O Ocean currents create changes in the temperature of air over land masses. O Ocean currents cause the temperature of air over large bodies of water to change.
O Ocean currents move cold water from the equator to the poles, creating cool weather region
O Ocean currents carry warm water from the poles to the equator to create warm weather reg

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
