Exam 20: World Climates and Global Climate Change

Climatic zones are often based on different types of vegetation that result from the prevailing climatic conditions. Considering such zones, what are some of the potential problems when using fossil plant assemblages to interpret ancient climates? What are some of the factors geological or otherwise. that would influence your conclusions?

The boundaries of the Köppen climates are largely based on the limits of certain ___________ associations.

The___________ climate is located on the eastern sides of continents, in the 25- to 40- degree latitude range.

Consequences of global warming are___________.

Records indicate that sea level has___________ since 1870.

The magnitude of a temperature increase due to greenhouse warming will probably be smallest in the ___________.

How has loss of ice led to an increase in global warming?

The overall effect of aerosols is to___________ .

Winterless climates with all months having a mean temperature above 18°C are called___________ climates.

The leeward sides of mountains are typically dry enough to be referred to as ___________.

Compared to places at lower elevations, highland climates are usually cooler and ___________ .

The humid subtropical climate dominates the ___________United States.

The tundra climate is a ___________found almost exclusively in the Hemisphere.

Humid continental climates are found between about___________ north latitude
