Investigation 2.2 Electronic Field Trip

Pima Point:
Why do some areas of the Grand Canyon have plants growing and other areas do not? Relevant question because it deals with the type of soil and rock formation that would allow plant growth and where the flood line of the Colorado River use to be prior to Glenn Canyon Dam.
Where is the best location to camp in the Grand Canyon? Not relevant because it does not tell us anything about the history of the Earth.
Lines in the cliff walls? Relevant because it has to do with layers of the Earth, what was in the area millions of years ago(covered by water), how the Earth formed over time, and how the river eroded through the rock layers.
Photo Exhibit:
Colors of rock and plant material. Relevant due to formation or Earth and conditions to allow plant growth.
Rock climbers. Relevant that it has to do with the type of rocks formed but not relevant if all we are interested in is the rock climbers.
Picnic. Not relevant (unless you are hungry)
Grand Canyon Rock Samples:
Pretty. Not relevant to formation of the rock
Gray and smooth. Relevant to effects of erosion and classifying rocks.
