Example Questions

Example Question #2 : Daylight In Relation To Time Of Year

The sunrise and sunset change daily because the Sun changing its schedule.

Possible Answers:

False

True

Correct answer:

False

Explanation:

The sunrise and sunset do change daily, but not because of the Sun! The reason the times for sunset and sunrise change are because of the Earth's tilt and position. Depending on where the Earth is in its rotation and how it is tilted, the sunrise and sunset will change a little bit each day.

Example Question #10 : Daylight In Relation To Time Of Year

How is the sun different at noon than at 7:00 PM?

Possible Answers:

Its position in the sky is different.

It is hotter at 7 PM than at noon.

It is prettier at noon than at 7 PM.

Correct answer:

Its position in the sky is different.

Explanation:

The Sun is different throughout the day because of its position in the sky. At noon it will be directly above our heads in the sky. At 7 PM, the Sun will be setting so it will be low on the horizon or even beginning to disappear below the horizon depending on location and time of year.

Example Question #1 : Relate The Amount Of Daylight To The Time Of Year

What time of the year has the shortest days (least amount of sunlight)?

Possible Answers:

Spring

Winter

Fall

Summer

Correct answer:

Winter

Explanation:

The winter has the least amount of sunlight when compared to the other seasons. During the winter, because of the Earth's position, we have less direct sunlight leading to shorter days, cooler temperatures, and the least amount of sunlight.

Example Question #1 : Relate The Amount Of Daylight To The Time Of Year

What is the relationship between seasons and the number of daylight hours?

Possible Answers:

As seasons change, the number of daylight hours remains the same.

As seasons change, the number of daylight hours changes too.

There is no relationship between the seasons and the number of daylight hours.

Correct answer:

As seasons change, the number of daylight hours changes too.

Explanation:

There is a direct relationship between seasons and the number of daylight hours. During the spring and summer, longer days mean more daylight hours because of the Sun's tilt and position; during the winter, the days are shorter.

Example Question #3 : Relate The Amount Of Daylight To The Time Of Year

The order of the seasons changes every year.

Possible Answers:

True

False

Correct answer:

False

Explanation:

This is an untrue statement. The order of the seasons stays the same every year. The order is based on the Earth's revolution around the sun which does not change.

Example Question #4 : Relate The Amount Of Daylight To The Time Of Year

What seasons have the most amount of daylight?

Possible Answers:

Spring and summer

Fall and winter

Summer and fall

Correct answer:

Spring and summer

Explanation:

Spring and summer have the most daylight due to the Earth's position and tilt during these times. The days are longer which means more sunlight. During the summer solstice (the longest day of the year) parts of the world receive between 14 and 21 hours of sunlight!

Example Question #5 : Relate The Amount Of Daylight To The Time Of Year

What seasons have the least amount of daylight?

 

Possible Answers:

Spring and summer

Fall and winter

Winter and summer

Correct answer:

Fall and winter

Explanation:

The fall and winter have the least amount of daylight of the four seasons. The Earth's tilt and position cause the Earth to be tilted away from the Sun, so there is less sunlight, and the days are shorter.

Example Question #6 : Relate The Amount Of Daylight To The Time Of Year

A student predicts that summer will have longer days and more sunlight so he can play outside more when compared to winter. Is the student's prediction correct? Why or why not?

Possible Answers:

Yes, he is correct. The Earth is tilted towards the Sun during the summer and away during winter.

No, he is incorrect. There is more daylight in the winter than in the summer.

Yes, he is correct. The Sun moves towards the Earth in the summer and away in winter.

Correct answer:

Yes, he is correct. The Earth is tilted towards the Sun during the summer and away during winter.

Explanation:

The student is correct with his prediction. The Earth is slightly tilted, and during the summer, it is tilted towards the Sun, so we are warmer and get longer, sunnier days. During the winter, the Earth is tilted away from the Sun based on our position, so the days a colder, shorter, and there is less sunlight.

Example Question #7 : Relate The Amount Of Daylight To The Time Of Year

Rob is looking at the data table below and wants to relate the amount of daylight during different times of the year. What statement would best be supported?

Screen shot 2020 05 29 at 12.42.19 pm

Possible Answers:

There is the same amount of daylight during the whole year.

During the winter months, there is less daylight than in the summer months.

During the summer months, there is less daylight than in the winter months.

Correct answer:

During the winter months, there is less daylight than in the summer months.

Explanation:

Rob can conclude that during the winter months, there is less daylight than during the summer months. If there are only 9 hours of daylight in the winter but up to 15 hours in the summer, there is a relationship between the seasons and the amount of sunlight based on this data.

Example Question #8 : Relate The Amount Of Daylight To The Time Of Year

Based on the data table below, which conclusion is NOT correct?

Screen shot 2020 05 29 at 12.46.51 pm

Possible Answers:

Spring and summer get the most daylight.

Winter and fall get the least daylight.

Spring and fall get the same amount of daylight.

Correct answer:

Spring and fall get the same amount of daylight.

Explanation:

The conclusion that is NOT correct is that spring and fall get the same amount of daylight. Looking at the data table, we can see that spring receives 13 hours of daylight, and the fall receives 11 hours of daylight. These are not the same number, so this is an incorrect statement. The other answer choices are true statements based on the data.
