L.O: REVIEW GRAPHS AND CHANGE

“A PICTURE IS WORTH A THOUSAND WORDS”

SCIENTISTS USE “PICTURES” IN THE FORM OF GRAPHS AND TABLES TO ORGANIZE OBSERVATIONS.

GRAPHS AND TABLES MAKE IT EASIER TO UNDERSTAND THE “STORY” THAT THE DATA IS “TELLING” US!

THE EARTH SCIENCE REGENTS HAS MANY, MANY, MANY TABLES!

A DIRECT RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS ALSO INCREASES.

A INVERSE RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS DECREASES.

A NO RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS DOES NOT INCREASE OR DECREASE.

A CYCLICAL RELATIONSHIP GRAPH: AS THE X-AXIS INCREASES, THE Y-AXIS INCREASES AND DECREASES OVER AND OVER AGAIN

MOST NATURAL PROCESS ARE CYCLICAL (EX. TIDES, THE SEASONS, CELESTIAL MOTION OF PLANETS ARE CYCLICAL)

I MUST BE ABLE TO READ THE GRAPHS ON THE EARTH SCIENCE REGENTS.

Base your answer on The GRAPH below indicates the average number of daylight hours and the average surface air temperature over a 12-month

period at a specific location on the Earth.Based on the graph, the highest average surface air temperature occurs

• a. on June 21• b.  between June 21

and September 23• c. on December 21

• d. between December 21 and March 21

Which statement is best supported by the graph?

• a. The infrared radiation given off by the Sun occurs at a wavelength of 2,000 angstroms.

• b.  The maximum intensity of radiation given off by the Sun occurs in the visible region.

• c. The infrared radiation given off by the Sun has a shorter wavelength than ultraviolet radiation.

• d. The electromagnetic energy given off by the Sun consists of a single wavelength.

I WILL HAVE TO DRAW AT LEAST ONE GRAPH ON THE EARTH SCIENCE REGENTS!

ISOLINES (TOPOGRAPHIC MAPS), CONTOUR LINES, ISOTHERMS, ISOBARS ARE GRAPHS THAT CONNECT POINTS

WITH EQUAL MEASUREMENTS.

I MUST REMEMBER TO “CONNECT THE DOTS”. TO CONNECT THE 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 weather map provided below.

Remember: isobars are always circular

are these HIGH pressure or LOW pressure system? How do you know/

Is this an isoline, isobar or isotherm? How do you know?

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.

Remember: I must draw isotherms from the edge of the field map to another edge.

Contour maps (topographic maps): connect points of equal elevation (height above sea level)

Contour maps (topographic maps): connect points of equal elevation (height above sea level)

CONTOUR INTERVAL shows the distance in elevation between two contour lines

I must be able to find the contour interval, if it isn’t given.

What is the contour interval of this map?

• a. 10 m• b. 50 m• c. 100

m• d. 150

m

On contour maps, v-shaped lines represent a stream (river)

The point of the v-shaped lines show where a stream (river) comes from.

This stream comes from the north west and flows towards south east.

On a contour map, the steepest slope is where the contour lines are close together.

On a contour map, the gentle slope is where the contour lines are far apart.

A hole (a depression) is represented by hachure lines

A contour profile is “side view” of a contour map. I will have to draw one on the regents.

I will also have to calculate the gradient (the slope) of a contour map.
