Daylight Savings Time And The Solstices Quiz

Daylight Savings Time is the practice of adjusting clocks forward or backward by 1 hour to make better use of daylight during the summer months. This adjustment is typically done near a weekend midnight to minimize disruption to daily routines. By moving the clocks forward, people can enjoy longer evenings with more daylight, while moving them backward provides an extra hour of daylight in the morning.

The explanation for the given correct answer is that during the middle of summer, the Earth is tilted towards the sun, causing the sun to be in its northernmost position in the sky. This results in longer daylight hours and shorter nights, making it the longest day of the year. Additionally, the sun is also closest to the Earth during this time, further contributing to the longer duration of daylight.

During the middle of winter, the Earth is tilted away from the sun, causing the sun's rays to be spread out over a larger area. This results in less sunlight reaching any given location on Earth, making the days shorter. Additionally, during this time, the sun appears at its lowest point in the sky, which further contributes to shorter daylight hours. Therefore, the statement that the middle of winter is the shortest day in the year because the sun is the farthest to the Earth and in its southernmost position in the sky is true.

Daylight savings time, abbreviated as DST, is the practice of temporarily advancing clocks during the summertime. This is done to ensure that afternoons have more daylight and mornings have less. Clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. Therefore, the statement "All of the above" is correct as it includes all the information mentioned in the previous sentences.

Daylight savings time did begin in 1895. This is a true statement. Daylight savings time was first implemented in 1895 by George Hudson in New Zealand, who proposed the idea to make better use of daylight during the summer months. Since then, many countries around the world have adopted daylight savings time as a way to save energy and make better use of daylight.

Daylight savings time is used for multiple reasons. Firstly, it adds daylight to afternoons which benefits activities like retailing, sports, and other outdoor activities that rely on sunlight after working hours. Secondly, it aims to reduce the usage of incandescent lighting in the evenings, which is a primary but expensive type of lighting. However, its effect on health and crime is not clear and can vary. Therefore, the correct answer is "all of the above" as all of these reasons contribute to the use of daylight savings time.

The winter and summer solstices refer to the points in the year when the Sun reaches its highest or lowest point in the sky at noon, resulting in the shortest and longest days of the year respectively. During these solstices, the Sun appears to "stand still" in terms of its declination, meaning its position in relation to the celestial equator. This phenomenon occurs due to the tilt of the Earth's axis, causing different parts of the Earth to receive varying amounts of sunlight throughout the year.

The winter solstice in the Southern Hemisphere for 2011 happened on June 21st, while the summer solstice occurred on December 22nd.

Daylight Savings Time is put into action at the start of spring, end of autumn, and at 2 am on a Sunday. During these times, the clocks are adjusted forward or backward by one hour to make better use of daylight and save energy.
