Answer:
Why don't you just look it up on google they have really good poems and you can change the words around so it's not plagiarism
Explanation:
Answer: D) Tree roots improve soil water retention
There are many reasons which states that deforestation increases the risk of flood. First , some water stay on the leaves and evaporates in to the atmosphere. Second, tree leaves reduce the impact of raindrops on the soil which causes less soil erosion.
Third, tree roots absorb water from the soil, which make the soil dry and it absorb more water rainwater. The roots of tree hold the soil in place and reduce the movement of sediment which reduce the capacity of river to break its banking. Thus, reducing the chances of flood.
It allows the scientist to determine the age of the rock it is in
The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.
Explanation:
- A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
- Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
- The pH is then equal to minus the logarithm of the concentration value.
- Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
- The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
- Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.
