Our Multiple-Choice Quiz will test your knowledge of the basic concepts and ideas offered in Chapter 3. By successfully reviewing these concepts, you will reinforce your comprehension of these geographic ideas.

This activity contains 20 questions.

	Select the most correct statement regarding the stratosphere.   it has no winds it has constant temperature throughout its depth it is below the troposphere it destroys ozone it is warmer at the top than the bottom

	Pressure at a point in the atmosphere reflects   weight of the atmosphere above the point. weight of the atmosphere below the point. total weight of the atmosphere above and below the point. none of the above.

	Most of what we call weather occurs in the   ozonosphere. stratosphere. troposphere. mesosphere. ionosphere.

	The basic distribution of heat (and therefore of temperature) over the Earth is primarily a function of   relative humidity. latitude. the distribution of land and water. the general circulation of the atmosphere. elevation.

	Atmospheric particles (such as dust and ash)   aid in cloud formation. attract water. absorb sunlight. reflect sunlight. do all of the above. do none of the above.

	Of the following gases, which is classified as a variable-amount gas?   argon helium water vapor oxygen neon

	What part of the atmosphere shields Earth's surface from harmful ultraviolet radiation?   troposphere tropopause mesosphere ozonosphere none of the above

	The aurora borealis and aurora australis are caused by an interaction between charged particles and Earth's magnetic field. What layer of Earth's atmosphere contains these particles?   troposphere mesosphere ozonosphere ionosphere stratosphere

	A molecule of ozone gas consists of   one oxygen atom. two oxygen atoms. three oxygen atoms. two oxygen atoms plus one nitrogen. one positively charged ion plus two negatively charged ions.

	What is the atmosphere zone called that is characterized by gases not well mixed, which are layered in accordance with their molecular masses?   troposphere homosphere ozonosphere heterosphere mesosphere

	The layers of the atmosphere are defined by   altitude. temperature. temperature change. their gaseous composition. none of the above.

	Atrmospheric pressure   decreases at an increasing rate through the atmosphere. decreases at a constant rate through the atmosphere. decreases at a decreasing rate through the atmosphere.

	A deep layer of electrically charged molecules and atoms that reflects radio waves is   the heterosphere. the radiosphere. the thermosphere. the ionosphere.

	In terms of the controls of weather and climate, latitude   primarily affects humidity. primarily affects temperature. primarily affects atmospheric circulation. primarily affects precipitation. has no effect.

	The tropopause   varies in height over the year at a particular place. is higher over the poles. is higher near the equator. both (1) and (2) above. both (1) and (3) above.

	Water vapor is considered a variable gas because   the total amount of water vapor in the entire atmosphere varies. the amount of water vapor varies in time. the amount of water vapor varies with location. of all the above. of none of the above.

	Particulates that readily absorb water are described as being   hygroscopic. hydroscopic. hydrophobic. none of the above because they do not absorb water.

	The warm zone of the stratosphere is found near the ___________ of the ozone layer.   top bottom

	Which of the following is/are considered a "thermal layer"?   the troposphere the ionosphere the homosphere the heterosphere all of the above

	Which of the following layers corresponds to the heterosphere?   the troposphere the stratosphere the mesosphere the thermosphere
