Which study involves both Earth science and physics?
Calculating how much energy is associated with a hurricane
,Measuring the energy produced by a generator
Comparing the composition of crude oil from different regions
Monitoring changes in phosphorus levels of a lake - (answer)Calculating how much energy is
associated with a hurricane
Which question could be answered with a controlled experiment?
Does ice melt faster in an empty glass or in a glass full of water?
Do all planets have the same shape of orbit around the sun?
What is the maximum distance between Earth and Jupiter?
What is the length of the longest river in North America? - (answer)Does ice melt faster in an
empty glass or in a glass full of water?
Which topic would be appropriate for a controlled experiment?
Determining how fast different chemical pollutants dissolve in water
Comparing the elements present in different stars
Measuring how fast a river flows
Predicting the path of a tornado - (answer)Determining how fast different chemical pollutants
dissolve in water
Which question requires a controlled experiment to answer?
Which type of rock contains the most calcium?
Which planet has the most moons?
Which elements are found in Earth's atmosphere?
Which fossils formed earliest in Earth's history? - (answer)Which type of rock contains the most
calcium?
,Sir Isaac Newton discovered that the force of gravity between two masses increases if the masses
increase, and decreases if the distance between the masses increases. No experiments have ever
contradicted this relationship.
Which type of scientific statement is this?
Hypothesis
Theory
Law
Prediction - (answer)Law
The well-accepted scientific explanation for many characteristics of Earth's crust states that the
crust is broken into several large plates. These plates move slowly over the mantle below
because of convection and other processes. Earthquakes and volcanoes are most common at
places where the plates interact. Evidence from physics, chemistry, and geology supports this
explanation.
Which type of scientific idea is this explanation an example of?
Hypothesis
Theory
Law
Prediction - (answer)Theory
A student proposes that sugar will dissolve faster in rubbing alcohol than in water. The student
reasons that sugar and rubbing alcohol both contain carbon so they will mix more easily.
Which type of scientific idea is the student's proposal an example of?
, Hypothesis
Theory
Law
Observation - (answer)Hypothesis
Why was the shrinking Earth idea replaced by the theory of plate tectonics?
Plate tectonics was a new theory, which made it more reliable.
Plate tectonics explained observations about Earth that the shrinking Earth idea could not
explain.
Geologists voted on which theory to accept, and chose plate tectonics.
Many well-known geologists were involved in proposing plate tectonics. - (answer)Plate
tectonics explained observations about Earth that the shrinking Earth idea could not explain.
Astronomers have long accepted that plate tectonics exists nowhere in our solar system except on
Earth. In 2011, a scientist analyzed 100 NASA-space-mission photographs of Valles Marineris
on Mars, the longest known series of canyons in the solar system. The scientist found that Valles
Marineris showed features found only in locations on Earth where major tectonic plates divide.
What would be the appropriate response of scientists to this information?
Reject plate tectonics on Mars as the explanation because it contradicts accepted science
Decide whether to accept plate tectonics on Mars based on the reputation of scientists involved
Hold public debates among scientists and then vote whether plate tectonics occurs on Mars
Carry out further research to gain more understanding of possible plate tectonics on Mars -
(answer)Carry out further research to gain more understanding of possible plate tectonics on
Mars
