As we look around us, we will undoubtedly notice changes in nature. It's a cycle that comes and goes, but no matter how many times you have seen it, it's always fascinating to witness it again.

In preparation for this post, I went back to the question of why and how leaves change their color in the fall season. I won't bore you with many details, but a few notes might be of interest.

This here is only of course the start of the fall season. Much more intense colors are sure to follow.

As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter.

During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves.

As the bright green fades away, we begin to see yellow and orange colors. Small amounts of these colors have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll.

I want to end this post with a sneak peek!
Tomorrow we are going on a field trip to a National Historical Monument of Bosnia and Herzegovina. I won't say much, but the next image is only a part of it.

So come back tomorrow for the whole trip.

Have a great Sunday!
