Hi, according to my research the climate in Italy varies depending on which part of Italy. North of Italy the climate is more unpleasant; with freeing & dry winters, & scorching hot/humid summers. Moving to central Italy climate is more in the middle with not as harsh winters & summers. Also central Itally has a shorter duration for winter but the summers are longer. As for the southern portion of Italy seasons are fair, winter is never bad, & spring and autumn are the same as the summer temperatures in the central regions. Let me know if you need me to explain more. Hope this helped :)
The correct answer is letter B. increase deposition of sediments upstream. The negative effect of using too much water for the irrigation of crops is that it wash out sediments and these sediments are brought down the water streams.
Answer:
B
Explanation:
Natural Resource is a source of energy that doesn't need any action from humans. The sun doesn't need the help of humans, therefore it is a natural resource
Answer:
The application of scientific knowledge to solve problems or create new products is inter dependant with curiosity
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.
Hope this Helps!!!
