Answer: there are three different methods of determining the age of a landform.
1 radiation measurement
2 stratigraphic superposition
3 the fossil record
by using these or a combination of these they determined that the earth is around 4.6 billion years old. and this is where the big bang theory comes into play.
Metals usually melt when forming iron
Answer: Yes, if there are more shells the nuclear charge decreases.
Well knowing the number of protons, you can find what the element is, which is Ti = titanium. Then to find the charge, simply subtract 22 and 18 which is +3.
Find the mass number by adding 22 and 34 = 56.
56. +3
Ti
22
This would be the correct notation in isotopic form.
Answer:
C
Explanation:
A - Crude oil is composed for hundreds of hydrocarbon, not less than ten.
B - Is formed in specific conditions of temperature and pressure
C - It's fractionated to form gasoline, lubricants, CH4, plastics and many other products made of hydrocarbon.
D - We have crude oil located more than 4000 yards below the surface in countries like Brazil
E - The crude oil is very thick and don't have an specific usage, so we need to refine it.
