Surface water

The heaviest. Feels gritty and falls apart Crumbles No smear Few nutrients Dries quickly Does not hold water well Silt Just enough big to see them with a magnifying glass. Not as heavy as sand but heavier than clay Holds together, feels smooth and powdery Holds together, moderate crumbling, cannot be rolled in a strand Some smear More nutrients than sand Takes a longer time to dry. Holds water better than sand. Clay You need a microscope to see them. Ligther than sand and silt. Feels slippery…

certain situation that is affecting the water quality of a particular body of water in our neighborhood. The body of water that we will be focusing on today, will be the Foxstone Creek in Vienna Virginia. Although there are many different problems that have occurred in this creek, the problem that we noticed that is the most impactful, is the amount of erosion on the creek. Erosion is the process by which the surface of earth is being worn away because of water, ice, wind, waves, and other…

property of water. It is the ability of water to move upward against gravity. Water moves in between spaces due to forces of adhesion, cohesion and surface tension.Adhesion of the surface the water is sticking to makes the water able to be moved up, surface tension acts to hold the water to the object the water is moving on, and the capillary action is when the water is moving upward on the surface of another object. Here are some examples. When a little kid spills water on the table…

Water is one of the most important and essential fluid to our human body. We use and drink water almost 24 hours a day and 365 days a year, however, many of us probably have never thought of and find out what are the chemical and scientific reasons behind the importance of water. Approximately 50-65% of the average adult human body is water, however, this varies based on a number of factors such as age, health, weight and sex. In males, it is normally about 60% of the body weight. In…

Turbidity: - Turbidity is a degree of water clarity. Turbidity is defined as an “expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample”. Nephelometers are used to measure the intensity of light scattered by contaminants present in water such as suspended and colloidal solids like clay, silt and microscopic organisms. Turbidimeters using the principle of nephelometer compare the light scattered due to…

A water molecule is made of two hydrogen atoms and one oxygen atom. Oxygen and Hydrogen are gases but when combined form into a liquid compound; water. The hydrogen atoms make an angle of around 105 degrees with the oxygen atom. The oxygen atom dominates an end of the molecule while the hydrogen atoms dominate the other. The asymmetry of the water molecule causes the oxygen end to have a slight negative charge while the hydrogen end has a slightly positive charge. A molecule with both (-) and…

How To Prevent Algae And Moss Damage From Happening To A Cedar Roof One thing that can cause damage to a cedar roof is algae and moss growth. It will eventually cause rooting and cracking, as well as the potential failure of your cedar roofing. In order to get the longest lifespan possible from your cedar roof, you’ll need to follow some tips to prevent the algae and moss growth from occurring. Get An Annual Roof Inspection If you do not work with roof every single day, you may not be aware of…

two hydrogen atoms and one oxygen atom come together they form water. Water is one of the most important things that humans need to survive. It is so important that humans can’t go more than four days without it. Water effects in more ways than you could imagine. It shapes the land we live on and has been doing so for tens of thousands of years. What makes this all possible is the water cycle. The cycle starts with evaporation. Water evaporates from lakes, rivers, streams and the ocean. It…

pervasive contaminant of drinking water substances in some of metropolitan regions. Perchlorate is stable beneath normal atmospheric conditions and particularly soluble in water. When a perchlorate compound is released into the environment, it will dissolve in water, and because of its capability to adsorb directly to surfaces, it will be transported thru bulk movement of water and mixing processes (Srinivasan & Viraraghavan, 2009). When the flow is much less or if water turns into stagnant,…

Bible water is mentioned. Genesis 1:2 describes “the earth… formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.” Before anything else, water was the only thing existing on earth, validating its importance to the earth and mankind. Water is so important that it is referenced over 722 times in the Bible. All living creature’s depend on water to survive, since their mass is made up of 70-90% water. The continuous movement of water…
