After reading the website article above, your classmate wonders aloud about the iron ore deposits found along the Appalachian Mountains in the Eastern United States. There is no active plate boundary along the Appalachian Mountains, yet iron ore is known to form along plate boundaries. Why are there deposits of iron ore in a place where there isn't a current plate boundary?
9. Explain to your classmate how there can be mineral deposits located far from current plate boundaries.

Responses
The mineral deposits were moved to new underground locations by early miners.
These mineral deposits were formed by weathering, erosion, and deposition.
The mineral deposits have no geological explanation.
The mineral deposits were moved away from plate boundaries as the plates moved and collided over many years.
The mineral deposits found along the Appalachian Mountains were actually formed millions of years ago when tectonic plates were much more active in the region. During the formation of the mountains, there were subduction zones and collision events that led to the creation of these iron ore deposits. Over time, as the plates continued to shift and move, the mineral deposits were moved away from the original plate boundaries to their current locations along the Appalachian Mountains. So, even though there isn't a current active plate boundary in the region, the mineral deposits are a result of past tectonic activity.
whats the answer from the 4 responses above
The correct response is:
- The mineral deposits were moved away from plate boundaries as the plates moved and collided over many years.
are you sure
I apologize for the confusion earlier. The correct response is:
