Surface water

Thanks to its carved topography, researchers have always suspected that Mars was once home to several rivers, lakes, and perhaps even oceans. There has even been some speculation about the existence of frozen water deep beneath the ground. However, finding evidence of liquid water in the present day, has been a little elusive. That is why NASA's September 28th announcement that confirmed the detection of liquid brine on the Red Planet caused so much excitement. The first indication of the…

Water is essential for life to exist on Earth. It exists as a solid, liquid, and gas and is common in every state. Covering about 75% of Earth’s surface and 70-90% of mass in living organisms, water is the most abundant liquid on Earth (Sarquis). In the Bible, water is mentioned many times in the Old and New Testament. The unique physical properties such as hydrogen bonding, evaporation, and surface tension are mentioned in the Bible and help to prove the existence of a Creator through not only…

1: The Effect of Species Type on Mass Specific Gill Arch Surface Area The sample size of our experiment was 4 groups (N=4). The height of the bars represent the average mass specific surface area for the four classes from whom the data was collected from, in cm2/kg. The first bar represents the average mass specific surface area for the species Scomber scombrus, or the Mackerel Fish. The second bar represents the average mass specific surface area for Merluccius bilinearis, or the Silver Hake,…

gallons of untreated sewage, storm water, and industrial waste are dumped into U.S. waters. Stormwater, according to United States Environmental Protection Agency, is runoff that flowed through any surface modified by humans. With the addition of more urbanized areas, the increasing damages of stormwater which has been revealed as a danger to life. Storm water damages all life, including mankind. More specifically, stormwater damages the aquatic life due to the water chemistry changing. Metals…

for living organisms, water is used in different ways such as solvents, temperature buffers, metabolite and the living environment. In the solvents, the oxygen atoms of water molecules attracts the cations and by extension the water molecules around it. The more water molecules being attracted the more Hydrogen ions are being formed between them. As a result of this, there is a cluster of water molecules around the ions, therefore the ions are hydrated. Anions also attract water molecules; in…

about the importance of water and why it is one of the most important substances in the universe, I enjoyed this video on YouTube called Water – Liquid Awesome: Crash Course Biology #2. We can start by expressing that it is important to know that water is the only substance on our plant that occurs naturally in solid, liquid and gas forms. All life on earth is dependent on there being water. Water (H2O) is a covalent bond which is made up for two hydrogens and one oxygen. Water has a different,…

rainwater in California. This drought means that the farmers can’t rely on surface water, so the farmers that haven’t lost their jobs are resorting to their last option, drilling deeper underground for more water sources. Two decades ago wells were usually about a couple hundred feet, but in the modern day wells have come to be considerably deeper. Farmers are now drilling up to two thousand feet underground for more water. The state of California doesn’t restrict the amount of groundwater usage…

in part the effect of this current. (J. H. Tuckey, 1815) Ocean currents are water movement and circulation forms that effect climate zones and weather patterns around the world. The directions these currents take can be affected by climate, actions of celestial bodies…

operations. While most of the military like to stay on land or the surface of the ocean, submarines like to stay hidden deep under the surface of the ocean. The priority is to make the ship sturdy and watertight. Submarines are ships that can stay underwater and also float on the surface. As you walk on the top of the submarine, you start seeing how this massive machine is built to remain silent as it moves through the water. As you get closer to entering the submarine, you begin to wonder…

towards the environment, which may help with improvements and the growth of the land by applying smaller amounts of water over a longer amount of time. This helps extend the watering time for plants in order to prevent soil erosion. If the irrigation needs have to be changed a drip irrigation system is very easy to modify and adjust to grazers and farmers. This type of system only delivers water when its needed to be given. When plant and land conditions get moist, this can help against the…
