Because fluid flows from an area of high to low pressure, the drink moves up the straw and into your mouth. When you breathe, a muscle called the diaphragm causes the rib cage and lungs to expand or contract. When they expand, the air in the lungs is under less pressure than the air outside the body, so air flows into the lungs. When the ribs and lungs contract, air in the lungs is under greater pressure than air outside the body, so air flows out of the lungs. | 0.32253 |

NDQ_016137 | air pressure changes with altitude because of changes in | null | a. density of the atmosphere., b. depth of the atmosphere., c. temperature of the atmosphere., d. two of the above | d | T_1755 | text | null | The property that changes most strikingly with altitude is air temperature. Unlike the change in pressure and density, which decrease with altitude, changes in air temperature are not regular. A change in temperature with distance is called a temperature gradient. | 0.728535 |

Why? The stratosphere gets most of its heat from the Sun. Therefore, its warmer closer to the Sun. The air at the bottom of the stratosphere is cold. The cold air is dense, so it doesnt rise. As a result, there is little mixing of air in this layer. | 0.703706 |

Rain is common in low pressure regions due to rising air. Air sinking in high pressure areas causes evaporation; these regions are usually dry. These features have a great deal of influence on climate. | 0.661063 |

When an air mass moves over a new region, it shares its temperature and humidity with that region. So the temperature and humidity of a particular location depends partly on the characteristics of the air mass that sits over it. | 0.654881 |

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. As we breathe, oxygen enters the nose or mouth and passes the sinuses, which are hollow spaces in the skull. Sinuses help regulate the temperature and humidity of the air we breathe. The trachea, also called the windpipe, filters the air that is inhaled, according to the American Lung Association. It branches into the bronchi, which are two tubes that carry air into each lung. The bronchial tubes are lined with tiny hairs called cilia. Cilia move back and forth, carrying mucus up and out. Mucus, a sticky fluid, collects dust, germs and other matter that has invaded the lungs. We expel mucus when we sneeze, cough, spit or swallow. | 0.242626 |

Convection is the transfer of heat from one place to another by the movement of fluids. The heat source lies at the bottom of the diagram. The heat generated by this source causes the air next to it, to warm up. Warm air is lighter than cool air, and hence it rises up. As it rises up, it moves away from the heat source and cools down. As it cools down, it gets heavier and sinks towards the heat source. This cycle continues and causes a convection current. | 0.303114 |
