Earth's Dynamic Geosphere book cover
AGI/It's About Time

Below are storylines that were designed by Cheryl Mosier, an Earth Science Teacher at Columbine High School in Littleton, Colorado.

Big Idea:

  1. The dynamic geosphere includes a rocky exterior upon which ecosystems and human communities developed and a partially molten interior with convection circulation that generates the magnetosphere and drives plate tectonics. It contains resources that sustain life, causes natural hazards that may threaten life, and affects all of Earth’s other geospheres.
  1. Natural hazards associated with Earth processes and events include drought, floods, storms, volcanic activity, earthquakes and climate change. They pose risks to humans, their property and communities. Earth science is used to study, predict, and mitigate natural hazards so that we can assess risks, plan wisely, and acclimate to the effects of natural hazards.

 

Activity 1 – Where are the Volcanoes?

Activity 3 – Volcanic Hazards: Flows

Activity 4 – Volcanic Hazards: Airborne Debris

Activity 5 – Volcanoes and the Atmosphere

Activity 6 – Volcanic History of Your Community

Activity 7 – Monitoring Active Volcanoes

Key Evidence Learned

- how maps are made & projected

- how topo maps are made and read

- how lava flows, pyroclastic flows and lahars are affected by volume, temp, slope and channels

- why ash covers a much larger area

- gases that come from a volcano

- how to read and interpret a geologic map

- volcanic monitoring

Connection to:

- closest volcanoes to us

- patterns of volcanoes on Earth

- most volcanoes are in the ocean

- where would lava flow on a volcano

- relationships between magma composition and type of volcanoe formed

- predict movement of lahars using topo maps

- hazards from each type of flow

- evacuation planning and decision making

- tephra and associated hazards

- scale of eruptions from the past

- ash movement is controlled by wind

- impact of volcanoes on global climate

- hazards of volcanic gases

- examine and identify igneous rocks in <STATE>

- closest volcanic rocks to Littleton

- what signs may signal an upcoming eruption
