Answer:
The best answer to the question: The greenhouse effect is driven by the fact that greenhouse gases are:___, would be: Good absorbers of radiation at all wavelengths.
Explanation:
Under normal circumstances, the Earth receives energy from the sun and also produces a bit of its own energy. The energy that arrives from the sun is usually known as shortwave radiation, while the energy that is both absorbed by the Earth´s atmosphere, and the energy produced by Earth itself, becomes part of what is known as the longwave radiation. Greenhouse gases, like water vapor, carbon dioxide and methane trap both longwave and shortwave radiation, which should usually be expelled to a certain extent towards space, and maintain them trapped inside the atmosphere. This bouncing effect between the shield created by the gases and the lower atmosphere, should normally be controlled by the amount of atoms of gases in the higher atmosphere. However, in the greenhouse effect, what is happening is that the amount of gases is too high, and therefore they are trapping most of the radiation, both longwave and shortwave, and keeping it in, allowing the climate to warm up.

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.

Answer:
Economic resources of the Rocky Mountains are varied and abundant. Minerals found in the Rocky Mountains include significant deposits of copper, gold, lead, molybdenum, silver, tungsten, and zinc. The Wyoming Basin and several smaller areas contain significant reserves of coal, natural gas, oil shale, and petroleum.
And scientists say it will take natural processes 6,000 years to refill the reservoir
