Answer:
upper portion (6000ft - 6500 ft)
Explanation:
From the information given:
This activity involves exploring the Zion National Park geology. To achieve this, we need to download the Zion file & open it in Gougle Earth. This is followed by setting the vertical exaggeration to 0.5 & the measurement to feet/miles. The perspective view is also changed to a map view. Now, as viewed in Gougle Earth, the upper portion which is white in nature appears to be steeper than the lower portions. To the Toquerville, the area towards it is remarkably flat with slight undulations.
Answer:
D

Answer:
The age of the rock = 2800.6 million years = 2.8 billion years.
A simple method of analysis similar to Carbon dating is used to obtain the required age of the rock. Radioactive substances decay according to first order reaction kinetics. So, plugging all the required parameters into the general equation for amount of substance left in a first order decay gives us the age of the rock.
Explanation:
Half life of Uranium-235 = 700 million years (from literature)
The decay of radioactive substances follow first order reaction kinetics.
The general equation is given as
A(t) = A₀ e⁻ᵏᵗ
A(t) = Amount of radioactive substance left after a particular time = 6.25%
A₀ = initial amount of radioactive substance = 100%
t = time that has passed since the beginning = age of the rock = ?
k = decay constant
The decay constant is related to the half life (T) through the relation,
k = (In 2)/T
k = (0.693/700) = 0.00099 /million years
A(t) = A₀ e⁻ᵏᵗ
6.25 = 100 e⁻ᵏᵗ
0.0625 = e⁻ᵏᵗ
In e⁻ᵏᵗ = In 0.0625 = -2.7726
-kt = - 2.7726
t = (2.7726/0.00099) = 2800.6 million years
t = 2.8 billion years.
