Asixth grader teacher take students on a field trip to the beach. one student finds several pebbles that have a rounded shape and are smooth to touch. what process most likely shaped these pebbles.

The pebbles probably went trough weathering or erosion.

Maybe I can answer the question a little better if you give me the answer choices. (if there are any)

dramatic irony occurs when the reader/audience knows more about a character's situation than the character does. the one main effect is that it gives the reader a sense of superiority, or detached superiority. the reader not only seemingly discovers what is revealed, but feels superior for doing so.

the best practice

1. keep your workspace clean

2. wash your hands

3. seperate and clean chemicals and equipment

4.   use microfiber cleaning utensils

5. clean and sanitize all work surfaces

hope this !
