Why would the use of a ruler not be effective to measure the thickness of your foil?

It might be challenging to estimate the thickness of a thin layer of a substance. If a micrometer is available and the material is not too thin, it can be used to measure thickness directly. In the absence of a micrometer, thickness measurement must be done indirectly.

<h3>How is the thickness of aluminum foil determined?</h3>

All that is required of us is to cut a piece of the problematic aluminum foil, measure its height and length (so that we can determine its area), crumple the foil into a small ball, and weigh it using a milligram balance. The information needed to indirectly calculate the aluminum foil's thickness will then be available to us.

<h3>What measurement unit is best for representing the thickness of the foil?</h3>

The foil will likely be roughly a micrometer thick, which translates to a thickness of 1 x $10^{-4}$ cm in centimeters. Since an atom is roughly $10^{10}$ m in size, there will be 1 x $10^{4$ atoms in a unit of 1 x $10^{-4}$ cm.

The correct answer is D) There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen.

Life on Earth could be affected if the atmosphere did NOT contain greenhouse gases in the following way: "There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen."

Scientists agree that this is basically the importance of greenhouse gases on the atmosphere of planet earth. Without these gases, the surface of the earth would have an average temperature of minus 18 centigrades. Many life forms as we know them could not survive under this hairs climate condition. Furthermore, most of the surface of the earth would be covered on ice.
