The Nazca plate, named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South American. The ongoing subduction, along the Peru- Chile trench, of the Nazca Plate under the South American Playe is largely responsible for the Andean Orogeny
Good luck! Hope this helps hun ;)
The answer is true. Tourism produced an estimated 14 percent of the region’s Gross Domestic Product in 2013, but, the ships that bring in the tourists dump waste into the ocean
Answer: D. It can melt to a depth of a few meters in summer, then refreeze in winter.
Explanation:
Permafrost is ground which remains frozen for two or more years. Permafrost consists of soil, rock and sand fused together by ice. Mostly found in areas in high altitude, the Arctic, Antarctica, it is common in periglacial environments where temperatures are below freezing
.
The topmost layer of permafrost can melt in summer and refreeze in winter. This thawing and refreezing produces a ground pattern called columnar joints similar to the one formed when molten lava cools.
The fossil range can simply be defined as the time period in which an organism has existed, thus left fossil traces of its existence. The fossil range can be very short, medium, or long, thus usually there are limitations before certain type of organism evolves into another species, thus eliminating the ancestral organism from the fossil records. On the other hand, there are organisms that have incredibly big fossil ranges of several hundred million years, and since they emerged, they have remained almost unchanged. Those kind of fossil ranges are very rare though, and they don't represent the general picture. Most of the fossil ranges are between several thousand years and several million years, as that is usually how much a species exists, ending its reign, be it because of competition, changes in the environment, or big natural disaster.
Answer:
<h3> The continents are the divisions of the earth space elaborated by man to better understand it. These are large landmasses that are separated by the oceans. Thus, according to the current division, there are six major continents: America, Europe, Africa, Asia, Oceania and Antarctica.
</h3>
<h3> Oceans are portions of water that occupy the major and largest depressions of the planet's relief. It is, therefore, an immense set of water mixed with other elements, mainly mineral salts, and that surrounds the areas formed by the emerged lands, which includes islands and continents. If we consider that oceans, unlike seas, are not surrounded by continents on at least three sides, we can say that there are only three oceans: the Pacific, the Atlantic, and the Indian, since the Arctic and Antarctic Glacial Oceans would be, indeed large seas (or a set of seas)</h3>
Explanation:
<h3>The earth can be organized into 4 oceans, 7 oceans and 7 continents hope that helps</h3>
