What makes something happen is called a cause. An effect is what happens as a result of the cause. Here are a few basics on writing a coherent cause and effect paragraph.
Decide whether to write about a cause or an effect or both. You can choose to discuss only the causes or only the effects of an event. Alternatively, you can discuss the causes AND effects of a certain event.
Make a list of causes or effects. Then narrow down that list to include only the most important causes or effects.
Write a draft explaining each cause or effect in the paragraph in as much detail as possible. and don't forget to use transitional words in your paragraph, such as: also, as a result, because, first and finally.
It is very important to include in your paragraph a clear topic sentence. This sentence should state the main idea of your paragraph.
Support your topic sentence with supporting details.
Edit your paragraph.
