My is is big
Because its true our solar system is big
Answer:
They all have the same number of protons but different numbers of neutrons.
Explanation:
These are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.
The atomic number is the number of protons in an atom. For a neutral atom, it is the same as the number of electrons.
The mass number is the number of protons and neutrons in an atom.
silicon-28 (28Si)
silicon-29 (29Si)
silicon-30 (30Si)
All of these isotopes have an atomic number of 16
Now let us chech for the neutrons:
Number of neutrons = mass number - atomic number:
for silicon-28 (28Si) : 28-16 = 12 neutrons
silicon-29 (29Si)
: 29-16 = 13 neutrons
silicon-30 (30Si): 20-16 = 14 neutrons.
First you would melt because the melting point for ice is 0c. Then you would become warmer and warmer as the temperature rises. Lastly once the temperature reaches 100c you'll begin to evaporate as the boiling point for water is 100c.
The currents of the mantle pull the crust above it through drag. The plates, therefore, move on top of the mantle. At San Andreas fault, the North American Plate met the Pacific plate. However, due to the presence of the Farallon plate that was disappearing into the mantle in a subduction zone, the Pacific and North American plates movements changed in their configuration. The two plates now move past each other. The San Andreas fault is, therefore, a strike-slip fault.
I think it's B because it goes up i'm not sure yet but i'll find the answer, but for right now i think it's B
