How to choose your surfboard? From another point of view the surfboards are tools‚ in school we have a variety of surfboards for different levels and surfers. It’s like choosing shoes‚ first you look for size and if you want to run fast looking for a light and tight sports‚ if you want to go for hard surfaces like mud you want a thick boots and grip. There are boards of all kinds and forms because‚ quite possibly beyond surfers of all kinds. ///The choice of a surfboard is directly related to

EOSC 114: Volcanoes Notes from Web Notes Lesson 1: Why Do Volcanoes Have Different Characteristics? A. Formation of Lava Magma is formed by melting preexisting rock in Earth’s interior For magma to rise through crust it must be: (1)less dense than the crust (2) runny enough to flow (3) hot enough to stay liquid Magma that cools to form solid rock = lava B. Composition of Magma/Lava Magma is composed of various proportions of: Oxygen‚ Silicon‚ Aluminum‚ Iron‚ Calcium and Potassium Mineral –

nailbility and lessened the dead weight. It is lighter than the conventional concrete. The use of lightweight concrete has been widely spread across countries such as USA‚ United Kingdom and Sweden. The main specialties of lightweight concrete are its low density and thermal conductivity. Its advantages are that there is a reduction of dead load‚ faster building rates in construction and lower haulage and handling costs. Lightweight concrete maintains its large voids and not forming laitance layers or cement

Many people think of scuba diving as just a swim in the water‚ but in reality it is a very exciting‚ dangerous‚ and potentially fatal sport and activity. There are many types of scuba diving‚ ranging from recreational to sport to career diving. Scuba Diving is just not a swim in the water‚ scuba requires certification‚ uses technical equipment‚ and there is a lot of risk involved with scuba diving. Scuba‚ which is actually an acronym for "self-contained breathing apparatus"‚ Allows

eruption‚ three predominate: the buoyancy of the magma‚ the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. What follows is a brief description of these processes. As rock inside the earth melts‚ its mass remains the same while its volume increases--producing a melt that is less dense than the surrounding rock. This lighter magma then rises toward the surface by virtue of its buoyancy. If the density of the magma between the zone

PD Assessment Biomechanics in cricket There are lots of different aspects that make up biomechanics they are force‚ motion‚ balance/stability and fluid mechanics. All of these aspects of biomechanics affect you when you’re playing cricket. Force can be defined as a pushing or pulling action that causes a change of state of a body. In biomechanics any force exerted by one part of the body on another is known as an internal force‚ whereas all other forces are external. Getting balance is very important
