This resource turns aral sea or amazon basin into a complete, ready to use review for Grade 9-12 earth science, covering the same NGSS standard from three different angles.

Sample questions include "Which of the following contributes to the loss of biodiversity in the Amazon Basin?", "Which human activity has significantly altered the Amazon Basin's ecosystem?", and "What impact does the drying of the Aral Sea have on local climate?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions

Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
