True or False
Based on the information in the chapter, determine whether each of these statements is true or false.

This activity contains 12 questions.

	Altitude is the single most important influence on temperature variations.    True  False

	Within the troposphere, temperatures decrease with increasing altitude above Earth's surface.    True  False

	Approximately 84 percent of all evaporation on Earth is from the land.    True  False

	Mixing spreads available energy over a greater volume. Thus, the oceans have more evenly spread surface temperatures than do the continents.    True  False

	Locations near the centers of continents are described as having more "maritime" influences than are locations near the coasts.    True  False

	On average, the coldest region of Earth is in northern Canada.    True  False

	Apparent temperature is the perception of temperature, and it varies among individuals and cultures.    True  False

	The coldest wind-chill factors are produced by low temperatures and high winds.    True  False

	The heat index is a combination of temperature and humidity.    True  False

	In July, isotherms in the northern hemisphere shift toward the poles over land since higher temperatures occur in continental interiors.    True  False

	Compared to a land surface exposed to the same solar radiation, an ocean surface should have a higher annual temperature range.    True  False

	A traveler heading due east from San Francisco, CA in January will generally experience warmer overall temperatures as he/she approaches the interior of the continent.    True  False
