1. Analyze Graph
What is the title? (Create a title for each graph which mentions the variable(s) being measured and the relationship shown.
What is on the X & Y Axes?
What trend is shown by the data points, best-fit line or graphic? (As the independent variable changes, how does that affect the dependent variable? This tells you the relationship between the variables)
What units are the data given in?
What additional facts do you know or are given about this information?
What predictions can be made using this information? (Use the information any way you like to predict anything from animal migratory patterns to best types of clothing to sell. You must be able to support your prediction with the data you used to make it.

2. Analyze Graph Temperature Low Temp to High Temp 0° Latitude 90°
Relationship between average temperature and latitude
Latitude is on the X and Temperature is on the Y
The trend is that the temperature decreases as latitude increases. (As you travel from the equator toward the poles.)
Units are degrees
Temperature is higher at the equator and lower at the poles due to unequal heating of the earth caused by it’s spherical shape, tilt, and the angle of sunlight hitting the surface where measured.
You can predict that the average temperature of cities located on land around the 45 degree latitude line will receive approximately half the direct sunlight as compared to cities located on land around the equator.

3. Analyze Graph
The slide shows that coastal cities are cooler than inland cities and that their temps are in a shorter range.
The air is cooler (and wetter) on the windward side of the mountains close to the shore and warmer (drier) down the leeward side in the valley.
=======================================================================================
Relationship between proximity to water and average temperature
There are no X & Y axes.
The trend shown in the graphic is that coastal cities have a lower average temperature compared to inland cities.
Units for temperature are given in degrees F.
This is California in the USA which is located between N latitude in the Prevailing Westerlies. The coastal cities will receive more precipitation than the inland cities.
Based on the prevailing winds and latitude, Santa Barbara should experience more precipitation in the form of rain than Bakersfield and neither will receive much annual snowfall. Crescent City should experience more precipitation compared to Redding and will receive more annual snowfall than any other city shown on the map.

Analyze Graph
The figure shows temperature (red line) and precipitation (blue bars) information over a 1-year period for 2 different locations.
Double X and Y axes!
The location on the left is much closer to a body of water, so its temperature is more regulated and it experiences greater annual precipitation compared to its inland counterpart.
A contributing factor to this data might also be altitude. The location on the left was measured at 6m elevation and the location on the right at 103m.
===============================================================================
Annual Average Precipitation & Temperature in Reykjavik, Iceland and Yakutsk, Russia
Time in months is on the X and there is a double Y axis. Temperature in degrees C is indicated on the left and tracks the red line. Precipitation is indicated on the right measured in cm and tracks the blue bars.
Both locations are in the Polar Easterlies located above 60N latitude. Both locations have very cold annual temperatures. Reykjavik is a coastal city and Yakutsk is an inland city.
With higher annual snowfall coming mainly from the East, a safer spot to build a marina would be on the West coast of Reykjavik.

5. Analyze Graph Annual Average Monthly Temperature of City A & City B
Time in months is on the X and Average Monthly Temp is on the Y
There are 2 different trends on the graph. City A has a more wildly fluctuating annual temperature profile while City B has a more regulated annual temperature profile.
The unit of time is months and the unit for temperature is degrees C.
City A has an annual temperature range of between -3 and 25 degrees C while City B has an annual temperature range between 9 and 13 degrees C.
With a much more regulated annual temperature profile, City B is probably a coastal city and City A is most likely an inland city.

6. We live in the troposphere.
Analyze Graph
We live in the troposphere.
Atmospheric Layer Temperature Trends
Temperature in degrees C is on the X and Altitude in km and mi are on the Y.
There is no clear trend throughout the data. Each layer’s trend must be identified separately. The troposphere and mesosphere have a decreasing temperature profile with altitude and the stratosphere and thermosphere have an increasing temperature profile with altitude.
As altitude increases air density and pressure decrease.
Using this information as a guide, one can predict that areas between the layers have stable temperatures.

7. Analyze Graph Temperature Low Temp to High Temp Elevation
Relationship between elevation and temperature
Elevation is on the X and Temperature is on the Y
The trend is that as elevation increases temperature decreases.
Units are not given. Only a general trend is identified.
High elevation areas have fewer air molecules that are being heated by the reradiated heat from the earth. The chances that those molecules contact each other to exchange heat diminish with altitude.
There will be less air turbulence but be cooler and require more thrust and lift as elevation increases.
Low Elevation to High Elevation

8. This figure shows temperature differences in high elevation located in the northern and western regions of Alaska.
===========================================================================
Alaska’s Monthly Mean July Temperatures by Elevation
There are no X & Y axes here.
The trend is that as elevation increases, temperature decreases.
Temperature is given in degrees C & F. Altitude is given in km and mi.
Alaska is in the 60-90N latitude area on earth where the polar easterlies blow.
During the summer, people from the mountains use more fuel to heat their homes than people from the plains.
During summer, temperature is strongly controlled by elevation -- cold at the higher reaches of the Alaska and Brooks Ranges, and warmer in the lowlands.

9. Air Temp Water Temp Annual Surface and Water Temperatures from 2001
On the upper graph the X axis has longitude and Y has latitude. On the lower graph there are no X & Y axes.
The trend is that air temperature is influenced by water temperature since water takes longer to heat and release heat than air does. Another trend is that the warm air/water is near the equator and gets colder as you approach the poles.
Latitude & Longitude are given in degrees and Temp is given in degrees C.
Most of the direct sun earth receives hits near the equator and indirectly near the poles. Water heats/cools slower than air.
If global warming causes ice sheets to melt into the ocean, than the ocean temperatures will lower the air temperatures and the earth will enter a period of global cooling.
