Question

3 multiple choice 20 points which of the following statements is accurate? the currents in the southern hemisphere are all cold currents the currents in the northern hemisphere are all warm currents the currents in the northern hemisphere flow counter - clockwise the currents in the northern and southern hemispheres flow is opposite directions

Explanation:

1. Analyze Option 1: In the southern hemisphere, there are both warm and cold currents (e.g., the Agulhas Current is warm), so "all cold currents" is wrong.
2. Analyze Option 2: In the northern hemisphere, there are cold currents (e.g., the California Current), so "all warm currents" is wrong.
3. Analyze Option 3: In the northern hemisphere, ocean currents in gyres (like the North Atlantic Gyre) flow clockwise, not counter - clockwise, so this is wrong.
4. Analyze Option 4: Due to the Coriolis effect, ocean currents in the northern hemisphere gyres flow clockwise and in the southern hemisphere gyres (excluding near Antarctica) flow counter - clockwise, so their flow directions are opposite in general gyre circulation.

Answer:

The currents in the northern and southern hemispheres flow is opposite directions (the fourth option)
