One method I know of is comparing a sample of the rock to other samples which the scientist already knows the age of. I forgot what this method is called but I know it's used by lazy scientists that use other scientist findings like the age of a rock to compare to their own work
The sun is the source for photosynthesis
Answer:
the molecules are farther apart in ice than in liquid water.
Explanation:
The correct answer would be that<u> the molecules of water are farther apart in ice than in liquid water.</u>
<em>Water molecules in ice form are usually less dense than water molecules in liquid form. The water molecules in ice usually arrange themselves in a lattice form, unlike the random form in liquid water. This arrangement makes water molecules in ice to be more evenly spread out than in their liquid counterpart. Thus, ice is usually less dense than liquid water and will obey the principle of flotation by floating on water. </em>
