Final answer:
Closed form poetry follows strict rules and patterns, while open form poetry is more flexible and allows for more freedom in structure.
Step-by-step explanation:
Form in poetry refers to the layout and structure of a poem on the page.
Closed form poetry follows strict rules and patterns, such as specific rhyming schemes and meter, while open form poetry is more flexible and allows the poet to create their own structure.
An example of closed form poetry would be a sonnet, which follows a set rhyme scheme and structure. An example of open form poetry would be a free verse poem, which does not follow a specific pattern or structure.
