Cause of Seasons and Tides Flashcard

Front

What causes the seasons on Earth?

Back

The tilt of Earth's axis and its orbit around the sun cause the seasons.

Front

What is the tilt of Earth's axis?

Back

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

Front

What happens during winter in a hemisphere?

Back

The hemisphere is tilted away from the sun, resulting in shorter days and cooler temperatures.

Front

What is a tide?

Back

A tide is the rise and fall of sea levels caused by the gravitational forces exerted by the moon and the sun.

Front

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides.

Front

What is the difference between spring and neap tides?

Back

Spring tides occur when the sun, moon, and Earth are aligned, resulting in higher high tides and lower low tides. Neap tides occur when the sun and moon are at right angles to each other, resulting in lower high tides and higher low tides.

Front

What is the role of gravity in tides?

Back

Gravity pulls water towards the moon and the sun, causing the water level to rise and fall, creating tides.

Front

What is the equator?

Back

The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres.

Front

How does the position of the sun affect seasons?

Back

The position of the sun changes throughout the year due to Earth's orbit, affecting the amount of sunlight and warmth received in different areas.

Front

What is the significance of the solstices?

Back

Solstices mark the points in the year when the sun is at its highest or lowest point in the sky at noon, leading to the longest and shortest days.
