 Collection of marine debris in the Pacific Ocean  Convergence zone where warm and cold water meet and create a vortex

 4 ocean currents meet and circulate in a clockwise direction that is an area of about 20 million square kilometers.  The center is stable which is why garbage accumulates there.  The garbage is not biodegradable, it does not wear down, it just breaks into smaller pieces.  Area filled with tiny pieces of plastic that are eaten by sea creatures (and then we them….)

 Oceans  Seas  Lakes  Rivers  Streams  Gulf

 Continuous circulation of water between the atmosphere, oceans and earth.  Steps: 1. Evaporation: Water in atmosphere evaporates 2. Water Vapor: exists as vapor in the atmosphere 3. Condensation: cools and condenses into water 4. Precipitation: falls as rain/snow/ sleet/ hail 5. Water soaks into ground, flows into rivers, evaporates

 How do we know that water evaporates in the atmosphere?

 Assignment: How do humans interact with the hydrologic cycle?  Research “dead zone” in the Gulf of Mexico.  What is the “dead zone?”  Why does it exist (think about the role of humans)?  Write 1-2 paragraphs or create a visual representation of your findings  Due: Monday, October 27  -of-mexico-dead-zone/ -of-mexico-dead-zone/

 Describe the process of the hydrologic cycle in 3-4 sentences.

 Landforms: Naturally formed features on the surface of the earth  Continental shelf: earth’s surface from edge of continent to deepest part of ocean *oceans floors have similar landforms to earth’s surface (mountains, etc)  Topography: surface shape and composition of landforms and their locations in a given region.

 You will be assigned a landform  You must use page to define and draw an image of the particular landform you have been assigned.  Due by the end of the hour.
