True or False

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

This activity contains 14 questions.

	Water is the most common compound on the Earth's surface.    True  False

	Worldwide changes in sea level are called outgassing.    True  False

	The sum of ice sheets, glaciers, and subsurface groundwater accounts for more than 99 percent of Earth's freshwater.    True  False

	Lake Baykal, located in Siberian Russia, is the single largest body of freshwater on Earth.    True  False

	The transition from liquid water to ice or ice to liquid water is called sublimation.    True  False

	The water vapor content of air is called humidity.    True  False

	The temperature at which air achieves saturation is called the sublimation temperature.    True  False

	The dry adiabatic rate (DAR) is the rate at which an expanding, unsaturated parcel of dry air cools.    True  False

	Air is saturated if it contains all of the water vapor that it can hold at a given temperature. This is also when the relative humidity reaches 100 percent.    True  False

	The eight-sided appearance of ice crystals (e.g. snowflakes) reflects the structure of water molecules and the way they are arranged when water takes a solid form.    True  False

	Water's "wetness," and many of its other important properties, are the result of the polarity of water molecules.    True  False

	Assuming no change in the actual amount of water vapor in the air, as air temperature rises, relative humidity decreases.    True  False

	The difference between the dry adiabatic rate and the moist adiabatic rate is due to the release of latent heat as water vapor condenses.    True  False

	The moisture droplets in clouds average about 300 micrometers in diameter.    True  False
