Question

2 multiple choice 2 points joannes science teacher cautioned the class to be skeptical when learning about new scientific discoveries. why is it important to be skeptical about new discoveries in science? because many scientific discoveries are not based on facts because most scientific discoveries have no scientific value because most scientists make errors when formulating scientific discoveries because all scientific discoveries must be examined critically before they can be accepted 3 multiple choice 2 points when alfred wegener first proposed his theory of continental drift, most earth scientists did not immediately accept it. many expressed skepticism because the theory did not explain what force was strong enough to move continents. later, scientists investigating continental drift found evidence that explained how continents are able to move. plate tectonics, which grew from the theory of continental drift, now explains how continents move over time. how was the initial skepticism of earth scientists useful to the scientific process? skeptical comments showed that continental drift was not a correct explanation of wegeners observations. the skeptics kept people from forgetting about earlier observations that did not support continental drift. the scientists who were skeptical kept earth science from changing views too rapidly. the skeptics raised questions that became the starting point for new investigations.

Explanation:

For question 2: In science, skepticism is crucial as all scientific discoveries must undergo critical examination before acceptance. This ensures validity.
For question 3: Skeptics' questions (like about the force moving continents) became the impetus for new investigations (leading to plate tectonics).

Answer:

1. because all scientific discoveries must be examined critically before they can be accepted
2. The skeptics raised questions that became the starting point for new investigations.
