Let's start from the beginning.
<span>Millions and millions of years ago, planet Earth was absolutely crowded with volcanoes. </span>
<span>As you may know, volcanoes release steam and gasses. </span>
<span>As the years went by, the gasses released from volcanoes formed the atmosphere around the planet, which prevented the steam from disappearing into outer space. </span>
<span>The steam eventually, in cycles, began to fall back to Earth. Viola, rain had just been "invented". </span>
<span>As more and more rain fell, considering almost every surface of the planet was volcanic, the water began to build up and "flood" the planet. Many active volcanoes had now been transformed into underwater volcanoes. </span>
<span>As more and more years went by, eventually, bacteria in the water slowly began to evolve, first into jelly-fish like creatures, then tadpole-like creatures, leading all the way up to large ferocious underwater reptiles, amphibians and fish. </span>
<span>As the planet started to warm up, probably by methane gasses released from the prehistoric underwater creatures, the water levels on Earth began to drop again. At the same time, the active underwater volcanoes were creating new landmasses, either by lava cooling on the surface of the water or tectonic plates pushing the volcano above sea level. </span>
<span>So, this, is how fossils of sea creatures ended up in high land-based mountains. </span>
<span>Because millions of years ago, most of Earth was underwater until the water levels dropped or lands "grew" higher. </span>
<span>The Rocky Mountains were once underwater. </span>
<span>If you take a look at images of the Grand Canyon in the United States, you'll see that it resembles the deep caverns and canyons that you find at the bottom of oceans. </span>
<span>That's because the Grand Canyon WAS at the bottom of an ocean.</span>
Answer:
The rocks at the bottom of the ocean are younger than the rocks on the continent. This can be pessible due to the process called Continental Drift.
Explanation:
For a long time the human being wondered what would be the age relationship between the rocks at the bottom of the ocean and the rocks of the continent. Which rocks were younger or older? The scientific advance that humanity achieved during the second world war allowed this question to be answered, as it was during this period that "sonar" was created, a device that is able to reveal the ocean floor
From the creation of this device, and other equipment, scientists were able to study the underwater mountains known as oceanic dorsals. During these studies, scientists were able to create methods of donating rocks and were able to conclude that the closer to the oceanic mountains the rocks were, the younger they were. On the other hand, the closer to the continent, the rocks were, the older they were. They will conclude that this must have been influenced by the phenomenon called continental drift, which refers to the movement of the masses of the planet over a period of time.

Answer:
The Antarctica is adversely affected.
Explanation:
Without Antarctic Treaty of 1961, the environment of Antarctica is adversely affected due to using it as a site for testing of weapons by the military forces of different countries. The organisms that lives in that region will be negatively affected causes decline in the population and imbalance of ecosystem as well as extinction of many organism so this treaty provides protection to the Antarctica.
