  1. How natural processes affect our oceans and land Continental and Oceanic landforms How waves, currents, tides, and storms affect the geologic features of the ocean shore zone Waves, Currents, and Tides How humans affect our land and oceans 5 pt 5 pt 5 pt 5 pt 5 pt 10 pt 10 pt 10 pt 10 pt 10 pt 15 pt 15 pt 15 pt 15 pt 15 pt 20 pt 20 pt 20 pt 20 pt 20 pt 25 pt 25 pt 25 pt 25 pt 25 pt

  2. What is the definition of weathering?

  3. What is the definition of weathering? The processes that break down rocks at or near the surface of the earth. Weathering can be either physical or chemical.

  4. Choose any natural processes and give an example of it being constructive and deconstructive.

  5. Answers will vary. Example: Volcanoes exploding can create land= constructive, or destroy land = deconstructive. Floods can carry nutrients to rivers= constructive, or destroy homes and businesses = deconstructive.

  6. What is the definition of erosion and deposition? Provide an example of each.

  7. Answers will vary. Erosion= the movement of sediments by wind, water, and ice. Example: A rock being carried off by the wind. Deposition = the depositing of sediments by wind, water, and ice, usually building up new land. Example: A delta being formed at the end of a river.

  8. Explain how the following can happen: • Earthquakes • Landslides • Volcanic Eruptions

  9. Earthquakes: vibrations in the Earth’s surface from sudden movement along a fault line. Landslides: A mass movement of land due to gravity. Volcanic Eruptions: Magma emerging from the earth’s crust.

  10. Create a short story about the journey of a rock through weathering, erosion, deposition, and ONE other natural process such as landslide, volcanic eruption, earthquake, or flood.

  11. Answers will vary. Example: While sun bathing on my glorious cliff one day I saw storm clouds begin to develop. The wind soon picked up speed and the waves began crashing. I was broken off my cliff and fell down into the sea. While down below the ocean I was tossed and turned and broke apart! (weathering) The currents took me all the way across the continent (erosion) where I was dropped off as a piece of sand and I helped create a sand dune! (deposition) The next month was great, until the day of the big flood. I was then carried all the way into someone’s house!! A few days later I was swept up and landed in a kids sand box! I’m loving it here, for now….

  12. Identify the ocean floor landform A and G

  13. A = Continental Slope G = Trench

  14. Identify the ocean floor landform B, C, D, and F.

  15. B = Seamount C = Abyssal Plain D = Mid- Ocean Ridge F = Continental Shelf

  16. Complete the chart:

  17. Complete the chart

  18. Identify all the different ocean landforms used in the movie Finding Nemo

  19. Continental Shelf is where Nemo lived. Nemo traveled out to the Continental Slope to touch the butt of the boat. Nemo and Dory didn’t swim through the trench. Nemo and Dory went to the abyssal plain when they met with the lantern fish.

  20. What is the definition of an inlet?

  21. Inlets are water filled spaces between barrier islands.

  22. Compare and Contrast a barrier island to a estuary

  23. Barrier island is a sandy piece of land surrounded by water on ALL sides. Currents can change its shape. Estuary is an area where river meets an ocean. Here there is a mixture of salt and fresh water.

  24. Compare waves, tides, and currents. Define each one.

  25. Waves- the movement of water, primarily caused by winds. The highest part is called the crest. Tides- the regular rise and fall of water in oceans caused by the pull of the moons gravity on Earth. Currents- Flowing streams of water that move continuously through the ocean in a specific direction.

  26. If high tide is at 8am, when will the next high tide be? Why is there high and low tide?

  27. The next high tide will be at 8PM The tides change because of the pull of the moon’s gravity on Earth.

  28. TWO times a month these special tides occur. How many times do low and high tides happen?

  29. High and low tides occur twice a day (totally 4 times) Neap tide= really low tide Spring tide = really high tide

  30. Identify whether the situation is caused by waves, currents, or tides: Sand is carried from the northern end of the Isle of Palms and deposited on the southern end.

  31. Identify whether the situation is caused by waves, currents, or tides: Sand is carried from the northern end of the Isle of Palms and deposited on the southern end. CURRENT

  32. Identify whether the situation is caused by waves, currents, or tides: The shoreline is continuously changing as shells, sand, and sediments are brought in and left behind at various times throughout the day.

  33. Identify whether the situation is caused by waves, currents, or tides: The shoreline is continuously changing as shells, sand, and sediments are brought in and left behind at various times throughout the day. WAVES

  34. Identify whether the situation is caused by waves, currents, or tides: The salinity of the water in the estuary changes at different times of the day.

  35. Identify whether the situation is caused by waves, currents, or tides: The salinity of the water in the estuary changes at different times of the day. TIDES

  36. Identify whether the situation is caused by waves, currents, or tides: Towns and area located by the ocean are destroyed by Tsunamis.

  37. Identify whether the situation is caused by waves, currents, or tides: Towns and area located by the ocean are destroyed by Tsunamis. WAVES

  38. Identify whether the situation is caused by waves, currents, or tides: Warm and cold water are moved to different regions of Earth as a result of this.

  39. Identify whether the situation is caused by waves, currents, or tides: Warm and cold water are moved to different regions of Earth as a result of this. CURRENTS

  40. What does conservation mean? Give an example.

  41. Conservation: • Human activities that help to keep the natural resources of Earth available and clear of pollution are conservation efforts. • Example: Reduce, reuse, recycle

  42. What does pollution mean? Give an example.

  43. Pollution is anything that harms the natural environment. • Examples: littering, smoke fumes, oil spills, etc.

  44. Identify if this is an example of conservation or pollution: Strip mining

  45. Identify if this is an example of conservation or pollution: Strip mining Pollution

  46. Identify if this is an example of conservation or pollution: Dumping wastes into water & Planting trees

  47. Identify if this is an example of conservation or pollution: Dumping wastes into water POLLUTION & Planting trees CONSERVATION

  48. List 5 ways you can help conservation efforts.
