1. What is Earth’s mantle? The mantle is a part of a terrestrial planet or other rocky body large enough to have differentiation by density. The interior of the Earth‚ similar to the other terrestrial planets‚ is chemically divided into layers. The mantle is a layer between the crust and the outer core. ... 2. What elements make up the Earth’s mantle? Magnesium‚ silicon‚ iron and oxygen‚ aluminum‚ silicon‚ calcium‚ sodium and potassium 3. Describe the “big splash” theory of the Moon’s origin? The

Encoding Information with Light’s Orbital Angular Momentum Light is the future of communication‚ traveling at 3‚000‚000 meters per second‚ the cosmic speed limit of the universe. Its tremendous speed makes it optimal for data transmission. The conventional method to encode information in light is through amplitude modulation‚ i.e. light pulses‚ time division multiplexing‚ i.e. delaying the time light beams enter a channel‚ and wavelength multiplexing‚ i.e. multiple beams of light in one channel

Plate Tectonics The forces that shape the earth begin beneath the lithosphere. Rock in the asthenosphere is hot enough to flow slowly. Heated rock rises‚ moves up toward the lithosphere‚ cools and circulates downward. Riding above this circulation system are the tectonic plates‚ enormous moving pieces of the earth’s lithosphere. [pic] Plate Movement Tectonic Plates move in four different ways. When tectonic plates come into contact‚ changes on the earth’s surface occur. 1. Diveregnt Boundary-

everywhere all the time. In this lab you will test the idea that microbes are ubiquitous or present everywhere at all times. Materials One Triptic Soy Agar (TSA) plate per student One sterile swab Procedure 1. Decide on an area to test for the ubiquity of microbes. List your area on the white board in front of the classroom. 2. Obtain one TSA plate and label it on the bottom (side with the agar) with your name‚ class section and the surface you will sample. 3. Obtain one sterile swab. 4. To obtain a sample

sterile cotton swab‚ sterile water in test tube‚ 4 agar plates and 2 blood agar plates‚ wax pencil and labels. Procedure: Appropriately label the cover of each plate as indicated in lab. 1. Determine 2 sampling sources‚ one from your body and one from the surrounding environment. 2. For the first agar plate‚ for sampling from air‚ remove the lids from the plate and allow it to sit uncovered for 15 minutes. 1. For second agar plate‚ open the “stick” end of the sterile cotton swabs to avoid

“The extent to which tectonic processes represent hazards depends on when and where they are experienced. Discuss” Throughout this essay I will be discussing my view on the extent to which I think tectonic processes represent hazards depending on when and where they are experienced. My view is that the hazards caused by tectonic processes such as volcanoes and earthquakes are very much likely to have a bigger impact socially‚ environmentally and economically depending on where they had occurred

Agar and Media Preparation— Agar plates containing King’s B Agar were often used throughout the experiment to support growth of Pseduomonas fluorescens. A recipe was used that included a mixture of 10g Proteose Peptone #3‚ 1.5g Potassium Phosphate Dibasic (K2HPO4)‚ 30ml 50% Glycerol‚ ~965ml water and 20g agar. The mixture‚ post- autoclave‚ was left to cool and 5ml 1M Magnesium Sulfate (MgSO4) was added and created about 40 plates. King’s B Medium was made using the same procedure as the King’s B

Earthquakes and Logarithms Earthquakes are responsible for a wast majority of natural hazards on our planet. This natural geological phenomena are almost impossible to predict‚ and they occur usually in zones of the planet that are prone to movement in the uppermost crust of the earth. Certain areas are more likely to experience earthquakes‚ and also the aftermath of the earthquakes can be just as destructive or sometimes even more. Different methods of measuring earthquakes have been implemented
