How are earthquakes related to where mountains are located?
Lesson Objectives...
Develop a model showing what is happening at a scale larger than we can see (patterns) to help explain what happened to the different mountains to (cause) them to change (in elevation and/or location).
Ask questions that arise from our analysis of information showing that Mt. Everest and four other mountain peaks are changing to seek additional information about what caused the changes (effects) we read about.

Colors on a Relief Map - What do they represent?
Colors on a Relief Map - What do they represent?
Colors associated with land vs. liquid water vs. snow/ice
Blue regions- where liquid water is found, but the water has been removed here
Green and brown regions- where land is found
White regions- snow or ice
Elevation changes associated with color variances
Brown variations- darker brown really high up elevation and lighter brown is further down but not quite at sea level
Green variations- green and darker green represent from 1 to a few 100 feet above sea level
White variations- these can also be in some cases between 0 to 10,000s of feet above sea level

What we figured out in this lesson...
What we figured out in this lesson...
- The ground moves back and forth in an earthquake. (Lesson 2)
- Some parts of the surface crack open with a noticeable difference in between the ground on either side of the crack after an earthquake. (Lesson 2)
- Earthquakes exist on or near almost all mountain ranges. (Lesson 2)
- There seems to be a correlation between when mountains were highest or growing and where the earthquakes are the largest or most frequent. (Lesson 2)
- While earthquakes seem to be correlated to changes in elevation, we are not sure what is occurring under the surface. (Lesson 2)
