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.
Answer:
Less dense near the capital.
continues to spread globally, with supply chain disruptions resulting in declines in income and employment. There are, hence, additional worries that the disease could threaten food chains and supply systems and stoke inflation. Water tariffs are also at risk if utilities are not supported financially to contain production costs and keep revenue streams. The Economist magazine recently invoked that notion by stating that shutters businesses and leaves supermarket shelves bare, economists fret that the pandemic could lead to inflation making an unwelcome return.” Thus, we should take a look at how inflation and water tariffs have evolved in years to be able to foresee
