ASTRONOMY 101 FINAL EXAM QUESTIONS WITH CORRECT ANSWERS 1. What is the main mechanism by which the lower atmosphere of Earth is heated? a. Sunlight heats Earth's surface and the resultant heat is transferred to the atmosphere by infrared radiation and convective gas motions. b. Conduction carries heat from Earth's interior to the surface where conduction in the lower atmosphere transfers this heat to the higher layers. c. friction between the winds in the atmosphere and the mounta...

Tropical cyclones huge, circulating masses of clouds and warm, moist air; zones of low atmospheric pressure that cause air to rise and condense, creating locally intense rainfall. Hurricane Atlantic and East Pacific. Typhoon and Cyclone Western Pacific and Indian Oceans. Formation of a Tropical Cyclone 1) Warm, vapor-rich air rises from the ocean 2) Rising moist air cools, vapor condenses to rain and heats the air 3)Warm evaporating water is the hurricane's fuel 4) Rotates because of Co...
