Question 1: What natural phenomenon primarily shaped the rolling hills of the Palouse region?
- Erosion by rivers
- Windblown dust and fine silt
- Volcanic activity
Answer: Windblown dust and fine silt
Fact: The rolling hills of the Palouse were mainly shaped by windblown dust and fine silt, called loess. Over thousands of years, strong winds carried this dust and deposited it across the region. These thick layers of silt were then molded by wind and water into smooth, wave-like hills. Volcanic activity and rivers also played a role, but windblown silt was the main force.
Question 2: Which crops predominantly change the landscape colors in the Palouse throughout the seasons?
- Corn and rice
- Oats and soybeans
- Wheat and barley
Answer: Wheat and barley
Fact: The crops that mainly change the colors of the Palouse are wheat and barley. In spring, the fields look bright green as the plants grow. By summer, they turn golden as the crops ripen. In winter, after harvest, the land looks more brown and bare. This cycle gives the Palouse its famous rolling, colorful landscape.
Question 3: The Palouse region stretches to the borders of which two states besides Washington?
- Montana and Utah
- Idaho and Oregon
- California and Nevada
Answer: Idaho and Oregon
Fact: The Palouse region is mainly in southeastern Washington. It also extends into northwestern Idaho and a small part of northeastern Oregon. So, the correct answer is Idaho and Oregon.
