Which statement about a hurricane is an inference?

• The windspeed is measured at 200km/hr

• The central air pressure is recorded at 946.0 mb

• A rain gauge records three inches of rain in less than one hour.

• Damage from the storm is expected to be extensive.

Answer explanation

This is a prediction for the damage done, it isn't something that was measured.

Which procedure is an example of classifying observed data?

• grouping stars by brightness

• graphing temperature versus time for a particular date

Base your answer(s) to the following question(s) on

the Earth Science Reference Tables, the diagrams

below, and your knowledge of Earth science. The

diagram represents particles of the same type

of sedimentary rock material collected from a

streambed. The diagrams are drawn actual size. Which inference about the density of particle A

and particle B is most accurate?

• Particle A and particle B have the same

  density because they are made of the same

  material

• Particle A has a greater density than particle B

  because particle A has a greater volume

• Particle A has a greater density than particle B

  because particle A has a greater mass

• Particle B has a greater density than particle A

  because particle B has been worn to a smaller

  size

Oil and water are added to a beaker. The beaker in the figure below shows the oil and water after they have separated. Which of the following is an inference that explains the result of the experiment represented by the figure?
