Concept #3 Quiz
Choose the best possible answer to the following questions about Key Concept 3 "The scientific method and geology."

This activity contains 5 questions.

The scientific method is the standard used by scientists so that _______.

we ask a question based upon our observationswhen hypotheses “pass” tests, we should devise additional tests until the hypothesis failsobservations are used to make hypotheses that are required to be “testable”all of these

Using the scientific method, it has been deduced that the Earth is ________ years old .

~ 3.8 billion~ 13 billion~ 2.0 million~ 4.5 billion~ 200 million

All of the following are true about the scientific method except ______.

a hypothesis that passes a test is considered a facthypotheses necessarily allow predictions to be madehypotheses explain observations, but must be tested for validitya hypothesis is different from a theoryhypotheses are constructed to explain observations

Which of the following explains best the difference between a hypothesis and a theory?

A hypothesis is a series of observations, and a theory is a model that explains them.A hypothesis is the same as a theory, just named by different scientists.A hypothesis is a model that has passed a series of tests, but a theory explains a set of observations.A hypothesis is developed to explain observations, but a theory is a hypothesis that has passed a series of tests.A hypothesis is a model that requires testing, but a theory is a fact.

In the late nineteenth and early twentieth century, scientists used the scientific method to explain the movement of glaciers in Switzerland. Which of the below statements best explains the observation that follows:

The glacier is shown to be flowing in the downhill direction. At the same time, the glacier’s snout (terminus) is shown to be retreating in the uphill direction and the glacier’s ice volume is decreasing.

Rocky debris in the valley downhill from the snout was deposited by Noah’s flood.The melting rate of ice in the glacier exceeded the rate at which new snow and ice were added to the glacier.The glacial hypothesis was finally accepted as scientific theory.Cooler temperatures meant slower forward glacier flow resulting in snout retreat uphill.
