Review for Semester Final Exam Day 4 Items

52 Define the following shoreline features: spit - a ridge of sand projecting into a bay and often having a hooked end. groin – a structure built perpendicular to a beach out into the water and designed to prevent or retard shoreline erosion tombolo - a sand ridge connecting an island to the mainland or to another island seawall - a structure built parallel behind a beach and designed to prevent or retard shoreline erosion

53 Describe the process of “beach nourishment.” replacing lost sand on a beach and designed to prevent or retard shoreline erosion

54 Define the term “weather.” the atmospheric conditions in a given area over a short period of time

55 Define the term “climate.” a description of the general atmospheric conditions based on observations that have been accumulated over many years

56 Classify each of the following as either weather events or climate descriptions: polar - climate humid tropical - climate air pressure - weather wind - weather humid subtropical with mild winters - climate humidity - weather humid subtropical with severe winters - climate clouds - weather precipitation - weather dry - climate air temperature - weather

57 List some aspects of our lives that weather influences. health and comfort the economy jobs everyday activities

58 List some similarities and some differences between weather and climate. both weather and climate can be wet, dry, hot, or cold weather is a short-term summary of atmospheric conditions, whereas climate is accumulated weather data over a long period of time “Climate is what you expect, but weather is what you get."

59 List the three most abundant gas components of our atmosphere. nitrogen oxygen argon

60 Identify the four vertical layers of the atmosphere based on temperature, from bottom to top. troposphere stratosphere mesosphere thermosphere

61 Compare the journey of light rays striking the poles at a low angle to those of rays striking Earth at the equator. Rays of light striking the poles at a low angle travel through more of the atmosphere as the rays at the equator.

62 Denote the longest and shortest days (of sunlight) in the Northern Hemisphere. What are these days called? In the Northern Hemisphere, the longest day occurs during the June Solstice, while the shortest day is the December Solstice.

63 What causes seasonal variations on Earth? Seasonal variations on Earth are caused by: Earth's tilted axis the position of the Sun's vertical rays the length of daylight the variations in the Sun's angle.

64 List the three mechanisms of heat transfer and give an example of each. Conduction is the transfer of heat through solid objects, like getting burned by touching a hot pan’s handle. Convection is the transfer of heat through liquids or gases, like a furnace on one side of a room warming the other side. Radiation is the transfer of heat through empty space, like the Sun warming the Earth from 93 million miles away.

65 What causes the red and orange colors of sunset and sunrise? The red and orange colors of sunset and sunrise are the result of dust in the atmosphere.

66 In what general location on Earth will the annual temperature range be the greatest? The annual temperature range will be greatest for a place located in the interior of a continent.

67 The heating of the atmosphere is explained by what process? The heating of the atmosphere is explained by the Greenhouse Effect.
