Question

question 5 (10 points) which pair best describes the physical process that caused its formation?
○ a great plains and asteroid impact
○ b mt. helena and earthquakes
○ c canadian shield and glaciation
○ d palo duro canyon and chemical weathering

Explanation:

• Option a: The Great Plains formed mainly from sediment deposition, not asteroid impact.
• Option b: Mt. St. Helens (assuming "Mt. Helena" is a typo) is a volcano, formed by volcanic activity, not mainly earthquakes.
• Option c: The Canadian Shield's landscape was significantly shaped by glaciation (glacial erosion and deposition), which is a correct pairing.
• Option d: Palo Duro Canyon was formed mainly by erosion (water erosion, a physical process), not chemical weathering as the primary process.

Answer:

c. Canadian Shield and glaciation
