Phototropism is a reaction to environmental factors. It is a plant's response to sunlight in the form of movement. In plants, phototropism is very prevalent. In actuality, it is necessary for plant growth. Other plant movements also occur in response to touch, water, gravity, and other factors. Phototropism was discovered due to well-known experiments by Charles Darwin and Boysen Jensen.
There are two types of phototropism:

Student 1’s methods would be more accurate, because the student would control more factors. Only one variable at a time (either temperature or acidity) would be tested on each group of worms. On the other hand, Student 2 is testing both factors on all the worms, which could make the results unclear.
It really is impossible to predict such a matter. I mean, think about it, its nearly impossible to think about how earth would be impacted if the heat from the interior of the planet that powers plate tectonics were to suddenly cease to exsist, or if that heat never exsisted in the first place, because that is how planets are formed.
One thing is certain however, life wouldn't be the same without plate tectonics; in one case, the constont transgression/regression, sue in large part of tectonic forces acts as a evolutionary pump forcing life to evolve. EXAMPLE: the evolution of plants from marine to terrestrial settings. Without plate tectonics, life would certainly be dramatically different.
