The sun is much more massive than the moon. Why does the Moon affect the Earth's tides more than the Sun?
The Sun is closer to the Earth than the Moon.
The moon has craters, which creates more gravity.
The sun is too hot.
The sun is too far away, so it has less affect on Earth.
Compared with surface currents, deep currents are
colder and less dense.
warmer and less dense.
warmer and denser.
colder and denser.
Spring tides and neap tides occur in patterns governed by
changes in the force of Earth's gravity.
the type of ocean currents near where the tides occur.
whether the gravity of the sun or moon exerts a stronger pull.
the relative positions of the Earth, moon, and sun(the phases of the moon).
Using the map, which surface current is deflected by the continent of South America?
Gulf Stream
Canary
Brazil
N. Atlantic Drift
Which ocean is the smallest?
Pacific
Atlantic
Indian
Artic
Southern
Which Ocean is the largest and deepest?
Arctic Ocean
Indian Ocean
Pacific Ocean
Atlantic Ocean
Antarctic Ocean
What three could be true in the diagram?
full moon, lunar eclipse, neap tide
new moon, solar eclipse, neap tide
full moon, lunar eclipse, spring tide
new moon, solar eclipse, spring tide
Which of the following is the most dense?
Cold, salty water
Cold, fresh water
Warm, salty water
Warm, fresh water
Which type of tide is illustrated?
Spring tide
Neap tide
Summer tide
Winter tide
What is the primary driving force for surface ocean currents?
density layering
global winds
water temperature differences
salt concentration
How do warm-water currents affect the coastal areas where they flow?
They create greater rainfall along the coast.
They create unusually cool climates for the latitude.
They create unusually warm climates for the latitude.
They make coastal climate cooler than the inland climate.
What do scientists call the change in water temperature in the Pacific Ocean that produces a warm current and stops upwelling?
La Nina
El Nino
The Gulf Stream
Salinity
Which statement describes the negative effects of El Nino?
El Nino appears every 2 to 12 years.
Rain, flash-floods, and mudslides occur in places where there is usually little rain, while wet areas suffer from drought.
Sometimes El Nino is followed by La Nina, during which ocean temperatures become cooler.
Upwelling along the coast of South America occurs during El Nino.
Which of these features is found where the Atlantic Ocean is increasing in size?
Mid-ocean ridge
Continental Shelf
Trench
Abyssal Plain
Two high tides and two low tides occur every ______.
Year
Month
Week
Day
Which process increases the salinity of ocean water?
the Coriolis effect
convection currents
evaporation
continental deflection
If a low tide is at 6 a.m., what type of tide would be at noon?
low tide
high tide
If the sun, Earth, and moon are lined up as follows, the Earth would have __________________.
spring tides, which is when there is a maximum tidal range
spring tides, which is when there is minimum tidal range
neap tides, which is when there is a maximum tidal range
neap tides, which is when there is minimum tidal range
Where is the deepest part of the ocean?
continental shelf
trench
volcanic island
continental rise
What is the name of the area between the shoreline and continental slope (gradually sloping end of a continent that extends out under water)?
continental shelf
ocean trench
seamount
abyssal plain
Which areas of the ocean would have the greatest salinity?coastal water in a cool, humid area
coastal water in a cool, humid area
coastal water in a hot, dry area
coastal areas where a major river runs in
