Contoh Explanation Text about Flood
The process of natural flooding is preceded by rain which falls to the surface of the earth. Then the rain water is absorbed by the ground surface and flows to the lower place. Once that condition happens, evaporation and the water appear to the surface of the land. Flooding can be disastrous for humans when floods happen in an area that people live because the water carries along objects like houses, bridges, cars, furniture and even people.
On the other hand, the process of non natural flooding is usually caused by bad habits of humans who do not care about the environment, such as littering that can make water flow clogged. This makes the water deposited in landfills which gradually becomes more common. When water reservoirs can no longer hold water discharge, the water then overflows out theland and cause flooding.

Examples of Explanation Text
Example of Explanation Text about Natural Phenomenon
How does Rain Happen?
Rain is the primary source of fresh water for most areas of the world, providing suitable conditions for diverse ecosystems, as well as water for hydroelectric power plants and crop irrigation.
The phenomenon of rain is actually a water circle. The concept of the water cycle involves the sun heating the Earth’s surface water and causing the surface water to evaporate. The water vapor rises into the Earth’s atmosphere. The water in the atmosphere cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation which can be in the form of rain or snow.
However, not all rain reaches the surface. Some evaporates while falling through dry air. This is called virga, a phenomenon which is often seen in hot, dry desert regions
Example of Explanation Text about Process of Making Chocolate
How Chocolate is Made
Have we wondered how we get chocolate from? Well this time we will enter the amazing world of chocolate so we can understand exactly we are eating.
Chocolate starts a tree called cacao tree. This tree grows in equatorial regions, especially in place such as South America, Africa, and Indonesia. The cacao tree produces a fruit about the size of a small pine apple. In side the fruits are the tree’s seeds. They are also known as coco beans.
Next, the beans are fermented for about a week, dried in the sun. After that they are shipped to the chocolate maker. The chocolate maker starts processing by roasting the beans to bring out the flavour. Different beans from different places have different qualities and flavour. So they are often shorted and blended to produce a distinctive mix.
The next process is winnowing. The roasted beans are winnowed to remove the meat nib of the cacao bean from its shell. Then the nibs are blended. The blended nibs are grounded to make it liquid. The liquid is called chocolate liquor. It tastes bitter.
All seeds contain some amount of fat and cacao beans are not different. However, cacao beans are half fat, which is why they ground nibs from liquid. It is pure bitter chocolate.
Example of Explanation Text – How a Cancer is Formed
How a Cancer is formed
What is cancer? It is actually a group of more than one hundred separate diseases. Most of us are fear from cancer It is reasonable because next to heart disease, cancer is the second leading cause of death.
Cancer cells come from normal cells because of mutations of DNA. Those mutations can occur spontaneously. The mutations may be also induced by other factors such as: nuclear and electromagnetic radiation, viruses, bacteria and fungi, parasites, heat, chemicals in the air, water and food, mechanical cell-level injury, free radicals, evolution and ageing of DNA, etc. All such factors can produce mutations that may start cancer.
Cancer cells are formed continuously in the organism. It is estimated that there are about 10,000 cancer cells at any given time in a healthy person. Why do some result in macroscopic-level cancers and some do not? First, not all damaged cells can multiply and many of them die quickly. Second, those which potentially divide and form cancer are effectively destroyed by the mechanisms available to the immune system. Therefore cancer develops if the immune system is not working properly or the amount of cells produced is too great for the immune system to eliminate.
