Compare the four categories - definition, cause/effect, classification, and compare/contrast - for organizing supporting evidence in an explanatory essay. give an example of each.

Definition- Is something that is telling the meaning of a word.
Ex: Alpaca is a long-haired domesticated South America mammal that is related to a llama. 
Cause and Effect- The principle of causation. 
Ex: Cause- People keep using cars. Effect- Pollution of the air.
Classification-The action of classifying or grouping something by its qualities or characteristics. 
Ex: A spider is classified as Arachnida. 
Compare and contrast: Find the similarities and difference between an item or a word.
Ex: Dog and Cat- Dog is very active sometimes and a cat is lazy and calm. Both are mammals and can be a pet.

I hope this is helpful with some examples. :3
