Hydrosphere |
Is a dynamic mass of water that is continually on the move Includes: freshwater found underground, streams, lakes and glaciers |
|
|
Atmosphere |
The envelope of gasses surrounding the earth Shallow layer Provides air to breathe and protects us from UV Weather and climate |
|
|
Biosphere |
Includes all life on Earth The other 3 spheres would be completely different w/o this one |
|
|
Geosphere |
Extends from the surface to the center of the planet Lies beneath the atmosphere and the ocean Largest sphere |
|
|
Example of how these systems are interconnected |
Soil. The solid portion is a mixture of weathered rock debris (geosphere) and organic matter from decayed plant and animal life (biosphere). The decomposed and disintegrated rock debris is the product of weathering process that require air (atmosphere) and water (hydrosphere). |
|
|
System |
Is a group of interacting, interdependent, parts that form a complex whole |
|
|
Open System |
Matter goes in, matter goes out Energy flows |
Ex: hydrologic cycle |
|
Closed System |
Energy still flows, matter is inside and doesnt leave |
|
|

Purpose: to study the patterns and processes of the natural world To use the knowledge to predict expectations given specific conditions |
|
|
Describe the underlying assumptions of the scientific method of inquiry. |
See notes |
|
|
Describe the process of scientific inquiry. |

Terrestrial Planets |
Inner solar system Rocky Silicates, metallic iron Low mass (thin or no atmosphere) High density Closely spaced Few moons |
|
|
Jovian Planets |
Outer solar system Gasses and ices (H, He, ammonia, methane, carbon dioxide, water ices) High mass Low density Widely spaced Rings and alot of moons Long orbital periods |
|
|
Escape Velocity |
Speed required to escape a planets gravity |
|
|
Repeated collisions result in most of the material eventually collecting into asteroid-size objects called... |
Planetesimals Grains and clumps of icy, Rocky and metallic material |

|
|
Asteroids |
Leftover planetesimals Larger than 100 meters Asteriod Belt: they orbit btw mars and jupiter Orbit around the sun |
|
|
Comets |
