Coriolis effect
What term is used to describe the large, whirlpools of water that occur in all ocean basins?
(a)
Describe Anarctica's climate in this picture.
warm and tropical average temp = 80s
cool average temp = 70s
cold and frigid like today
In what direction to gyres flow in the Southern hemisphere?
clockwise
anticlockwise (counter clockwise)
How does the temperature of the east coast of South America compare to the west coast of South America?
The east coast is colder than the west coast
The east coast is warmer than the west coast
The east and west coasts have about the same temperature of water
How does the temperature of the east coast of United States of America compare to the west coast of the United States of America?
The east coast is colder than the west coast
The east coast is warmer than the west coast
The east and west coasts have about the same temperature of water
Alcatraz Prison was and island located off the coast of California and was considered to be inescapable. What is one reason Alcatraz was thought to be inescapable?
The guards were known for their vigilance
Inmates were selected for their inability to swim
The current surrounding the prison is strong and very cold
The view from the island was beautiful and no one wanted to leave
Gyres are known as
vertical, density currents
surface currents
Surface currents are influenced by prevailing winds. The currents flow in the
opposite direct as the prevailing wind
same direct as the prevailing wind
What evidence did scientists use to infer the climate of Antarctica 60 MYA?
The amount of snow and ice that accumulated
Data left previous expeditions
Fossils from plants- pine trees and ferns
What is true about all currents on the west side of ocean basins?
shallow, deep, and wide
slow moving and only current to not touch land
fast, deep, and narrow
What is the name of the only current to completely circle Earth without hitting land?
(a)
There are 5 large gyres in the worlds oceans. Which is NOT one of the major gyres?
North Indian
South Indian
North Pacific
South Pacific
North Atlantic
What is unique about the gyres in the north Indian Ocean?
They rotate anticlockwise while all other northern hemisphere gyres spin clockwise
They are composed of half warm water and half cold water currents
They cause the hurricane season
They do not contain any cold polar water
The oxygen content in warm water is ___ the amount of oxygen in cold water.
less than
greater than
When oxygen content is low, octopus tend to stay in
shallow water
deep water
Deep water octopus species have well developed ink sacs
true
false
Why are ink sacs not necessary for deep water octopus species?
There are few predators in deep water
Ink is not effective camoflauge in deep water
High oxygen content in deep water negates the ink
How did octopus move from the Pacific Ocean to the Atlantic ocean?
South America moved away from Antarctica leaving a passage
They crawled across the land
They were transported by wind
Why did Antarctica have a mild 74 degree temperature 65 MYA?
It was positioned closer to the equator than it is today
It was touching South America and was close to Africa. Both are warm countries.
It was being heated by a warm water current from a gyre
