Answer and Explanation:

About two-thirds of the Earth's surface lies beneath the oceans. The depths of the open ocean were mostly a matter of speculation before the 19th century. Most people thought ocean floor was flat and featureless. In the early 16th century, a few navigators found that the open ocean can differ considerably in depth by taking soundings with hand lines, which shows that the ocean floor was not as flat as it believed.

At the beginning of the 1950s, scientists used magnetic instruments adapted from airborne devices to recognize odd magnetic variations across the ocean developed during World War II to detect submarines. They found that the iron-rich and volcanic rock make up the ocean floor-- contains a strongly magnetic mineral and can distort compass readings. In the early 18th century, this distortion was recognized by Icelandic mariners. Magnetite gives measurable magnetic properties; these magnetic variations help to study the deep ocean floor.

The northern hemisphere has a slightly greater 0.041% CO2 content in the air. The difference between the seasons is this. The northern hemisphere, which has the most population, industry, transportation, and nearly all deciduous trees, contains the majority of the Earth's landmass.

Therefore, as leaves start to grow in the spring, they absorb CO2 from the atmosphere, slightly lowering the concentration. Additionally, people use less heating in their homes and buildings, which lowers CO2 emissions .Because the southern hemisphere's large population centers, like Brazil, are primarily tropical, there is less heating in homes there. The same is true for most of Australia and some African nations. Trees and other plants are mostly evergreen due to the region's predominantly tropical and subtropical climate. For instance, Tasmania is home to the sole native deciduous tree of Australia. As a result, the southern hemisphere's carbon dioxide concentration, which is roughly 0.0400%, is slightly lower and less variable.
