¿Cómo se formó el Gran Cañón?

The Grand Canyon, a massive gorge on the Colorado Plateau, was formed through a combination of tectonic activity, erosion, and the persistent flow of the Colorado River. Over millions of years, the river carved through ancient rock layers, while tectonic shifts and glaciations contributed to the canyon's depth and width. Flash floods and ice further widened the canyon, creating the iconic landscape we see today.

What geological event initiated the formation of the Grand Canyon?

• The collision of the Pacific and North American Plates

• The formation of a large desert

• The impact of a large meteorite

• The eruption of a supervolcano

How did changes in sea levels contribute to the formation of the Grand Canyon?

• By forming a series of lakes

• By causing volcanic eruptions

• By creating large sand dunes

• By depositing layers of sedimentary rock and fossils

Where did the Colorado River originate before reaching the Colorado Plateau?

• The Rocky Mountains

• The Andes

• The Sierra Nevada

• The Appalachian Mountains

What natural process helped widen the Grand Canyon over time?

• Flash floods removing large chunks of rock

• Earthquakes creating new faults

• Volcanic eruptions depositing lava

• Wind erosion forming sand dunes

Which factors combined to create the Grand Canyon's landscape?

• Tectonic movements, glaciations, and erosion

• Volcanic activity, earthquakes, and landslides

• Wind erosion, desertification, and drought

• Meteor impacts, tsunamis, and hurricanes
