Answers
1
Which of these global winds would bring
freezing cold
weather to Ohio in the winter?
Tropical Westerlies
Trade Winds
Doldrums
Polar Westerlies
2
An area's
long-term weather
patterns are known as it's _____________?
density factor
climate
wind direction
humidity
3
The amount of moisture or water in the air is called______________?
humidity
precipitation
air pressure
evaporation
4
Horizontal, stream-like movements of water found
at or near the surface
are called;
global winds
top currents
deep currents
surface currents
5
Where is the
Jet Stream
found?
In the upper Troposphere
In the Mesosphere
In the upper Exosphere
At the beginning of outer space
6
When
29,000 ducks
ended up in the ocean, it helped scientists to better understand__________?
The Gulf Stream
The Jet Stream
Deep ocean currents
Ocean surface currents
7
Which of these statements about ocean currents are
FALSE
?
Cold water has more density than warm water.
Water with high salinity (salt) is more dense.
Warm water has more density than cold water.
Ocean water becomes more dense when it cools
8
What are the
3 factors
that affect surface currents? (select 3)
The Coriolis Effect
water density
global winds
Continental deflection
9
A body of air with the same temperature and humidity is called a(n)_______?
global wind
convection current
air mass
polar ice cap
10
What is the
Jet Stream
?
Warm ocean currents
A global ocean conveyor belt.
Fast, strong-moving winds.
Slow-moving winds.
11
Ocean currents and winds travel in a
curved path
, due to Earth's rotation. This is called?
Coriolis Effect
Jet Stream
Continental deflection
Gulf Stream
12
Why does ocean water become more dense when it cools?
It has more salt in it.
The molecules of salt and water move apart making it sink.
Th heat from the sun makes the water sink.
The molecules of salt and water come together, and it sinks.
13
Winds to the NORTH and SOUTH of the equator travel which direction?
East to West
West to East
14
Wind, which travels over a body of water, creates friction. This creates a________________?
deep current
tornado
hurricane
surface current
15
Currents change course when they come into contact with continents. This is known as?
tidal waves
continental deflection
plate tectonics
coriolis effect
16
What is the driving
energy source
of global winds and ocean currents?
Heat from the Earth's core
The equator
The polar ice caps
The sun
17
Which of these statements is
TRUE
about our planet's oceans?
Earth's oceans are mostly freshwater.
Ocean levels are decreasing because of climate change.
Oceans are made up of about 90% deep currents
Oceans make up about 50% of Planet Earth.
18
The amount of
salt
in ocean water is called?
alkalinity
salinity
acidity
chemistry
19
How do
deep currents
form?
Global winds across the surface
Density decreases and water rises
Heat from the sun make water rise
Density increases and water sinks
20
Earth's wind and currents follow a
curved path
because of__________?
convection
tidal currents
earth's rotation on it's axis
gravity pull
21
Wind is moving air that is caused by differences in ___________?
air presssure
surface currents
density
climate
22
Which of these has the HIGHEST density? (HINT: It sinks!)
hot saltwater
cold saltwater
cold freshwater
hot freshwater
23
Ocean currents and global winds move in a
circular pattern.
This is called____________?
convection
rotation
conduction
radiation
24
Why does ocean water rise to the surface near the equator?
Heat causes molecules to warm up and move apart.
Heat causes molecules to warm and sink.
Scientist do not know why.
The equator cools ocean water.
