The first day of fall in 2018 marked the beginning of a gradual decrease in daylight hours in the Northern Hemisphere. This decrease is due to the Earth's tilt on its axis and its orbit around the Sun. As the Earth orbits the Sun, the North Pole tilts away from the Sun, resulting in shorter days and longer nights.

• Facet 1: Changes in Sunrise and Sunset Times
  

  One of the most noticeable effects of decreasing daylight hours is the change in sunrise and sunset times. In the weeks following the first day of fall, the sun will rise later and set earlier each day. This is because the Earth is rotating on its axis and the North Pole is tilted away from the Sun.

• Facet 2: Impact on Human Activity
  

  The decrease in daylight hours can have a significant impact on human activity. For example, people may need to adjust their work and school schedules to accommodate the shorter days. Additionally, the decrease in daylight hours can lead to changes in mood and energy levels.

• Facet 3: Seasonal Changes
  

  The decrease in daylight hours is also a sign of the changing seasons. As the days get shorter and the nights get longer, the Earth prepares for winter. This can lead to changes in plant and animal life, as well as the onset of colder weather.

• Facet 4: Cultural and Historical Significance
  

  The decrease in daylight hours has cultural and historical significance in many societies. For example, in some cultures, the first day of fall is associated with the harvest and the preparation for winter. Additionally, the decrease in daylight hours has been used to mark the beginning of religious festivals and holidays.

The decrease in daylight hours is a natural phenomenon that occurs every year. It is a reminder of the Earth's changing seasons and its orbit around the Sun. The decrease in daylight hours can have a significant impact on human activity, plant and animal life, and cultural traditions.

Temperature

The first day of fall in 2018 marked the beginning of a gradual decrease in temperatures in the Northern Hemisphere. This decrease is due to the Earth's tilt on its axis and its orbit around the Sun. As the Earth orbits the Sun, the North Pole tilts away from the Sun, resulting in less direct sunlight and cooler temperatures.

The cooling temperatures of fall can have a significant impact on plant and animal life. Many plants begin to go dormant as the days get shorter and the temperatures drop. Animals also begin to prepare for winter by storing food and finding shelter.

The cooling temperatures of fall can also affect human activity. People may need to adjust their clothing and activities to accommodate the cooler weather. Additionally, the cooling temperatures can lead to changes in mood and energy levels.

Foliage

The changing color of foliage is a hallmark of the first day of fall in 2018. As the days grow shorter and the nights grow longer, the leaves on deciduous trees begin to change from green to vibrant shades of red, orange, and yellow. This process is caused by a decrease in chlorophyll production, which is the green pigment that gives leaves their color. As chlorophyll production decreases, other pigments, such as carotenoids and anthocyanins, become more visible.

The changing color of foliage is a beautiful sight, but it also serves an important ecological purpose. The shedding of leaves helps trees to conserve water and energy during the winter months. The fallen leaves also provide nutrients for the soil, which helps to support new growth in the spring.

The changing color of foliage is a reminder of the changing seasons and the beauty of the natural world. It is also a time to reflect on the year that has passed and to look forward to the year to come.
