Question

A section of the Southern Appalachian Mountains are located in Virginia (Select "Virginia"). Which mountain belt was next to the Virginia Appalachians at 200 Ma?

a. The Atlas Mountains

b. The Caledonian Mountains

c. The Greenland Mountains

d. The Mauritanian Mountains

Answer 1

Answer:

b. The Caledonian Mountains

Explanation:

200 million years ago (Ma), the Caledonian Mountains were next to the Virginia Appalachians. The Caledonian orogeny, or mountain-building event, occurred between the Late Silurian and Early Devonian periods (approximately 430-390 Ma). This orogeny formed a mountain belt that spans Scandinavia, the British Isles, eastern Greenland, and parts of eastern North America, including Virginia. The Virginia Appalachians and the Caledonian Mountains were part of the same ancient mountain range formed when the continents collided to form Pangaea, the supercontinent. However, due to erosion, tectonic activity, and other geological processes, these regions' current topography and geography have changed significantly over millions of years.

Answer 2

The Caledonian Mountains was the mountain belt next to the Virginia Appalachians at 200 Ma.
