FAQ
How do I use this regions and landforms worksheet?
⌄
Begin with the physical map so students know the names. Then pair each text sheet with a wall map or atlas.
What does this worksheet teach?
⌄
Graph rainfall at six sample towns to see why farming changes at the 100th meridian. The directions on the page read: Read the text and study the table of made-up towns. You will need them for page 2. An answer key is included.
Can I use this regions and landforms worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade U.S. Regions and Landforms, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
Why is Death Valley so dry?
⌄
It lies in the rain shadow of the Sierra Nevada, where air that crossed the mountains has lost much of its moisture.
Why did trading towns grow along the fall line?
⌄
Boats sailing up from the ocean could go no farther, so goods had to be carried around the falls and towns grew at these stops.
Where does rainfall drop off in the Great Plains?
⌄
Rainfall thins steadily from east to west, and the change comes near the 100th meridian. The sheet graphs six sample towns to show it.
