Why are winter shadows longer than summer shadows?

Because the sun rises higher in our sky throughout the spring and summer months, heat and light reach our surface at a steeper angle. Similarly, in the winter, the sun's angle decreases, resulting in less concentrated heat and longer shadows. The length of a shadow is a function of both its height and its distance from the source of light.

The image below shows that winter shadows are longer than summer shadows. The tree in the center of the image receives no direct sunlight during the fall and winter months, so its shadow is always long. But notice how far back the edge of this shadow reaches into the spring and summer months when the sun is high in the sky all day long.

This image was taken in northern California near the city of Eureka. It's a small example of how one location can have different shadow lengths depending on the time of year.

The photo below shows that winter shadows can be very long. The trees in the foreground receive no direct sunlight, so their shadows are always long. But notice how far back the edge of this shadow extends into the spring and summer months when the sun is high in the sky all day long.

This image was taken in New Zealand's South Island near the town of Wanaka. It shows that even large trees can cast very short shadows in the wintertime.

Why are shadows longer in the fall?

Because of winter, or more specifically, the Earth's location in relation to the sun's shifting position as we all experience over the seasons. In the spring and summer, the sun is at a higher altitude, which causes shorter days and an increased number of hours of sunlight.

Fall is one of the only times of the year when you can see both the sunrise and sunset. This is because the sun sets in the west and rises in the east during the fall and winter months.

During the fall, the Earth is actually on average closer to the sun than it is in the winter, which explains why there is less sunlight during the dark days of winter and why we need more sleep then during the fall.

The length of a shadow is determined by two factors: the height of the object casting the shadow and the distance of that object from the center of Earth. Since fall is when the Earth is closest to the sun, its atmosphere has less effect blocking out light, so shadows are longer then in the winter.

Shadows become longer before and after the fall equinox because the Earth is not directly facing the sun. During these periods, half of the sky is illuminated and half is not, which creates shadows that are shaped like slices of pie.

Why is there a difference between the hours of sunshine during summer and winter?

The sunlight hitting the surface is more concentrated during the summer since the sun is higher in the sky. The sun is lower in the sky during the winter, and sunlight is spread out across a broader region. Both hemispheres receive roughly the same amount of sunshine in the spring and fall. But in the northern hemisphere, the days are longer during these seasons, while in the southern hemisphere, the nights are longer.

In addition to affecting when plants grow, the amount of sunlight reaching the ground also affects what types of plants can live here. Sunlight with a lot of ultraviolet light (UV) is dangerous for plants. If they aren't protected by clouds or trees, the UV rays would cause them to burn. Plants have ways of protecting themselves from UV rays - sunlight activates special chemicals found in plants that fight off harmful bacteria and viruses. Without this protection, plants would be overgrown with diseases caused by the UV rays.

So if you want to see flowers around your house all year long, try not to cut back too much on the sunlight during the winter months. This will help plants have time to recover before they're exposed to cold temperatures again.
