You can reduce wind erosion by providing a protective plant cover for the soil.
Explanation:
Surface tension is the energy required to increase the surface area of a liquid by a given amount. The stronger the intermolecular interactions, the greater the surface tension. ... The viscosity of a liquid is its resistance to flow. Liquids that have strong intermolecular forces tend to have high viscosities.
The surface tension in plain water is just too strong for bubbles to last for any length of time. ... This separates the water molecules from each other. Since the surface tension forces become smaller as the distance between water molecules increases, the intervening soap molecules decrease the surface tension.
There are many pieces of evidence provided as strong evidence: fro example the Comparative anatomy of many species. <span>This evidence is based on compares of the the skeletons of humans, cats, whales, and bats, illustrating how similar they are even though these animals live unique lifestyles in very different environments. Another piece of evidence is </span><span>biochemistry of all living things on Earth. This is so because is incredibly similar. This shows that all of Earth’s organisms share a common ancestry.</span>
Tempurature of a substance.
<em><u>I believe that the answer are 3, 4, and possibly 5 </u></em>because the 1st question says, ''Where on earth''. It should have been, ''When on Earth''. The others make sense because the scientist or your teacher can test it. Their has to be evidence to support it.
#1 can't be tested because it was in the last decade (which was 10 years ago). Also, it says in #1 that, Where on Earth had a population decrease.
Hope this helps... :)
