Geological Features of the Green River

The video explores the geological mystery of why the Green River cuts through the Split Mountain anticline in Dinosaur National Monument. Geology Professor Sha Willy discusses the area's scenic beauty and geological features, including the resistant Weber Sandstone and softer Triassic beds. The video delves into historical explorations by John Wesley Powell and uses Google Earth to provide aerial and street views. It explains the concept of a superposed stream, where the river maintains its course through hard rocks due to geological evolution. The video concludes with a summary of the Green River's fascinating geological story.

What is the primary focus of the video regarding the Green River?

• The history of human settlement

• The scenic beauty and geological significance

• The recreational activities available

• The wildlife in the area

Why is the Green River's path through the Split Mountain anticline considered a geological puzzle?

• Because it disappears underground

• Because it changes direction frequently

• Because it cuts through hard rocks instead of taking an easier path

• Because it flows uphill

What historical figure is mentioned in relation to the Green River's geological puzzle?

• John Wesley Powell

• Charles Darwin

• Albert Einstein

• Isaac Newton

What tool is used to provide a visual understanding of the Green River's path?

• Aerial drones

• Topographic maps

• Satellite imagery

• Google Earth

What type of rocks make up the Split Mountain anticline?

• Sandstone and limestone

• Basalt and granite

• Igneous rocks

• Metamorphic rocks

What is a superposed stream?

• A stream that dries up seasonally

• A stream that changes its course frequently

• A stream that flows over a mountain

• A stream that maintains its course despite geological changes

How did the Green River maintain its course through the Split Mountain anticline?

• By changing its path frequently

• By flowing underground

• By eroding softer rocks

• By cutting through hard rocks

What is the significance of the gravel and conglomerate layer mentioned in the video?

• It indicates volcanic activity

• It shows the presence of ancient glaciers

• It was eroded away, exposing the anticline

• It is a source of precious minerals

What geological period is associated with the formation of the Split Mountain anticline?

• Pennsylvanian

• Triassic
