Which of the following are part of Lyell's principle? (Choose as many as apply): Group of answer choices   Water has a specific freezing point, and its characteristics, once frozen, are different than its characteristics when liquid.   Sometimes, gravity is briefly suspended on Earth.   Gravity works in the same way everywhere on Earth.   Sedimentation rates of sand in water are  the same, if the sand is the same  and the water is of the same volume and momentum.   Water always seeks its lowest point.

Scientific Notation

We have to deal with quantities that are extremely large or very small. For example- I may have 6,500,000,000 red blood cells, or the diameter of an iron atom is 0.000000011 inches. Numbers with many zeros can be inexpedient to work with, so scientists use scientific notation. It represents very large numbers or very small numbers in a simple form. We know that whole numbers can be extended to infinity, but we cannot write such large numbers on paper. Numbers that present in millions of places after the decimal point need to be represented simply. Thus, it is difficult to represent a few numbers in their extended form. Therefore, we use scientific notation.
