I do not believe a longer school calendar is a good idea for a few reasons. One reason is that I believe kids need to have time to be kids and have some time off of school. Also, students wouldn’t tire out as easily with the ongoing overload of school. A con can be that childcare could be difficult to find when they are not in school and also that some kids do better with consistency and no break.

Man vs. Nature
The natural forces of the Earth are acting against him.
The edges of the continents are in a constant state of change caused by the ocean currents. Those currents can bring material with them, making the line more "smooth" and adding land to it, forming the so -called barrier beaches, or the sea can cause the land to fall into the water.
this change of edges over time and tectonic movement mean that the shape of the continents changes all the time: so the continents changed since the time of the split.
