As we travel north or south on Earth, we do observe a noticeable change in the angle of the Sun's rays. This change in the angle of the Sun's rays is one of the factors responsible for the changing seasons as well.
The angle of the Sun's rays reaching a particular location on Earth depends on the latitude or the distance from the equator. When you move closer to the poles, the Sun's rays arrive at a more oblique angle, leading to lower temperatures and shorter days. Conversely, as you move closer to the equator, the Sun's rays arrive at a more direct angle, resulting in higher temperatures and longer days.
The variation in the angle of the Sun's rays is more pronounced when comparing extreme latitudes. For example, if you were to travel from the equator to the North Pole, the change in the Sun's angle would be substantial. However, the difference may not be as noticeable when traveling shorter distances, such as from one city to another within a moderate latitude range.
It's also worth noting that the changing angle of the Sun's rays is a gradual process that occurs over the course of seasons rather than being immediately apparent during short journeys. If you were to track the Sun's position at the same time each day over several months, you would observe a distinct pattern of movement and changing angles.
In summary, while the change in the angle of the Sun's rays may not be immediately noticeable during short travels, it is indeed observable and plays a significant role in seasonal variations as we move north or south on Earth.
