Why Japan has so many earthquakes

IN THIS ASSIGNMENT YOU NEED TO CHOOSE THE RIGHT ANSWER. SOME OF THEM ARE MULTIPLE CHOICE AND THE SOME OF THEM ARE WRITING SECTION.

QUESTION 1

1. A northerly wind in the northern hemisphere will transport water: to the wind's left to the wind's right downward upward

QUESTION 2

1. A pile of sediments of all different shapes and sizes was probably deposited there by: the wind a glacier/iceberg a river a mudslide

QUESTION 3

1. A trench and island arcs are characteristic of a certain type of: passive margin convergent plate boundary transform boundary Atlantic-type margin

QUESTION 4

1. As you move away from a mid-ocean ridge, which of the following would be observed: an increase in age of the sea floor a decrease in the thickness of sediments a gradual increase in mountains on the sea floor a shift from radiolarian oozes to diatomaceous oozes

QUESTION 5

1. Benjamin Franklin had his nephew produce the first map of the North Atlantic Ocean Gulf Stream Labrador Current U.S. coastline

QUESTION 6

1. Each of the following might be explained, entirely or partially, by the principle of isostasy EXCEPT: why Hawaii is sinking why a glacier depresses the land it travels over why Japan has so many earthquakes * how a guyot forms

QUESTION 7

1. In the Southern Pacific Ocean, the CCD is found at a depth of about 1500 meters. The average depth of the South Pacific Ocean is about 4000 meters. This means that you should find calcareous sediments over most of the South Pacific. you may find calcareous sediments in the South Pacific on top of a ridge. you won't find calcareous sediments in the South Pacific at all. siliceous sediments will not be found below a depth of 1500 meters.

QUESTION 8

1. John Harrison's work allowed the accurate measurement of: longitude latitude nautical miles wave height

QUESTION 9

1. Longitude was difficult to measure at sea because it was difficult to get an accurate measurement of star angles above the horizon time temperature ship speed

QUESTION 10

1. Riserless drilling has what advantage over riser drilling? It can drill more deeply into the earth's crust. It is more environmentally responsible. It is cheaper since it does not have a riser. It provides a more stable drill hole.

QUESTION 11

1. Submarine canyons are associated with which of the following: rift valleys continental slope trenches subduction zone

QUESTION 12

1. The coriolis effect exists because. the global winds exert such a large influence on currents. the speed of rotation at the equator is faster than at the poles. gravitational forces at the poles are greater than those at the equator. landmasses and continents interfere with air and water movement

QUESTION 13

1. The coriolis effect results in currents: Being deflected to their left in the Southern Hemisphere. Being deflected to the south in the Southern Hemisphere. Being deflected to the west in the Southern Hemisphere. Interfering with wave activity.

QUESTION 14

1. The deepest parts of the ocean are found at ocean ridges spreading centers seamounts trenches

QUESTION 15

1. The first oceanographic voyage taken purely for scientific reasons was by the Glomar Challenger HMS Challenger JOIDES Resolution Chikyu

QUESTION 16

1. The formation of a land breeze is similar to the formation of a: geostrophic current gyre summer monsoon downwelling

QUESTION 17

1. The impact Darwin made in the field of oceanography was to propose: a method by which a becalmed ship in the Doldrums might be able to move by harnessing penguins a theory explaining the phenomenon of El Nino to Captain Cook in the Hawaiian Islands a theory explaining how atolls form

QUESTION 18

1. The individual who comprised the book, The Physical Geography of the Sea was Matthew Maury James Cook Ben Franklin Bob Ballard

QUESTION 19

1. The mechanism causing the crustal plates to move is thought to be produced by convection in the mantle oceanic currents rotation of the earth tidal forces
   QUESTION 20
2. The present oceans have been created during the last 2,250 million years 200 million years * 20 million years 2 million years

QUESTION 21

1. The reason there are more calcareous sediments in the Atlantic Ocean has to do with: The latitude The size of the waves in the ocean The presence of hot spots The depth of the water

QUESTION 22

1. This explorer of the 1700's made several voyages on which he took a scientist. His sailors were called "limeys". Eratosthenes Columbus Magellan Cook

QUESTION 23

1. Which of the following statements describing the Jason/ARGO system of satellite and buoys is correct? Jason is the system of buoys, ARGO is the satellite The buoys dive and resurface, transmitting data to the satellite. The buoys are restricted to the Pacific Ocean. The buoys are restricted to the Atlantic Ocean.

QUESTION 24

1. Why can't reef-building corals live deeper than about 200 feet? There isn't enough oxygen in the deeper water. The waste products from the polyps will not diffuse into the deeper water quickly enough. The temperature is too cold in deeper water. The symbiotic algae in the polyp tissue needs more sunlight than is available in deeper water.

QUESTION 25

1. Why was Wegener's theory of plate tectonics not accepted? He could not explain HOW the plates moved. He had no real evidence. He was not a geologist. He was German and could not present his ideas well in English.

QUESTION 26

1. The diagram below depicts all of the following EXCEPT: an island arc a trench a convergent boundary a rift valley

1. Match the letters in the diagram with the earth layers they represent.

Mantle

Crust

Lithosphere

Asthenosphere

I.  D

II. C
III. B
IV. A

QUESTION 28

1. The island chain pictured was probably formed over a hot spot on land and was later submerged at a convergent boundary from migration of offshore sand bars

QUESTION 29

1. The following 6 characteristics describe differences between oceanic and continental crust. Choose the 3 differences that describe OCEANIC crust. Lower density Higher density Made of basalt Made of granite Thinner Thicker

QUESTION 36

1. Refer to the following diagram:

If a current leaves point "D", at which point will it end up?

point A        

 Point B
