 Introduction to Oceanography 

Please enter answers on a Scantron sheet, using a #2 pencil Homework 1

 

1. If we shot a cannonball 200 miles in a southerly direction from Greenwich Observatory in England would it end up:

 

a) At a positive (+) latitude and longitude.

 

b) At a negative (-) latitude and longitude.

 

 c) At a positive (+) latitude and negative (-) longitude.

 

d) At a negative (-) latitude and positive (+) longitude.

 

e) At a positive (+) latitude and on the prime meridian.

 

2. In the schematic below, please identify where the oldest oceanic crust can likely be found.

 

a) b) c) d) e)

 

At site 1.

 

At site 2.

 

At site 3.

 

Sites 1 and 3 are equally old.

 

 All of the sites have the same age.

 

3. Evidence for past ‘super continents’ include all of the following except

 

a) Mountain ranges of similar age and size on east and west of Atlantic

 

 b) Similar glacial deposits in South America, Africa, India and Australia

 

c) Hot spot activity along the Hawaiian-Emperor Seamount Chain.

 

d) Matching fossils found in South America and Africa of animals that could not swim across an ocean

 

 4. Looking at the lecture slide on plate boundaries and relative plate movements, which of the following cities would you expect to have the most earthquakes?

 

 a) Sydney

 

b) Tokyo

 

c) New York

 

 d) Cape Town e) Rio de Janeiro

 

5. Which of the following is FALSE about solar heating?

 

a) The earth would absorb more heat if it had less snow and ice cover.

 

b) Light is less dispersed in the low latitudes than in the high latitudes.

 

c) When it is Spring in the Southern Hemisphere, the Northern Hemisphere receives substantially less light.

 

 d) Incoming and outgoing radiation are about the same.

 

e) The earth’s heat is redistributed by ocean currents and atmospheric circulation.

 

 6. What would happen to Earth’s seasons if its inclination (tilt) decreased from its current angle of 23.5 to 22 degrees?

 

a) Earth would have warmer summers and colder winters (stronger seasonality)

 

b) Earth would have cooler summers and warmer winters (weaker seasonality)

 

c) The summers and winters would both be warmer.

 

d) The summers and winters would both be cooler.

 

e) There is no effect on the seasons.

 

7. We talked about the amount of solar energy different latitudes receive on our planet. Now assume a cylindrical planet (see picture on right) that rotates around its own axis (without any inclination) and around a central star. On which point of the diagram would the planet receive the most light energy? Note that just like in our SunEarth system, the size of the central star is much larger than the planet.

 

 a) b) c) d) e) A D B C A B C D Each of the four points would receive the same amount of light energy.

 

8. How does the Coriolis Effect affect a parcel of air moving across latitudes?

 

a) It deflects the parcel of air to the right in both hemispheres.

 

b) It deflects the parcel of air to the left in both hemispheres.

 

c) It deflects the parcel of air to the left in the Northern Hemisphere, and to the right in the Southern Hemisphere.

 

d) It deflects the parcel of air to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere. e) The parcel of air turns clockwise in both hemispheres.

 

 9. Imagine you are standing on the coast of Antarctica during the Southern Hemisphere winter. The air temperature on land is -10°C, while a mile offshore the surface ocean water is a relatively balmy +5°C. In the convection cell depicted by the dashed line on the image below, please indicate the correct pressure condition and air movement associated with this temperature regime.

 

 a) low pressure at point A, air rises at this location.

 

b) low pressure at point B, air rises at this location.

 

c) high pressure at point A, surface wind blows from B to A.

 

d) high pressure at point B, surface wind blows from A to B.

 

10. Using the picture below, please select the letter that marks the zone of lowest pressure in this Northern Hemisphere cyclone.

 

 A – spiral rain bands

 

 B – outer bands of low cloud cover

 

C – eye of the hurricane

 

D – eye wall

 

 E – outer bands of intermediate cloud cover
