This is where we see "falling stars" meteors that fall to the Earth and burn up the atmosphere Thermosphere - Correct Answer-temperature continues to increase with the altitude, with recorded temperatures reaching as high as 2,000 C as its upper limits which extends to several thousan kilmeters above the Earth Warm Front - Correct Answer-When a warm air mass overtakes a cold air mass As the warm air advances it rides ove the cold air ahead of it, which is heavier. As the warm air rises the water vapor in it condences into clouds that can produce rain snow leet or freezing rain - often all four Cold Front - Correct Answer-When a cold air mass overtakes a warm ar mass. Most cold fronts are precceded by a line of precpiptation as they roar across an area. Can produce very little or no precipitation as they move. Stationary Front - Correct Answer-Sometimes two air masses meet and neither is displaced. Instead the two fronts push against each other in a stalement. Stationary fronts often cause cloudy, wet weather that can last a week or more Stratus Clouds - Correct Answer-low-hanging, broad, flat clouse that blanket the sky. The lowest of low clouds. Can cause fog. Dark stratus clouds indicate that rain will soon occure Cumulus Clouds - Correct Answer-are massive clouds that are puffy like popcorns with relatively flat bottoms and rounded tops.

Inline fource cylinder engines are very popular in front - wheel dive cars with transverse (sideways) mounted engines. Most often found in small - to medium - sized vehicles Horizontally opposed or flat desing - Correct Answer-has all of the cylinders lying on the horizontal plane, with half of the cylinders facing away from the other hald and the crankshaft located between them. Camshaft location - Correct Answer-The camshaft is responsible for the pening and closing of the engines valves, and it is driven by the crankshaft through a timing chain or timing belt. ` Firing Order - Correct Answer-The order that the cylinders fire A common firing order for four-cylinder engines is - Correct Answer-1-3-4-2 Firing order of a V-8 engines is - Correct Answer-1-8-4-3-6-5-7-2 Disel engines are simple because - Correct Answer-they do not incorporate a sparl- ignition system also that a disel engine and most gasoline engines is that diesels inject their fuel directly into the combustion chamber Stoichimometric - Correct Answer-The ideal ratio of air to fuel, it is the responsibility of the engines fuel system to maintain that balance Air-Fuel Ratio - Correct Answer-a comparison of the weight of the air relative to the weight of the fuel that has been mixed with it. Is ideal air-Fuel ratio is 14.7: 1 Atomized - Correct Answer-When fuel is mixed with air by the fuel system, The fuel is directed into the air stream that is entering the engine Lean Mixtures - Correct Answer-When too much ait and not enough fuel would be described. Burn relatively slowly because there is greater space between the fuel molecules and it takes more tim for a flame to jump from particle to particles. Burn much hotter and thus can cause serious engine damage.
