Question 22 (Essay Worth 3 points) (02.01 HC) A prediction of the theory of Plate Tectonics is that new volcanoes can form at th
Darina [25.2K]

Answer:

What would be the expected result of the experiment?

For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.

But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.

How would you interpret the results if the scientist observes no new volcanic activity?

I would say that does NOT invalidate the theory because the observation period is extremely short.  10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all.   Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.

The sum total of the interactions of the variety of organisms in the biosphere is called:_________
ASHA 777 [7]

The sum total of the interactions of the variety of organisms in the biosphere is called biodiversity.

The term "biodiversity" describes the wide range of organisms that are alive today, including flora, fauna, bacteria, and fungi.

The vast variety of life on Earth is referred to as biodiversity. It can be applied more precisely to all the species found in a given area or ecosystem. Every living creature, which include plants, microbes, animals, and people, is referred to as biodiversity. Around 8.7 million species of plants and animals are thought to exist, according to scientists. However, to date, only about 1.2 million species, the majority of which are insects, have been recognised and described. This means that the identities of millions of other organisms are still unknown.
