Review#2 graphs&change Review#2 graphs&change Presentation Transcript

  • L.O: REVIEW GRAPHS ANDCHANGE
  • “A PICTURE IS WORTH ATHOUSAND WORDS”
  • SCIENTISTS USE “PICTURES” IN THE FORMOF GRAPHS AND TABLES TO ORGANIZEOBSERVATIONS.
  • GRAPHS AND TABLES MAKE IT EASIER TOUNDERSTAND THE “STORY” THAT THE DATAIS “TELLING” US!
  • THE EARTH SCIENCE REGENTS HASMANY, MANY, MANY TABLES!
  • A DIRECT RELATIONSHIP GRAPH: ASTHE X-AXIS INCREASES, THE Y-AXISALSO INCREASES.
  • A INVERSE RELATIONSHIP GRAPH: ASTHE X-AXIS INCREASES, THE Y-AXISDECREASES.
  • A NO RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS DOES NOTINCREASE OR DECREASE.
  • A CYCLICAL RELATIONSHIP GRAPH: AS THEX-AXIS INCREASES, THE Y-AXIS INCREASESAND DECREASES OVER AND OVER AGAIN
  • MOST NATURAL PROCESS ARE CYCLICAL(EX. TIDES, THE SEASONS, CELESTIALMOTION OF PLANETS ARE CYCLICAL)
  • I MUST BE ABLE TO READ THEGRAPHS ON THE EARTH SCIENCEREGENTS.
  • Base your answer on The GRAPH below indicates the average number ofdaylight hours and the average surface air temperature over a 12-monthperiod at a specific location on the Earth.

Based on the graph, thehighest average surface air temperature occurs• a. on June 21• b. between June 21and September 23• c. on December 21• d. between December21 and March 21
  • Which statement is best supported bythe graph?• a. The infrared radiation givenoff by the Sun occurs at awavelength of 2,000 angstroms.• b. The maximum intensity ofradiation given off by the Sunoccurs in the visible region.• c. The infrared radiation givenoff by the Sun has a shorterwavelength than ultravioletradiation.• d. The electromagnetic energygiven off by the Sun consists of asingle wavelength.
  • I WILL HAVE TO DRAW AT LEASTONE GRAPH ON THE EARTH SCIENCEREGENTS!
  • ISOLINES (TOPOGRAPHIC MAPS), CONTOURLINES, ISOTHERMS, ISOBARS ARE GRAPHS THAT CONNECTPOINTS WITH EQUAL MEASUREMENTS.
  • I MUST REMEMBER TO “CONNECT THE DOTS”. TO CONNECTTHE SAME MEASURES TO EACH OTHER.
  • Does the map below show isolines, isotherms or isobars?How do you know?
  • Draw the 1024- and 1028-millibar isobars on the weathermap provided below.
  • Remember: isobars are always circular
  • are these HIGH pressure or LOWpressure system? How do you know/
  • Is this an isoline, isobar or isotherm?How do you know?
  • On the field map provided, draw only the15°C and the 20°C isotherms. Isothermsmust be extended to the edge of the map.
  • Remember: I must draw isotherms from theedge of the field map to another edge.
  • Contour maps (topographic maps):connect points of equal elevation(height above sea level)
  • Contour maps (topographic maps): connectpoints of equal elevation (height above sealevel)
  • CONTOUR INTERVAL shows the distance inelevation between two contour lines
  • I must be able to find the contourinterval, if it isn’t given.
  • What is the contour interval of thismap?• a. 10 m• b. 50 m• c. 100m• d. 150m
  • On contour maps, v-shaped linesrepresent a stream (river)
  • The point of the v-shaped lines showwhere a stream (river) comes from.
  • This stream comes from the northwest and flows towards south east.
  • On a contour map, the steepest slope iswhere the contour lines are close together.
  • On a contour map, the gentle slope iswhere the contour lines are far apart.
  • A hole (a depression) is represented byhachure lines
  • A contour profile is “side view” of acontour map. I will have to draw oneon the regents.
  • I will also have to calculate thegradient (the slope) of a contourmap.Turn to page 29 of the greenworkbook.
