This course focuses on a basic science understanding that demonstrates how the processes on Earth (including biological processes) lead to natural climate changes that have shaped the planet and the path of evolution. Students are challenged to think of the Earth as an integrated system made up on water, air, ice, land, and life.  

For example, students learn that the Gulf Stream is not the cause of western Europe’s temperate climate. They also learn that the rise of oxygen in the atmosphere 2.5 billion years ago produced massive extinctions of life on Earth that forever altered the dominant types of single-celled life.  Students are exposed to how new scientific discoveries are made through the observations that led to plate tectonics, how the Moon formed, and why dinosaurs went extinct.

课程大纲

1.  Basics

• How science works
• How Earth's climate works
• What is geologic time?
• Rocks and minerals
  

2. Early Earth history

• Formation of the Earth
• Formation of the Moon
• The first continents
  

3. Plate tectonics: How the Earth moves

• Earth's magnetic field
• Mid-ocean ridges and subduction zones
  
• Supercontinents
• Continent–continent collisions (Example: the Himalaya)
  

4. Climate interactions during geologic time

• The oceans: How they regulate the Earth's climate
• The cryosphere: Ice on our planet
• The atmosphere: Our protective layer and weather-maker
  

5. History of life on Earth

• Evolution of the atmosphere
• Single cells and hard shells
• Life on land
• Death from above (and below): Mass extinctions
