Question

In 1915, Alfred Wegener proposed the continental drift theory. He said that the continents floated on top of the mantle. Wegener predicted that heat rising within the hot mantle created currents of partially melted rocks that could move the continents around the Earth’s surface. Like many revolutionary theories, Wegener’s was not initially accepted by scientists. 1915 to the 1960s. These effort of scientists over a span of fifty years shows us some important characteristics of the nature of scientific and scientific research that include ALL BUT one statement list here.

D Scientific knowledge is the result of the collection of evidence gained from research by the scientific community.Scientific knowledge is the result of the collection of evidence gained from research by the scientific community.
Question 2
Scientists continue to compile evidence supporting the theory of continental drift, further expanding those ideas to explain plate tectonics. Consider the technological development over the last 50 years. What is the most recent piece of evidence supporting the continental drift theory?
Responses
A magnetic reversals of seafloor materialsmagnetic reversals of seafloor materials
B direct measurement using satellite technologydirect measurement using satellite technology
C fossil evidence supporting the law of superpositionfossil evidence supporting the law of superposition
D radioisotope dating of minerals found in Earth's strataradioisotope dating of minerals found in Earth's strata

Answer 1

Q1: B — Scientists do not rely on the efforts of others to support or reject proposed theories. (This is false.)

Q2: B — direct measurement using satellite technology (e.g., GPS measurements of plate motion).
