Surface

In our lab, we had to do experiments to answer the following questions: Problems: Is the frictional force greater when an object is still (static) or sliding? 2) Does the surface area of contact between two surfaces affect the frictional force? 3) Does the type of surface (carpet vs. hard/smooth surface) affect sliding friction? 4) Does the force between two objects (weight) affect sliding friction? While doing this lab, we were able to answer the given questions and we were…

different ways, either by surface mining or underground mining methods (Coal and the Environment). Surface mining is done when the coal is less than 200 m below the Earth’s surface, while underground mining is done when the coal is more than 200 m below the surface of the Earth (Coal and its Uses). Underground mining accounts for approximately 60% of the world’s coal production (Coal and the Environment). Some of these underground mines can go as deep as 1000 m below the Earth’s surface (Coal…

Priscilla Lee's "Beneath the Surface" is a poem talk about the barracuda fish that is found in tropical oceans. This journal will take a look at this poem from an ecocriticism theory point of view. In "Beneath the Surface" nature plays a major role in the poem due to the fact it the landscape can be manipulated. The landscaped cannot be manipulated or change completely due to the fact the barracuda fish is the main character. The barracuda fish is a saltwater animal and needs a tropical…

considerably as the tide recedes. Even where there is air in the sand its humidity is high, and burrowing creatures are not in appreciable danger of desiccation (J.M. Baker and W.J. Wolff, 2009). The deeper-dwelling forms are also well insulated from surface fluctuations of temperature and salinity, which seldom produce much effect below a depth of a few inches. However, many burrowing animals descend deeper in the sand during winter than in summer within temperate areas (Marinebio.net,…

Dark Web entails, there are also some fascinating facts about it. For example, did you know that it has been reported that the Deep Web itself “is approximately 400 to 550 times larger than the surface web, and also contains 7,500 terabytes of information compared to the 19 terabytes of info in the surface web? Also, the…

Introduction The urbanization of a catchment is a drastic change in land use, and has major effects on the hydrological cycle during heavy rainfall events because of its impermeable surfaces (G. E. Hollis). By recording the discharge in a catchment the data can be used to create a hydrograph. It is often useful to analyse a hydrograph because it shows how quickly rainwater moves to the stream channel (Holden J. 2012.) The aim of this study is to compare an urban and rural catchment, and to find…

In my academic experience, I have used surface learning during my whole high school in only my history classes. In these types of classes I only attempted to memorize definitions and facts so that I could pass the test or quizzes. I have never been that great with any history class or anything else that falls into the category. When people start talking about historical things I honestly feel so lost because I have no clue what they are talking about. Those types of facts never stayed in my head…

(blue methylene and water).Wet mounts are used with a piece glass concave slide and a solid object for viewing it. A drop of water or other liquid substances is dropped onto the object and a cover slip is slid on top of the liquid. The tension of the surface of the water automatically will close the cover tight to the slide while still holding the object in place for accurate, focused viewing. Dry mounts are also used with a piece of a flat slide but only with a solid object instead of dropping…

where the pesticide was applied will have the highest concentrations. As you move away from those areas the concentration should decrease. Although they can remain high due to runoff, and wind deposits. The soil depth must also be considered. The surface soil will have the highest concentration. As the pesticide leaches through the soil the…

What the stream team will be doing is going to the stream and seeing how much nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics…
