The Basics of Why It Rains
Rain is liquid water that falls to Earth. It is the liquid that gives life to plants and animals and is essential for industry and hygiene. Excessive rainfall can affect agriculture and drinking water. In order to get a better understanding of rain, it is important to learn the basics of the hydrological cycle.
The hydrological cycle refers to the constant process of condensation and evaporation of water on Earth. Water is a vital part of life on the planet, and it is constantly recycled between the oceans and the earth’s surface.
When a drop of water falls to the ground, it begins to saturate the underground water. The water then evaporates and saturates the river or lake. This water is then returned to its liquid form, and is re-saturated again. Eventually, it forms a reservoir in the earth’s crust.
Water is found in all parts of the world. However, certain regions are dry and do not have much moisture in the air. These areas may not experience any rainfall for several years. On the other hand, other regions of the world receive frequent rains. There are a number of factors that influence how much rain a region gets.
Temperature plays an important role in precipitation. The warmer the temperature, the more moisture the air holds. Therefore, the tropics tend to get a lot of rain. Colder air tends to hold less moisture. Furthermore, the more water vapor in the air, the higher the temperature of the air can rise.
The temperature of the air also has a huge impact on the amount of water that can condense into droplets. If the temperature drops to below freezing, ice will begin to form. Ice forms in the winter. However, ice can also form in the tropical latitudes.
There are many different factors that can contribute to the creation of a cloud that can be called a rain cloud. For instance, warm air can increase the water vapor in the air, and thus increase the chance that a cloud will become saturated with water. A cloud’s composition can also be an important factor. Specifically, a dark, thick cloud will have more water droplets and will therefore be heavier than a light cloud.
One of the main reasons for the formation of a rain cloud is the collision of water droplets. These tiny droplets of water are formed from even tinier particles called water molecules. Those particles are too small to form a visible droplet on their own, so they will form a visible droplet on their way down. Eventually, they will combine with other smaller water droplets to create a larger, heavier droplet.
Another important reason for the formation of a rain cloud is evaporation. When water vapor is present in the air, it will rise until it reaches its dew point, which is the temperature at which condensation occurs. Condensation of water occurs at warmer temperatures, and colder temperatures lead to snow and ice.
