasons.

Front

What is perihelion?

Back

Perihelion is the point in Earth's orbit where it is closest to the Sun.

Front

What is aphelion?

Back

Aphelion is the point in Earth's orbit where it is farthest from the Sun.

Front

How does the Sun's vertical rays affect seasons?

Back

The vertical rays of the Sun shift north and south with the seasons, affecting the intensity and duration of sunlight received at different latitudes.

Front

What is the significance of the Tropic of Capricorn?

Back

The Tropic of Capricorn is the southernmost latitude where the Sun can be directly overhead at noon, occurring during the December solstice.

Front

What is a Foucault pendulum?

Back

A Foucault pendulum is a device that demonstrates Earth's rotation by swinging in a constant direction while the Earth rotates beneath it.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the apparent deflection of moving objects (like air currents) caused by Earth's rotation, influencing weather patterns.
