Answer:
Harry Hess was a professor of geology at Princeton and soon became interested in geology of oceans while serving in the navy. He used the opportunity ,of being in the navy, to use echo sounding to map the ocean floor. In 1962, he published "The history of ocean basins" which outlined the theory called 'Sea floor spreading' that explained how continents could drift. He found out that oceans were more shallow in Mid ocean ridges, which were raised above the abyssal plain. He also found out that the deepest parts of the oceans were close to continental margins with trenches in the ocean leading down to depths of over 11 kilometers in the Marianas Trench. Hess believed that ocean trenches were where the ocean floor was recycled after being destroyed.

Answer: A. Air bubbles trapped in a layer indicate how much CO2 was in the atmosphere the year the layer formed.
Explanation:
When ice cores were formed, they included air bubbles that got stuck during the formation. Scientists can study these air bubbles to find out how much carbon dioxide is in them as this will show the proportion of carbon dioxide in air at the time the core was formed.
They can then compare those figures to current carbon dioxide levels to see if there has been a change. This change will give proof of climate change.
