Why does a tree have a hole, even if it is not made by humans?

Leave gold leaves, and the snow melts and leaves . a big "pothole"! Indeed, this happens all over the Canadian forests, especially around the trunk.

In a cold place like the forests in Quebec (Canada), the snow just started to melt. This is not worth mentioning if the snow doesn't melt . systematically like this!

Circles around the tree.

See, the snow starts to melt into a circle around the tree first. Any trunk, has fairly round "holes" , a definite cut and a vertical straight. Why is this strange phenomenon?

Hint: The physics knowledge of heat conduction will give you the answer.

Have you guessed it yet? The answer is, these holes are completely formed by heat. When the Spring sun warms the entire forest, dark stems should absorb more heat than the white snow.

The heat from the trunk radiates around. So the instant snow layer will melt first and leave round holes like that.

These holes are formed by heat.

In addition, the terrain of the forest is not flat, there are protrusions with recesses, leading to snow covering and melting at an uneven speed. This inadvertently creates other pits even though it is not surrounding the trunk. And they will not "be" and "beautiful" as we mentioned first.

A group of biologists in Quebec also discovered another interesting thing. There are many small plants that know how to "use" the space of the pits to start growing.

The reason is not only because these holes have created a favorable "open" land, but also because the body is always abundant in water and nutrients.

On the other hand, when you're small, you don't have much choice. Small trees only have a short time to immerse themselves in the sunshine. Soon, the snow will melt.

Many small plants know how to "use" the space of the pits to begin to grow.

Other plants will begin to shake themselves up, spring up and cover the "sunny sky" of the trees below.

At this time, the small tree can only close itself under the shade and wait for a new snow season, but they will never stop waiting for hope! Small but optimistic and strategic, right?
