AICE Marine Science Chapter 2 Practice Test Verified Answers

AICE Marine Science Chapter 2 Practice Test Verified Answers 1a Define what is meant by the term littoral zone. [ 1 ] the area of a shoreline that is submerged during high tide and exposed during low tide 1b Compare the formation of a rocky shore to the formation of a sandy shore. (4) Rocky shores form by exposed to high amounts of erosion, little sedimentation and high wave action. While, sandy shore is less erosion, more sedimentation, water is moving slower but still has wave action and it is more gradual slope 1c State a defining feature that distinguishes a delta from an estuary. (1) Estuaries are have more protected and sheltered barrier that protect from waves, while the deltas are more open 2a State three major lines of evidence supporting the theory of plate tectonics. (3) Continents fit together like puzzle pieces. Similar fossils on different continents and paleomagnetic stripes 2b Describe the movement at each of the following plate boundaries and state one feature located there: i. transform boundary (2) ii. convergent boundary (2) iii. divergent boundary. (2) i. The movement of transform boundary is tectonic plates slide past one another, such as earthquakes. ii. The convergent is when tectonic plates move toward each other, such as ocean trenches or volcanoes. iii. The divergent boundary is when tectonic plates move away from each other, such as mid ocean ridges. 3a State where you would expect to locate hydrothermal vents. (1) mid-ocean ridges along divergent plate boundaries 3b Outline how hydrothermal vents form. (4) The hydrothermal vents form by cold water along the ocean floor sinks through cracks in Earth's crust. Then, water moves through the crust to dissolving minerals. Magma under crust superheats the water. Water will escapes through a vent on the sea floor. After that, the water cools and the minerals fall out of the solution. At the end, it builds up the chimney of the hydrothermal vent. 3c Hydrothermal vents are considered to be extreme environments. Describe how that may impact the organisms that live there. (3) It may impact the organisms that live there by the organism must adapted to high temp., high pressure, lack of light that prevent to photosynthesis, and presence of toxic chemicals in the water 4a Using the data in Table 2.4, describe the effect of pressure on the attachment of Tevnia larvae.
