HELP PLEASE! and give out a good explanation! Which of the following form the pattern of surface currents on Earth?
A. high and low tides
B. the Sun's gravitational pull and Earth's rotation
C. global winds and the Coriolis effect
D. the Moon's gravitational pull and Earth's tilt on its axis

C. global winds and the Coriolis effect

Explanation:

Gyres flow clockwise in Northern Hemisphere oceans and counterclockwise in Southern Hemisphere oceans because of the Coriolis Effect. creating surface ocean currents.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
