Question

3. What are the key differences between a scientific hypothesis and a scientific theory according to the lecture? Choose from the following:
a. [A hypothesis turns into a theory after very close scrutiny and acceptance by the scientific community.]
b. [A theory is an accumulation of many well-proven and well-accepted hypotheses that explain why phenomenon occurs.]
c. [A hypothesis and a theory mean essentially the same thing in the sciences. One is just slightly more proven than the other.]

4. What are the key differences between a scientific theory and a scientific law/principle according to the lecture? Choose from the following:
a. [A law explains the process of a phenomenon, but not why it occurs like a theory does.]
b. [Laws are always correct and to the point. Theories are generally ideas that can be proven wrong.]
c. [Laws can explain why a phenomenon occurs, unlike a theory.]

5. According to the lecture, what energy source is Earth using primarily for its internal processes?
a. [Interior heat]
b. [Geothermal energy]
c. [Solar energy]
d. [Radioactive Decay]
e. [Magma]

6. According to the lecture, what energy source is Earth using primarily for its external/surficial processes?
a. [Interior heat]
b. [Geothermal energy]
c. [Solar energy]
d. [Radioactive Decay]
e. [Magma]

Explanation / Answer

Ans.3) “b”

(Basically, a theory is complete set of lots of well-proven and well-accepted hypotheses that explain why a particular phenomenon occurs. Hypothesis is entirely depends on assumption.)

4.) “a”

(A law only gives detail about the process of a specific phenomenon, but it could not explain why that particular phenomenon is taking place. While, the theory provides the detailed information)

5.) ‘d’

(The primary source of energy to carry out internal processes of earth is radioactive decay)

6.) ‘c’

(The primary source of energy to carry out external processes of earth is solar energy)
