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.
