question
The ________ climate is located on the eastern sides of continents, in the 25- to 40-degree latitude range.
answer
humid subtropical
question
Coastal Alaska and Norway are in the ________ group of climates.
answer
humid middle-latitude, mild winters
question
The wet tropics are limited to areas ________.
answer
below 1000 meters of elevation
question
In the past approximately 100 years, global temperatures have ________.
answer
increased by nearly 1°C
question
The humid subtropical climate dominates the ________ United States.
answer
Southeastern
question
Earth's low-latitude deserts and steppes coincide with the ________ pressure belts.
answer
subtropical high
question
If sea ice melts, this would affect the climate by ________.
answer
increasing the amount of solar energy absorbed at the surface
question
The subarctic climate is often referred to as ________.
answer
the taiga climate
question
Af and Am climates form a discontinuous belt astride the ________.
answer
Equator
question
The ________ sides of mountains are often wet.
answer
Windward
question
Summarize the characteristics associated with highland climates.
answer
Highland (H) - the most obvious climate characteristic thatis altered in these climates is temperature. Annual and monthly temperatures are lower because of adiabatic cooling, and due to the fact that the atmosphere at high altitudes contains less moisture. A drier atmosphere decreases the amount of heat energy that can be generated by surface absorption of longwave counter-radiation from the atmosphere.
question
The climate in which temperatures average 25˚C or more each month and total precipitation for the year is high is the ________ climate.
answer
wet tropics
question
Sea level change is ________.
answer
Accelerating
question
Winterless climates with all months having a mean temperature above 18˚C are known as ________ climates.
answer
humid tropical
question
The major difference in vegetation between the different humid tropical (A) regions is that ________.
answer
wet tropical regions have rain forests, and tropical wet and dry regions have grasslands
question
Compared to places at lower elevations, highland climates are usually cooler and ________.
answer
wetter
question
Which one of the following is NOT a trace gas contributing to a future global increase in temperature?
answer
water vapor
question
Describe at least 3 different possible consequences of global warming.
answer
Sea level rise: Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century. Global temperature rise: All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. Even though the 2000s witnessed a solar output decline resulting in an unusually deep solar minimum in 2007-2009, surface temperatures continue to increase. Warming oceans: The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969.
