Varies
Explanation:
From the differences in the width of the alternating stripes, we can conclude that the lengths of time represented by this evidence varies.
Normal and reversed polarity do not have equal length of time when they occur.
- The paleomagnetic field just like the earths geomagnetic field we have today varies from time to time.
- During period of normal polarity, the north pole of the geomagnetic field is close to that of the earth.
- At reversed polarity, the north of the magnet changes position.
- Their is no regular interval to this
- Magma that are getting magnetized during this period will have different variations in the width of the magnetic fields.
- The width of the stripe shows the duration of the anomaly.
- Since the geomagnetic field takes their root from the core, the intensity varies and it affects the extent of magnetization of magnetic minerals in rocks.

Answer:
Explanation:
The theory of uniformatrianism was proposed by James Hutton, a Scottish Geologist by profession.
This theory was a contrast proponent to the tenets of the theory of catastrophism in existence before then in the scientific circles
The theory states that "the present is the key to the past and geologic processes occurring today have happened in the times past".
- The theory correlates geologic processes as continuous in nature rather can punctuated situations.
- Erosion occurring today has been changing the land surface on earth as far back into the geologic times and periods.
- From the image, the erosional activities are still continuing today.
Answer:
Effect of independent variable is studied on the dependent variable or subject of the experiment.
Explanation:
The independent variables are very important in an experiment. Basically the affect of an independent variable is studied on the subject or dependent variable.
Thus, it can be said that independent variable will produce the effect on the dependent variable.
Here in this case the different types of disinfectants are the independent variable and their effect will be observed on the bacteria (subject or dependent variable)
