It is certainly true that nationalism has its upsides. A national consciousness led to the creation of states (instead of feudal regions or city-states) and remembering traditions and your history is important because it connects you to other people. However, being a national means identifying as something; hence , you are different from others. At some points, nationalism leads to despising other populations either because they are different and have different traditions or because they are simply unknown to us. In its worst instances, nationalism has led to nazism and genocide; the notion that a nation is better than another is the start of such actions. Hence, it is important that despite having a proud knowledge of our history and our identity, we also reach out towards other cultures, accept them and learn from them.

The water cycle or hydrologic cycle is the continuous movement of water between the earth's surface and the air. Water molecules move from the atmosphere (or air) to the earth's surface and back again. Water moves from the atmosphere to the earth's surface via rain, snow, sleet or hail. It moves back to the atmosphere via evaporation. The sun's energy is the catalyst for the movement of water between the atmosphere and the earth's surface.
