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 ?

The flow of heat from Earth's interior to the surface is estimated at 47 terawatts<span>(TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of </span>isotopes<span> in the mantle and </span>crust<span>, and the primordial heat left over from the formation of the Earth.</span>
first, it's "which" and what are the options?
Wind erosion is occurred when pieces of the earth are worn away by the strong winds. It occurs in dry bare areas when wind blows and moves the dirt around. Wind erosion causes damage to the crops by removing the soil which crops needed from it. ... Water erosion is the more powerful erosion than wind erosion.
I dont know about Glacier erosion.
hope this helped!
