The Gulf Stream affects the climate of Northern Europe by:
warming the region, making it milder than other areas at similar latitudes
cooling the region, making it colder than other areas at similar latitudes
having no significant effect on the climate
causing extreme weather conditions
Which ocean current is responsible for warming the climate of Northern Europe?
El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. What is El Niño?
A climate pattern causing unusual warming of surface waters in the eastern tropical Pacific Ocean
A type of fish found in the Pacific Ocean
A weather phenomenon that cools the Atlantic Ocean
A type of cloud formation

Tornado
Which of the following is a characteristic of El Niño?
Cooler ocean temperatures
Warmer ocean temperatures
Increased rainfall in the Northwest
Decreased rainfall in the Southeast
Which of the following is a characteristic of La Niña?
Warmer ocean temperatures
Cooler ocean temperatures
Increased rainfall in the Southeast

El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. How does it affect weather patterns?
It causes droughts in some regions and heavy rainfall in others.
It leads to a decrease in global temperatures.
It has no significant impact on weather patterns.
It causes a uniform increase in rainfall worldwide.
The difference between El Niño and La Niña is:
El Niño is characterized by warmer ocean temperatures in the Equatorial Pacific, while La Niña is characterized by cooler ocean temperatures in the same region.
El Niño is characterized by cooler ocean temperatures in the Equatorial Pacific, while La Niña is characterized by warmer ocean temperatures in the same region.
Both El Niño and La Niña are characterized by warmer ocean temperatures in the Equatorial Pacific.
Both El Niño and La Niña are characterized by cooler ocean temperatures in the Equatorial Pacific.
Deep ocean currents affect global climate by:
regulating temperature and distributing heat around the planet
causing earthquakes and volcanic eruptions
increasing the salinity of the ocean
decreasing the amount of marine life
Salinity plays a role in ocean currents by affecting:
temperature of the water
density of the water
color of the water
clarity of the water
The Coriolis effect is responsible for:
the deflection of wind and ocean currents due to Earth's rotation
the increase in ocean temperature near the equator
the decrease in salinity of ocean water
the formation of oceanic trenches
The average sea surface temperature decreases between November 2015 and April 2016 due to:
El Niño effect
La Niña effect
Global warming
Seasonal changes
How can you use sea ice to investigate the effect of ocean salinity? Fill in the blanks: Sea ice forms from ________. The ice ________ salt. Sea ice ________ the salinity of the ocean water.
Sea ice forms from freezing seawater. The ice excludes salt. Sea ice decreases the salinity of the ocean water.
Sea ice forms from melting glaciers. The ice absorbs salt. Sea ice increases the salinity of the ocean water.
Sea ice forms from freshwater lakes. The ice mixes salt. Sea ice maintains the salinity of the ocean water.
Sea ice forms from rainwater. The ice dissolves salt. Sea ice has no effect on the salinity of the ocean water.
