Question

Ben is a geologist at a state park. The park experiences mild tremors several times a month. Ben has recorded the dates and times of the following tremors:
Date Time Strength of Tremor
(Moment Magnitude Scale)
7/06 18:31 0.4
7/08 2:12 1.1
7/13 11:01 0.8
7/13 22:45 1.2
7/15 5:37 1.1
7/16 13:22 1.3
7/17 1:02 0.9
7/18 12:59 1.4
7/18 20:18 1.1
Which of the following is an observation that Ben has made?
A.
The park has several active faults.
B.
On July 8, the tremor in the park measured 1.1 on the moment magnitude scale.
C.
The frequency of the tremors in the park will likely increase over time.
D.
If the tremors become stronger, they will begin to damage structures in the park.

Answer 1

Answer:

A

Explanation:

"On July 8, the tremor in the park measured 1.1 on the moment magnitude scale" is an observation because it is a measurement that can simply be read off the data table.
