Chapter 18 Earth Science Word Study Erosion By Wind and Waves
Directions: Study the following words by reading and rereading them each
evening so you will be prepared for the word study test each week. You may
use one index card to write as many words and definitions on as possible to use
for the test. The card must written in ink, be in your handwriting, and have
your name, period, and chapter recorded in the top, right corner with no
obvious erasures or mark outs. If all the criteria are met, you may use your
index card during the test. It will then be stapled to your test.
