because it's hard for scientists to be able to get clear pictures down at that level, 1000's of feet below the surface because the pressure is so high, it's so far down, and it's so dark. when sonar came out scientists were able to know what was down there without actuallly taking pictures. It's like with a bat. The bat doesn't actually have to see what's in front of it to know what's down there because, by using it's sonar, it's able to sense the vibrations off of the objects.

Toricelli was not known for contributions about composition of matter.
Scientists usually publish their new ideas in a scientific journal. They can also hold a symposium to discuss the ideas, if they wish.
Scientists test ideas about chemical evolution by using computer models.

Sir Newton indeed took other scientist's ideas but he improved on the ideas. Which is pretty much how all scientists work.
They change their minds because they saw that the structure changed and it grew into a different size and it grew alot more details on them. Thats how scientists sometimes change their ideas about classifying organisms
The first one is the sonar used to map out sensed mountains,the second one is scientists found strange rocks shaped like pillows in the central valley of the mid-ocean ridge and the last one is scientists discovered that the rock that makes up the ocean floor lies in pattern of magnetizied "stripes"
