Which two disciplines of physical science does this scientist use?
Choose 2 answers
Astronomy

3. 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✔✔✔ Calculating how much
energy is associated with a hurricane
,4. 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?✔✔✔ Does ice melt
faster in an empty glass or in a glass full of water?
5. 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✔✔✔ Determining how fast different chemical
pollu- tants dissolve in water
6. 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?✔✔✔ Which type of rock
contains the most calcium?
7. Sir Isaac Newton discovered that the force of gravity between
twomasses 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✔✔✔ Law
8. 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
