Friday 5 on Friday the 13th!!!
1. Define and provide an example of gradation.
-Gradation is the processes that lead to the gradual leveling or smoothing of the Earth's surface over time through natural forces. It's the shaping of the land. ex. glaciers eroding and scraping the E's surface
2. List the 5 main spheres/subsystems.
Hydrosphere, Biosphere, Cryosphere, Atmosphere, Lithosphere
3. Provide an example for two spheres:
Atmosphere = the air we breath
Biosphere = animals and humans
Cryosphere = glaciers (ice)
Lithosphere = rocks and minerals on the E's surface
Hydrosphere = rivers and lakes
4. What are the two main types of glaciers?
Continental & Alpine
5. Explain the three main concepts of gradation.
Erosion - the process of wearing away the rocks and soil
Transportation - the movement of eroded materials
Deposition: - the accumulation of eroded materials to a new location
Bonus:
What is a system?
-A system is a collection of interdependent parts enclosed within a defined boundary.
