There's a subtle point involved here that I'll try to explain, and
I hope you catch my explanation:
A real scientist does NOT "use evidence to support his theory".
That would mean that he dreamed up his theory, then he went
around observing the world and nature, and he wrote down and
took pictures of things he saw that supported his theory, and he
ignored anything that didn't support it. This is exactly how science
does NOT work. Anybody who operates that way is laughed out
of science and you never hear about him again.
The way science works is exactly the opposite: The curious
investigator observes the world and the things around him. He
sees how things actually work. That's the 'evidence'. Eventually
he comes to the point where he's ready to build a theory of WHY
or HOW things work the way they actually do.
The theory is built to explain the evidence. The evidence is not
used to support a theory. And after the theory is offered, the next
step is to test the theory and see if it's worth anything.
Wegener observed that m<span>ountain chains are continuous across
continents, and he learned that similar fossils have been found
on different continents. When he saw these and other facts, he
eventually offered the theory of continental drift, to EXPLAIN the
evidence.
I only see 5 points. Where are the other 19 ?

Try to access drinkable water
The hardness of the water is given by the presence of calcium and magnesium <span>carbonates. The mixing of these minerals in water turns the water more alkaline.
</span><span>The Langelier saturation index uses the pH to predict the calcium carbonate stability of water. So, through the pH, it is possible to know whether a water is more or less acidic.</span>
The correct answer for the question that is being presented above is this one: "TRUE." <span>During an earthquake, seismic waves move outward from the focus in all directions. The statement that is being presented is True. Seismic wave tends to move outward if there's an earthquake on going.</span>
Angola has a population of 21 million people. Sierra Leone has a population of 6 million people. Democratic Republic of the Congo has a population of 68 million people. <span>Cote d’Ivoire has a population of 20 million people. Therefore, Democratic Republic of the Congo has the highest population of the following African countries.</span><span />
