Compression.<\/p>\n<p>When air sinks, it is compressed by the air above it. This compression causes the air molecules to move closer together, which increases their temperature.<\/p>\n<p>Option B is incorrect because expansion causes air to cool. When air expands, the air molecules move further apart, which decreases their temperature.<\/p>\n<p>Option C is incorrect because condensation is the process of water vapor in the air turning into liquid water. This process does not cause air to warm.<\/p>\n<p>Option D is incorrect because friction is the force that opposes the relative motion of two objects that are in contact with each other. This force does not cause air to warm.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Compression&#8221; option2=&#8221;Expansion&#8221; option3=&#8221;Condensation&#8221;
