LEAP Earth-Sun-Moon System Patterns 4

Question 1

A student in New Orleans observes shadows at noon. In which month would noon shadows be shortest?

Accepted Answer

June

Answer

In June, the summer solstice causes the Sun to be highest in the sky at noon in the Northern Hemisphere, producing the shortest shadows.

Question 2

What is the primary reason Earth experiences seasons?

Accepted Answer

The tilt of Earth's axis as it orbits the Sun

Answer

Earth's 23.5-degree axial tilt causes different hemispheres to receive more direct sunlight at different times of year, creating seasons.

Question 3

Which of the following correctly describes a neap tide?

Accepted Answer

A moderate tide when the Sun and Moon are at right angles to Earth

Answer

Neap tides occur during quarter moon phases when the Sun and Moon are at right angles relative to Earth, producing less extreme tidal differences.

Question 4

A total lunar eclipse can only occur during which Moon phase?

Accepted Answer

Full moon

Answer

A lunar eclipse occurs when Earth's shadow falls on the Moon, which is only possible when the Moon is on the opposite side of Earth from the Sun—during a full moon.

Question 5

How does Earth's axial tilt affect the length of daylight hours in Louisiana during winter?

Accepted Answer

Louisiana has fewer daylight hours in winter because the Northern Hemisphere tilts away from the Sun

Answer

In winter, the Northern Hemisphere tilts away from the Sun, reducing the angle and duration of sunlight, giving Louisiana shorter days.
