Study Notes
Interactions Between Spheres
- The biosphere, hydrosphere, lithosphere, and atmosphere constantly interact.
- Changes in one sphere affect the others.
- These interactions are crucial for ecosystem sustainability.
Interconnected Spheres
- The four spheres (biosphere, hydrosphere, lithosphere, and atmosphere) make up Earth.
- Changes in any sphere impact Earth's future.
- Earth's spheres are constantly interacting.
- For example, birds are part of the biosphere and fly through the atmosphere.
- Water is in the hydrosphere and flows through the geosphere.
- Soil is part of the lithosphere.
Events and Sphere Interactions
- An event is anything that alters one or more spheres.
- Changes in one sphere cause changes in others.
- Spheres are affected by natural and human events.
- Volcanic eruptions
- Storms
- Earthquakes
- Pollution
- Oil spills
- Human activities (building dams, shopping malls)
Cause and Effect Relationship
- Events cause changes within the spheres and/or are results of changes.
- Effects of interactions can be positive or negative, short-term or long-term.
Example: Forest Fire
- How might a forest fire affect the spheres?
- How might the fire be influenced by the current state of the spheres (hot, windy, rainy)?
Human Activity Affects the Spheres
- The world population has increased significantly over the last two thousand years.
- Growth was initially slow.
- In the late 1800s, growth exploded.
- Advances in technology and medicine increased human lifespans.
- In 1850 the average life expectancy in the U.S. was 43 years old. Today it is approximately 80.
- Life expectancy varies globally.
- The current global population is approximately 8 billion.
- Human activity has a profound impact on Earth's spheres.
