What happens when two tectonic plates collide?

Tectonic plate collisions generate tremendous force, and the results of the impact form major geological features. Some of the features are obvious to the eye, while others may remain hidden.\nOceanic plates are typically heavier, and more dense, than continental plates, so when they collide the oceanic plate is forced down under the edge of the continental plate creating a subduction zone. Subduction zones create two significant geologic formations, magma chambers and fault lines.\nOnce a subduction zone is created, the pressure pushing the two plates together still exists. When it builds up ..

What is the chemical formula for petrol?

The actual formula of petrol will differ slightly as petroleum is refined. For example, the above formula will change when pentane is changed into octane, and is further changed into diesel fuel, kerosene and jet fuel. The alkanes are also known as paraffins, and contain only hydrogen and oxygen as saturated hydrocarbons. As petrol is refined, the formula will change. For example, the formula for cycloalkanes is CnH2n, and the formula for aromatic hydrocarbons is CnHn.

How are protists helpful to humans?

Microbe World points out that just one of the ways protists benefit humans is through their production of oxygen. In fact, nearly one-third of all oxygen comes from protists, not plants. Algae are one of the top producers of oxygen in the protist kingdom.\nThe University of Alabama states that brown algae, which are part of the protist kingdom and include kelp and seaweed, are an important component of human food. Brown algae are consumed as nourishment in many cultures and contain iodine, which is essential to the proper functioning of the thyroid gland. Protists are also used to thicken cert..

What is the scientific name of "tarsier"?

Tarsiers are often described as the world’s smallest monkey because they share physical similarities with this animal. Tarsiers are nocturnal arboreal animals that are known for their distinctive big round eyes, and with their long hind legs, they can leap up to 5 meters between tree branches. Tarsiers have been around for 45 million years, making them one of the oldest land species in the Philippines, and they are found on both sides of the Wallace line.

What is the difference between mass and weight?

Mass is commonly measured in grams and kilograms, whereas weight is generally measured in Newtons. Weight changes depending on location, while mass is always constant. For example, weight on the moon is less than weight on Earth. Weight is contingent on gravity; therefore, objects are heavier when gravity is greater. Gravity does no affect an astronaut's body in space, so the astronaut is essentially weightless. While the amount of mass can never reach zero, weight can equal zero.

What is noncyclic photophosphorylation?

Non-cyclic photophosphorylation begins when a water molecule is broken down by a process called photolysis. Next, a photon is absorbed and the light causes a chain reaction that transfers energy to the core. This in turn excites the two electrons transferred to pheophytin. Taking electrons from another molecule of water makes up this deficit. These electrons transfer from pheophytin to plastoquinone and once further broken down, are released. Two H+ ions are then released and the electrons then through Cyt b6 and Cyt f, and then through plastocyanin. This creates a gradient, which provides the..

How is phenolphthalein employed in titration?

When performing a titration, a specific volume of a solution with unknown concentration is volumetrically pipetted into a flask. A few drops of phenolphthalein are added to determine if the solution is acidic or basic. If the solution turns pink, it is basic. If it remains clear, it is acidic. A stir bar and plate are employed throughout the titration to maintain a homogenous solution. For titration of an acidic solution, a basic solution with known concentration is added to a volumetric burette. The starting volume is noted. Slowly, the burette is opened and the solution is observed. When pal..

What is a pseudo order reaction?

A first order reaction is a mathematical concept that expresses decay at an exponential rate. The concept is applied to various rates of decay and is expressed in a differential equation. This equation is used to calculate the rates of decay for radioactivity and chemical reactions. Different variables can be plugged into the equation to determine various rates of decay. In the order reaction differential equation, the amount of decaying material is proportionate to the amount of remaining material. The equation is expressed as: dA/dt = -kt. The da/dt represents the rate of unit time that this..

What is the chemical formula for magnesium oxide?

Magnesium oxide is a white, odorless and crystalline solid. It has a melting point of 5,117 degrees Fahrenheit and a boiling point of 6,512 F. Its density is 3.6 grams per cubic centimeter. Although this compound’s solubility in water is poor, it is soluble in acids. However, it is insoluble in ethanol.\nMagnesium oxide is also called magnesia or magnesium(II) oxide. It has medicinal applications and may be prescribed as an antacid for heartburn. It also functions as a laxative and a dietary supplement.
