Climate Change
What climate condition occurs during El Niño? dry heat throughout North America warm water moving toward the coast of South America heavy rain moving toward the coast of South America flooding throughout North America
b
What effects do wind patterns have on climate? They move warm water toward the east. They change the amount of precipitation in an area and affect a region's climate. They carry warm or cooled water very long distances. They cool Pacific waters and increase hurricane activity in the western Atlantic.
b
What major factors play a role in global warming? human activity and normal climate conditions natural factors and human activity normal climate conditions and abnormal human activities abnormal human activities and natural factors
b
Which definition best describes global warming? a long-term change in the Earth's climate a long-term increase in the Earth's average temperature a long-term change in the climate of a region or a city solar heat that is radiated out into space
b
Which is a possible result of rising ocean temperatures caused by global warming? formation of dust bowls increase in strength of hurricanes rapid evaporation of water in soil decrease in population due to health threats
b
What are global wind patterns called? La Niña local winds prevailing winds El Niño
c
Which statement best describes the greenhouse effect? It is a process by which plants are able to grow well in a warm, enclosed structure. It is a process by which greenhouse gases block the sun's light to penetrate the atmosphere. It is a process by which greenhouse gases allow the sun's light to penetrate the atmosphere but stop the heat from escaping. It is a process by which prevailing winds bring moisture to the land, to the prevailing wind direction.
c
Which statement explains why many scientists believe that carbon dioxide has likely contributed more to global warming than other greenhouse gases? Carbon dioxide is emitted from fertilizers used in farming. Other greenhouse gases trap more heat than carbon dioxide. Carbon dioxide has increased as a result of increased human activities. Carbon dioxide is emitted from commercial refrigeration.
c
What negative effect occurs when there is a decrease in air quality? faster evaporation of water in the soil the drying out of fertile land, resulting in dust bowls the melting of glaciers and polar ice caps increased illnesses that result in a decrease in population
d
Which greenhouse gas is produced by commercial refrigeration and air conditioning systems? carbon dioxide fluorinated gas nitrous oxide methane
not a
Which is a possible result of higher air temperatures caused by global warming? increase in sea level freezing of polar ice caps rapid evaporation of water in the soil flooding of low-lying coastal areas
not a
Why do some scientists believe that carbon dioxide is responsible for global warming? Check all that apply. Carbon dioxide levels in the Earth's atmosphere have been steadily decreasing. Carbon dioxide levels in the Earth's atmosphere have been steadily increasing. Carbon has a longer average lifetime in the atmosphere. Carbon has a shorter average lifetime in the atmosphere. Other greenhouse gases amplify the effect of carbon dioxide.
not a b
According to some scientists, which is a cause of global warming? decrease of nitrous oxide changes in cloud cover decrease of methane gas changes in solar energy

not b
What climate conditions occur during La Niña? stronger prevailing winds and more hurricane activity warmer Pacific waters and warmer winters more hurricane activity and warmer Pacific waters warmer winters and stronger prevailing winds
not d
Which greenhouse gas has an average lifetime in the atmosphere of a few weeks to thousands of years? carbon dioxide methane nitrous oxide fluorinated gas
not d
