Unit 3 Test

Front

Why do we experience less sunlight in winter compared to summer?

Back

The Earth is tilted away from the Sun, resulting in shorter days and less direct sunlight.

Front

What shape does a planet's orbit resemble if its eccentricity is close to zero?

Back

A circle.

Front

How is the tilt of the Earth described during the spring and fall equinoxes?

Back

The Earth is tilted neither toward nor away from the Sun; the tilt is side to side.

Front

According to Kepler's 2nd Law, when do planets move the fastest in their orbits?

Back

Planets move fastest when they are close to the Sun.

Front

What is the difference between spring and neap tides?

Back

Spring tides occur when the Earth, Sun, and Moon are aligned during new or full moons.

Front

What causes the seasons on Earth?

Back

The tilt of the Earth's axis and its orbit around the Sun.

Front

What is eccentricity in the context of planetary orbits?

Back

Eccentricity measures the deviation of an orbit from being circular; a value of 0 indicates a perfect circle.

Front

What happens to the length of daylight during the summer solstice?

Back

The length of daylight is longest during the summer solstice.

Front

What is the significance of the equinoxes?

Back

During equinoxes, day and night are approximately equal in length.

Front

How does the gravitational pull of the Moon affect tides?

Back

The Moon's gravitational pull causes the water on Earth to bulge, creating high tides.
