What was formed when the pacific and north american plates converged? a. the hawaii islands b. the san andreas fault c. mt. saint helens d. the mid-atlantic ridge what has formed as a result of diverging plates? a. the mid-atlantic ridge b. the hawaiian islands c. mt. saint helens d. san andreas fault

There are three kind of tectonic plates movements or interaction which leads to major changes in the structure of earth.

a) Divergent movements: here plates move away from each other leading to formation of rift valley etch. These movements are considered to be constructive in nature

b) Convergent : Here plates move towards each other leading to destruction in the earth.

c) sometimes a little or limited movement of plates (either divergent or convergent) is also observed which is called as transformed movement.

i) When pacific and north american plates converted towards each other they results in formation of San Andreas fault.

Here from the west The Pacific Plate shown movement in northwest direction towards   North American Plate, which is on the eastern side, resulting earthquakes and creation of San Andereas fault

ii) as a result of diverging plats "Mid atlantic Ridge is formed"

Mount St. Helens

Explanation:

I'm in K12 and this is the correct answer

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
