Answer: She could research what geologists have already discovered about the canyon.
She could hike into the canyon and make observations of the rocks in each layer.
She could compare her observations of the rock layers to other rock layers in the area.
Answer:
A) Propagation of pressure fluctuations in a medium
B) air is the medium in which the wave is transported,
Explanation:
Part A.
A sound wave is a longitudinal oscillation of the molecules that forms in a material medium, they can be solid, liquid or gases, therefore the wave propagates in the same direction as the oscillation of the particles.
The most correct answer is:
* Propagation of pressure fluctuations in a medium
Part b
air is the medium in which the wave is transported, otherwise it cannot propagate
Answer:
Explanation:
In this problem we can use Bohr's atomic model, to deal with the electronic transition, so we can have transitions between two given states.
ΔE = 
-E₀
Lower state final state energy
Fundamental first excited state ΔE₁ = -2.4 - (-4.7) = 2.3 eV
Fundamental second excited state ΔE₂ = -1.0 - (-4.7) = 3.7 eV
Fundamental third excited state ΔE₃ = -0.3 - (-4.7) = 4.4 eV
As they indicate that there are no electrons in the excited states these are the only possible transitions.
When a wide range of light strikes, the frequencies of these energies are absorbed and observed as black bands (absence of radiation) in the spectrum.

Pull the tabs and wrap around to stick to the front of the diaper:)
Karst topography is created by the chemical weathering process of CARBONATION. Carbonation affects limestone and other carbonate rocks. The action of carbonation creates a distinctive landscape of little surface drainage, sink holes, caves and cockpits.
Rain water mixes with carbon dioxide in the atmosphere to form a weak carbonic acid. The carbonic acid then reacts with the calcium carbonate in the rocks to form a soluble calcium bicarbonate that is easily washed away by water.
