Front

What causes the seasons on Earth?

Back

The seasons are caused by Earth's tilt on its axis and its orbit around the sun.

Front

What is the significance of the Autumnal and Vernal Equinoxes?

Back

During the Autumnal and Vernal Equinoxes, day and night are approximately equal in length.

Front

What is a high tide?

Back

A high tide is the point at which the water level is at its highest due to the gravitational pull of the moon and sun.

Front

What is a low tide?

Back

A low tide is the point at which the water level is at its lowest.

Front

How long does it typically take for a tide to change from high to low?

Back

Front

What season occurs when the Northern Hemisphere is tilted towards the sun?

Back

Summer occurs when the Northern Hemisphere is tilted towards the sun.

Front

What season occurs when the Northern Hemisphere is tilted away from the sun?

Back

Winter occurs when the Northern Hemisphere is tilted away from the sun.

Front

What is the role of Earth's rotation in tides?

Back

Earth's rotation affects the timing of tides, causing them to rise and fall approximately every 6 hours.

Front

What is the difference between spring tides and neap tides?

Back

Spring tides occur during full and new moons when the tidal range is greatest, while neap tides occur during the first and third quarters of the moon when the tidal range is smallest.

Front

What is the tilt of Earth's axis?

Back

Earth's axis is tilted at an angle of approximately 23.5 degrees.
