which hemisphere of the earth contains the greater proportion of ocean surface?

To find out which hemisphere of the Earth contains a greater proportion of ocean surface, you can follow these steps:

1. Obtain a map or a globe of the Earth to visualize the hemispheres.
2. Identify the equator, which divides the Earth into northern and southern hemispheres.
3. Find the percentage of the Earth's surface covered by each hemisphere. Take note that the Earth is approximately 70% water, with the majority being in the Southern Hemisphere.
 
Given these steps, upon analyzing the globe, you will notice that the Southern Hemisphere contains a larger proportion of the Earth's ocean surface compared to the Northern Hemisphere.

Please note that the exact percentage may vary based on the source and method of calculation.
