<prompt> Hlalosa hore na ke hobaneng ha khatello ea sepakapaka e fokotseha ha bophahamo bo ntse bo eketseha.nan  <response>: Instruction in English: Explain why atmospheric pressure decreases as altitude increases. . Response in English: Atmospheric pressure is the force exerted by the weight of the atmosphere on a given area. This force is caused by the gravitational attraction between the Earth and the molecules that make up the atmosphere. As altitude increases, atmospheric pressure decreases because there is less air and thus fewer molecules above any given point. With less air overhead, the weight of the atmosphere pushing down on that point is less, which translates into less atmospheric pressure. In other words, at higher altitudes, there is simply less stuff i.e., fewer air molecules pushing down from above, and as a result, the pressure exerted by the atmosphere decreases. This is why the atmospheric pressure is lower at the top of a mountain than at sea level. . Response in Sesotho: Khatello ea atmosfere ke matla a sebelisoang ke boima ba sepakapaka sebakeng se itseng. Matla ana a bakoa ke khoheli e teng pakeng tsa Lefatše le limolekhule tse etsang sepakapaka. Ha bophahamo bo ntse bo eketseha, khatello ea sepakapaka ea fokotseha hobane moea o fokola me kahoo limolekhule tse fokolang ka holima ntlha efe kapa efe. Kaha moea o ka holimo o fokola, boima ba sepakapaka se theohelang ntlheng eo bo fokotseha, e leng se etsang hore ho be le khatello e fokolang ea sepakapaka. Ka mantsoe a mang, libakeng tse phahameng, ho na le lintho tse fokolang feela ke hore, limolekhule tse fokolang tsa moea tse theohang holimo, me ka lebaka leo, khatello e hlahisoang ke sepakapaka ea fokotseha. Ke ka lebaka leo khatello ea sepakapaka e leng tlaase tlhōrōng ea thaba ho feta boemong ba leoatle.
