Question 1

Which statement best distinguishes a scientific theory from a scientific law in Earth and space science?

A theory explains why patterns occur, while a law describes a consistent pattern or relationship. A theory becomes a law after it has been tested for many years. A law is a guess, while a theory is an untested explanation. A theory applies only in laboratories, while a law applies in nature.

Correct Answer:

A theory explains why patterns occur, while a law describes a consistent pattern or relationship.

Question 2

The eventual acceptance of plate tectonics depended most directly on which new line of twentieth-century evidence?

Discovery that continents have different climates Mapping of symmetrical magnetic stripes on both sides of mid-ocean ridges Observation that rivers erode valleys over time Recognition that the Moon affects ocean tides

Correct Answer:

Mapping of symmetrical magnetic stripes on both sides of mid-ocean ridges

Question 3

Ice-core studies of past climate most clearly show how Earth science uses which other discipline?

Organic chemistry, because pollen grains are converted into petroleum in ice Analytical chemistry, because trapped gases and isotope ratios are measured to infer past atmospheric conditions Classical mechanics, because all climate information comes from orbital speed alone Human anatomy, because ice cores preserve complete animal bodies

Correct Answer:

Analytical chemistry, because trapped gases and isotope ratios are measured to infer past atmospheric conditions

Question 4

Which question is most directly testable through a school-based Earth science investigation?

Is sandstone more beautiful than shale? Does increasing stream-table slope increase the rate of sediment transport? Should every city ban development near rivers? Was the first volcano frightening to nearby people?

Correct Answer:

Does increasing stream-table slope increase the rate of sediment transport?

Question 5

A class investigates whether soil particle size affects infiltration rate. Which variable should be measured as the dependent variable?

The type of container used for all samples The amount of water poured onto each sample The elapsed time or rate at which water passes through each soil sample The starting temperature of the classroom

Correct Answer:

The elapsed time or rate at which water passes through each soil sample
