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...

1. Objects under water appear 60 percent larger than they do on land. ANS true 2. As you descend ANS Colors appear to fade. Reds and oranges are among the first colors to disappear. At 30 m/99 ft, little color remains other than blues, grays, blacks and whites. All of the above. 3. Because sound travels faster under water ANS It is harder to determine the direction from which a sound is coming. 4. Which of the following is/are true? ANS Water conducts heat away from your body 25 times f...

OCE EXAM 3 PRACTICE TEST 2023-2024 Most ocean waves form as a result of: landslides. seismic events. winds blowing across the ocean surface. Earth's rotation. density differences between water layers. - CORRECT ANSWER-winds blowing across the ocean surface. The movement of air across the ocean surface creates ________ waves. tidal ocean splash turbidity atmospheric - CORRECT ANSWER-ocean The movement of sea water at a pynocline creates ________ waves. turbidity internal tidal ...

Earth Environmental Science Exam (Answered) Complete Solution Divergent Boundary Place where two of Earth's tectonic plates are moving apart. Epicenter Point on Earth's surface directly above the focus of a earthquake. Magnitude Measure of the energy released during an earthquake, which can be described using the Richter scale. Fault Crack in Earth's crust that occurs when stress is applied. Sea floor Spreading Hess's theory that new ocean crust is formed at mid-ocean ridges sei...

Age of Earth 4.6 billion years Seismometer Instrument used to measure horizontal or vertical motion during an earthquake. Uniformitarianism The past geological events can be explained by forces occurring today Alfred Wegener A German scientist who proposed the theroy of continental drift Geologic evidence of continental drift -rock units on different continents have similar structure Mid Ocean Ridges -submerged mountain regions -longest continuous feature of the earths crust -tensio...

Recurrence intervals: - answerTime span (in years) until today over which these combined events took place / number of events that meet the criterion (geographical area and minimum magnitude, for example) -ex: 50 years / 10 ear...

ATSC 113 Final Study (2022/2023) Already Passed Three main factors affecting wave formation: Wind velocity, fetch, duration. Wind velocity: Speed of the wind. Fetch: Distance over water wind can blow uninterrupted. Duration: Amount of time wind blows over water. If wind speed is slow, waves will always be _________, regardless of fetch or duration. Slow Drag: Frictional force acting against relative motion of one fluid with respect to another fluid. Describe drag between ocean and air. Tex...

seismic waves - Answer-Vibrations that travel through Earth carrying the energy released during an earthquake. crust - Answer-the outer layer of the Earth mantle - Answer-the layer of hot, solid material between Earth's crust and core lithosphere - Answer-the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle asthenosphere - Answer-the soft layer of the mantle on which the lithosphere floats basalt - Answer-a rock that makes up much ...
