  1. 10.21.13 Ecoregion Stations We will analyze the effects of erosion, weathering, and deposition on the environment in ecoregions of Texas by working in stations. Calculate the density of a substance that has a mass of 204 g and a volume of 18 cm3? Using the density , what is the name of the substance from the table? S

  2. 1. Explain what you need to know about ecoregions. 2. Explain what you need to know about watersheds P- • 7.8  Earth and space. The student knows that natural events and human activity can impact Earth systems. The student is expected to: • (A)  predict and describe how different types of catastrophic events impact ecosystems such as floods, hurricanes, or tornadoes; • (B)  analyze the effects of weathering, erosion, and deposition on the environment in ecoregions of Texas; and • (C)  model the effects of human activity on groundwater and surface water in a watershed.

  3. A- At each Station complete the chart

  4. C Chemical Weathering • What changes did you observe in the limestone rock after adding acid drops? • If the limestone pieces represent rocks in nature, what do the acid drops represent? • How is the action of chemicals like the action of wind and water? • What human activities may cause chemical weathering?

  5. C Wave erosion • What was the effect of the waves on the sand? • How does this activity relate to weathering, erosion, and deposition? • How do weathering erosion, and deposition by waves affect texas? • How do hurricanes affect weathering, erosion and deposition in Texas?

  6. C River Erosion • In your model what did the pouring water through the funnel represent? • What did adding water cause to happen? • How does the river act as an erosion agent?

  7. C Physical Weathering • What was the appearance of the marbles prior to being heated and cooled? • What was the appearance after? • What caused the chagne in the marbles? • What might happen to the cracked marble? • How does the cracking of the marble related to weathering of rocks? • Is weathering of rocks due to temperature chages, physical or chemical weathering? Why?

  8. C- put in and color the different ecoregions .

  9. E- Describe how catastrophic events affect the ecoregions in Texas! Use your vocab

  10. 10.22.13 Trashkit Review S A car travels at a constant speed of 30 m/s for 2 minutes. The car decreases its speed from 30 to 20 m/s during the next minute and then travels at a constant speed of 20 m/s for 2 more minutes. Which of the following graphs best represents the car’s motion during this 5-minute period? B A

  11. P • Things I need to know for my test: • Watershed, Weathering, Erosion, and Deposition. • Catastrophic events • Motion graphs / calculating speed • Calculating density • Flow of energy (Food web to energy pyramid)

  12. A/C - Trashkit Rules: • One person shoots at a time from each group. • Must have the correct answer and make the basket first • When the music stops you must be seated and quiet to listen to an explanation.

  13. Name an area where abiotic and biotic factors interact.

  14. A horrible natural event that affects an ecosystem is called…

  15. _______ is the breaking down of rocks.

  16. A _______ can result from excessive rain over a long period of time.

  17. The rabbits belong to which trophic level?

  18. How much energy will be available for the hawk if the primary consumers have 140,000 kcal?

  19. The amount of salt dissolved in a body of water is called _________.

  20. Which species of seed was affected the most by the amount of salinity in the water?

  21. The draining of all the water in a particular area to one location is called a __________.

  22. True or False An alluvial fan is a fan shaped deposit of sediments at the base of a hill or a mountain.

  23. How much energy is transferred from one trophic level to the next?

  24. A stack of books and its mass is shown below. Which of the following situations shows work being done? A. A student is sitting in a chair and holding the books.B. A student is holding the books 1 m above the floor.C. A student is standing and holding the books.D. A student is lifting the books 0.5 m from the floor to a table. 5 kg

  25. A ________ is a fan shape deposit of sediments at the mouth of a river.

  26. _______ is the settling of sediments in a new location.

  27. _______ is the carrying of sediments from one location to another.

  28. List three types of mechanical weathering in the pictures. 2. 1. 3.

  29. Name two types of weathering.

  30. 1. Fill in an energy pyramid using the web.2. Label trophic levels. 3. Fill in the energy available for every trophic level if herbivores have 250,000 kcal.

  31. What is the equation for calculating scientific work?

  32. Calculate the amount of work being done in situation A. Situation A F=30 N D=4 m Situation B F=60 N D=2 m

  33. Situation A F=30 N Calculate the amount of work being done in situation B. D=4 m Situation B F=60 N D=2 m

  34. Situation A Compare the amount of work being done in situation A to situation B. F=30 N D=4 m Situation B F=60 N D=2 m

  35. Situation A Explain why in both situations work ends up being the same. F=30 N D=4 m Situation B F=60 N D=2 m

  36. What is the volume of the cube if one of its sides is 3 cm?

  37. What is the formula for density?

  38. Sally has a toy car whose volume is 10 mL and its mass is 45 g. What is the density of her toy?

  39. What is the density of the following cube if the length of one of its sides is 2 cm and its mass is 28 g?

  40. . Calculate the Density of the ring. Show your solution!

  41. The density of water is 1.00 g/cm3. A  piece of wood that measures 8 cm by  5 cm by 3 cm has a mass of 80.0 grams.  What is the density of the wood?  Would the piece of wood float in water?  (volume = L x W x H)
