The United states has one of the largest demand for energy in all forms. One common way to get the energy we need is through hydraulic fracking, but it has become more controversial as we know more about it. This paper will discuss what Hydraulic fracking is, what has been the recent controversy around it, and finally what effects the injection of wastewater has on the ground water and seismic geology of the region. Generally speaking, hydraulic fracking is the process of drilling a hole and…

Hydroxyapatite (HA) has been studied for their excellent performances which are suitable for use in bone defects or regeneration of bone. Hydroxyapatite (HA) has poor mechanical properties which make it limited used in a load bearing area. In this case, sodium alginate (SA) was used to be mixed with hydroxyapatite (HA) by using precipitation method to increase the mechanical and physical properties. The mixing of hydroxyapatite/sodium alginate effectively increases the densification and hardness…

Climate change's equally evil twin is the name for ocean acidification its harmful because of the excess amount of carbon dioxide in the atmosphere. Since we don't see or feel it because the effects are happening underwater. CO2 is released by burning coal,oil and gas but its doesnt stay in the air but it dissolves into the oceans. The oceans have absorbed 525 billion of CO2 from the atmosphere and they collect about 22 tons per day. Scientist thought it was it good thing because it wasn't…

Our current problem, global warming caused by the growing amount of emissions, can no longer be swept under the rug. As we all know, global warming is caused by carbon dioxide going into the atmosphere. But, now there is a possible solution of burying it deep underground or beneath the ocean. The burning of fossil fuels poses a great threat to rising sea levels, stronger storms, and agricultural disruptions. Most importantly the global temperature level rising. Humans are in risk with carbon…

Introduction The contamination of large bodies of water is becoming a greater problem across the world due to our rapidly increasing population. People commonly pollute these areas with their release of waste products and trash, and these contaminants can spread from small streams or lakes to oceans and complete ecosystems. The pollutants that are released into the water sources are often inorganic substances, and the dissolved forms of these compounds can become ionic cations and anions. An…

Solubility Phosphates are not very water-soluble, thereby creating a limiting potential for plant-growth in marine ecosystems. This explains its encompassing effect on the surface of affected water system, as observed in the Watershed Nature Centre. In addition, this can be observed from the site as less quantity of phosphorus get dissolved in running water compared to the amount that eventually gets into the water column. Temperature: The water surface gets heated up by sunlight, increasing…

• • Introduction Mars, a rocky, frozen, geologically dead and dry planet in our Solar system, but has polar ice caps and atmosphere, seasonal patterns, canyons, volcanoes and valleys.(nasa journey to mars) Mars is the fourth planet from the Sun and in possible habitable position similar to Earth. Mars is the most intriguing and most observed object in space after the Moon for centuries, and a reason is very simple; Mars is visible from Earth in nighttime. Observation from the Earth…

side) and oral shield (oral side.) Unlike sea stars in class Asteroidea, spiny brittle stars have unbranched arms that are setting off from the central disk. Each arm is covered with large, well-developed ossicles called spines—spines are made up of calcium…

Over the past decade the accounts of various coral diseases have been on the rise which had lead to the decimation of keystone species of corals throughout mainly the world’s tropical oceans. Since the mid-1990s, 18 coral diseases affecting at least 150 scleractinian, gorgonian, and hydrozoan zooxanthellate species have been described in the Caribbean and Indo-Pacific (Sutherland et al. 2004). Most of these diseases have been caused by bacterial, fungal, and protist type pathogens as well the…

Coral reefs are one of the most diverse and valuable ecosystems on earth. According to the National Oceanic and Atmospheric Administration, coral reefs support more species per unit area than any other marine environment, making them the equivalent of an aquatic rain forest (Kitch and Edwards). Occupying a mere one percent of the seafaring environment, coral reefs are home to more than one quarter of all known marine species. This translates to approximately four thousand species of fish,…
