Pаrt 5: Shоrt аnswer [12 pоints eаch; 24 pоints total] Answer TWO of the following questions.Do not answer all of them! Just two!! Regardless of which questions you choose, you MUST include a labeled diagram to support your answers. (1) If you are answering question 1, respond to the following: Draw a series of labeled diagrams illustrating the stages of coral reef development from youngest to oldest. These can be map views or side views, your choice. List and specifically describe 3 ocean characteristics that are important for coral reef development and WHY each of these characteristics is necessary for the development of coral. (Note: there are definitely more than 3 options here, so don't feel like there are "only" 3 things to talk about. There are a lot of different directions you could go with this.) Describe the phenomenon known as coral reef bleaching, including the causes, what happens during bleaching, the impact of bleaching on the reef, and what a reef that has experienced bleaching looks like. Can reefs be rehabilitated once they have been damaged? If so, please describe what you learned in class about how this is done. (2) If you are answering question 2, respond to the following: Consider a pile of rock fragments on land. Describe what will happen to the size, shape, and sorting of these rock fragments as they get moved further and further from their source. Draw a side-view sketch of a continental margin and a deep ocean basin. (It doesn’t need to be super-detailed, just a simple sketch.) In your sketch, please indicate where the following types of sediment would be most abundant: coarse (large) pieces of lithogenous sediment; fine (small) pieces of lithogenous sediment; ooze In oceanography, what does “ooze” mean? What is ooze composed of? (Be as specific as possible.) Consider a pile of ooze on the seafloor. Which specific type of ooze would you expect to be most abundant if this was an equatorial ocean? Which specific type of ooze would you expect to be most abundant if this was a polar ocean? (3) If you are answering question 3, consider a set of waves that are 3 feet tall and separated by 30 feet. After 30 seconds, 3 waves have passed a fixed point. Calculate the celerity of this set of waves. What will happen to the speed of these waves as they approach the beach? WHY? How deep would one need to dive below the surface of the ocean to no longer be affected by wave motion? What will happen to the wavelength of these waves as they approach the beach? WHY? At their current location, are the waves breaking? (Yes or no.) Explain.
QUESTION 1 A bus trаvels аlоng а straight rоad. The graphs shоws how the velocity of the bus changes during a short journey. Refer to the addendum Figure 1.1 1.1 State the velocity of the bus after 15 s. (1) 1.2 How long is the bus stationary during the 60 s. (1) 1.3 State the equation linking acceleration, change in velocity and time taken. (1) 1.4 Calculate the acceleration of the bus during the first 10 seconds. Give the unit. (3) 1.5 Calculate the distance the bus travelled in the first 30 seconds. (2) 1.6 State the equation linking average speed, distance moved and time taken. (1) 1.7 Calculate the average speed of the bus during the first 30 seconds. (2) 1.8 The bus travels further in the first 30 seconds than it does in the last 30 seconds. Explain how the graph shows this. (2) 1.9 Draw a free body force diagram to show all the forces acting on the bus during the time from 20 – 30 seconds. (4) (Total for question: 17)
QUESTION 3 A cаr driver sees а hаzard оn the rоad ahead. The graph shоws the velocity of the car from when the driver sees the hazard. Refer to addendum Figure 3.1 3.1 With the use of the graph, determine the reaction time of the driver. (1) 3.2 Calculate the stopping distance of the car. (4) 3.3 Calculate the acceleration of the car when the car is braking. (3) 3.4 The speed of the car affects the thinking distance and the braking distance. Discuss other factors that affect the thinking distance and the braking distance of the car. (4) (Total for question: 12)
