L.O: REVIEW GRAPHS AND CHANGE
![Page 2: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/2.jpg)
“A PICTURE IS WORTH A THOUSAND WORDS”
![Page 3: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/3.jpg)
SCIENTISTS USE “PICTURES” IN THE FORM OF GRAPHS AND TABLES TO ORGANIZE OBSERVATIONS.
![Page 4: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/4.jpg)
GRAPHS AND TABLES MAKE IT EASIER TO UNDERSTAND THE “STORY” THAT THE DATA IS “TELLING” US!
![Page 5: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/5.jpg)
THE EARTH SCIENCE REGENTS HAS MANY, MANY, MANY TABLES!

A DIRECT RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS ALSO INCREASES.
![Page 7: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/7.jpg)
A INVERSE RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS DECREASES.
![Page 8: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/8.jpg)
A NO RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS DOES NOT INCREASE OR DECREASE.
![Page 9: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/9.jpg)
A CYCLICAL RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS INCREASES AND DECREASES OVER AND OVER AGAIN
![Page 10: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/10.jpg)
MOST NATURAL PROCESS ARE CYCLICAL (EX. TIDES, THE SEASONS, CELESTIAL MOTION OF PLANETS ARE CYCLICAL)
![Page 11: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/11.jpg)
I MUST BE ABLE TO READ THE GRAPHS ON THE EARTH SCIENCE REGENTS.
![Page 12: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/12.jpg)
Base your answer on The GRAPH below indicates the average number of daylight hours and the average surface air temperature over a 12-month

• a. on June 21• b. between June 21
and September 23• c. on December 21
• d. between December 21 and March 21
![Page 13: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/13.jpg)

I WILL HAVE TO DRAW AT LEAST ONE GRAPH ON THE EARTH SCIENCE REGENTS!
![Page 15: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/15.jpg)
ISOLINES (TOPOGRAPHIC MAPS), CONTOUR LINES, ISOTHERMS, ISOBARS ARE GRAPHS THAT CONNECT POINTS
WITH EQUAL MEASUREMENTS.
![Page 16: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/16.jpg)
I MUST REMEMBER TO “CONNECT THE DOTS”. TO CONNECT THE SAME MEASURES TO EACH OTHER.
![Page 17: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/17.jpg)
Does the map below show isolines, isotherms or isobars? How do you know?
![Page 18: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/18.jpg)
Draw the 1024- and 1028-millibar isobars on the weather map provided below.
![Page 19: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/19.jpg)
Remember: isobars are always circular
![Page 20: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/20.jpg)
are these HIGH pressure or LOW pressure system? How do you know/
![Page 21: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/21.jpg)
Is this an isoline, isobar or isotherm? How do you know?
![Page 22: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/22.jpg)
On the field map provided, draw only the 15°C and the 20°C isotherms. Isotherms
must be extended to the edge of the map.
![Page 23: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/23.jpg)
Remember: I must draw isotherms from the edge of the field map to another edge.

![Page 25: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/25.jpg)
![Page 26: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/26.jpg)
Contour maps (topographic maps): connect points of equal elevation (height above sea level)
![Page 27: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/27.jpg)
Contour maps (topographic maps): connect points of equal elevation (height above sea level)
![Page 28: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/28.jpg)
CONTOUR INTERVAL shows the distance in elevation between two contour lines
![Page 29: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/29.jpg)
I must be able to find the contour interval, if it isn’t given.
![Page 30: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/30.jpg)
What is the contour interval of this map?
• a. 10 m• b. 50 m• c. 100
m• d. 150
m
![Page 31: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/31.jpg)
On contour maps, v-shaped lines represent a stream (river)
![Page 32: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/32.jpg)
The point of the v-shaped lines show where a stream (river) comes from.
![Page 33: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/33.jpg)
This stream comes from the north west and flows towards south east.
![Page 34: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/34.jpg)
On a contour map, the steepest slope is where the contour lines are close together.
![Page 35: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/35.jpg)
On a contour map, the gentle slope is where the contour lines are far apart.
![Page 36: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/36.jpg)
A hole (a depression) is represented by hachure lines
![Page 37: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/37.jpg)
A contour profile is “side view” of a contour map. I will have to draw one on the regents.
![Page 38: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/38.jpg)
![Page 39: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/39.jpg)
![Page 40: Review#2 graphs&change](https://reader036.vdocuments.mx/reader036/viewer/2022062708/558b9a8ed8b42a3b188b458b/html5/thumbnails/40.jpg)
I will also have to calculate the gradient (the slope) of a contour map.
