Rocky Mountains and Pluto Exploration

What geological process is primarily responsible for the formation of the Rocky Mountains?

• Subduction of tectonic plates

• Volcanic eruptions

• Sedimentation

• Erosion by glaciers

What is the Rio Grand Rift, and what potential impact could it have on North America?

• A tectonic fault line that could cause earthquakes

• A volcanic hotspot that could cause eruptions

• A river system that could flood the plains
