![Page 2: Scientific Method. Which of the following statements is a testable hypothesis? A) The number of earthquakes in California will increase by 10 percent.](https://reader036.fdocuments.us/reader036/viewer/2022082612/56649e9c5503460f94b9d3af/html5/thumbnails/2.jpg)
Which of the following statements is a testable hypothesis?
A) The number of earthquakes in California will increase by 10 percent over the next 50 years
B) Dark plastic and white plastic will heat up at the same rate
C) Soil on a steep hill will erode more quickly than soil on a gentle slope, because the steep hill gets more sunlight.
D) A sugar cube will dissolve slower than loose sugar of the same mass, because it has less surface area.
