Input: Read this: In 1951, during the early stages of the Cold War, Menzies spoke of the possibility of a looming third world war. The Menzies Government entered Australia's first formal military alliance outside of the British Commonwealth with the signing of the ANZUS Treaty between Australia, New Zealand and the United States in San Francisco in 1951. External Affairs Minister Percy Spender had put forward the proposal to work along similar lines to the NATO Alliance. The Treaty declared that any attack on one of the three parties in the Pacific area would be viewed as a threat to each, and that the common danger would be met in accordance with each nation's constitutional processes. In 1954 the Menzies Government signed the South East Asia Collective Defence Treaty (SEATO) as a South East Asian counterpart to NATO. That same year, Soviet diplomat Vladimir Petrov and his wife defected from the Soviet embassy in Canberra, revealing evidence of Russian spying activities; Menzies called a Royal Commission to investigate.

Input: Read this: By 26 March, the growing refusal of soldiers to fire into the largely nonviolent protesting crowds turned into a full-scale tumult, and resulted into thousands of soldiers putting down their arms and joining the pro-democracy movement. That afternoon, Lieutenant Colonel Amadou Toumani Toure announced on the radio that he had arrested the dictatorial president, Moussa Traore. As a consequence, opposition parties were legalized and a national congress of civil and political groups met to draft a new democratic constitution to be approved by a national referendum.

Input: Read this: The community was established by several shiploads of settlers from Bermuda (which lies due east of South Carolina, although at 1,030 km or 640 mi, it is closest to Cape Hatteras, North Carolina), under the leadership of governor William Sayle, on the west bank of the Ashley River, a few miles northwest of the present-day city center. It was soon predicted by the Earl of Shaftesbury, one of the Lords Proprietors, to become a "great port towne", a destiny the city quickly fulfilled. In 1680, the settlement was moved east of the Ashley River to the peninsula between the Ashley and Cooper Rivers. Not only was this location more defensible, but it also offered access to a fine natural harbor.

Input: Read this: The Alps are a classic example of what happens when a temperate area at lower altitude gives way to higher-elevation terrain. Elevations around the world that have cold climates similar to those of the polar regions have been called Alpine. A rise from sea level into the upper regions of the atmosphere causes the temperature to decrease (see adiabatic lapse rate). The effect of mountain chains on prevailing winds is to carry warm air belonging to the lower region into an upper zone, where it expands in volume at the cost of a proportionate loss of temperature, often accompanied by precipitation in the form of snow or rain. The height of the Alps is sufficient to divide the weather patterns in Europe into a wet north and a dry south because moisture is sucked from the air as it flows over the high peaks.
Question: What causes the temperature to decrease?

Output:
A rise from sea level into the upper regions of the atmosphere
