Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles

rock cycle operates. How do rocks metamorphose at destructive plate boundary? Rock cycle is a cycle that describes how rocks are transformed. Igneous rock can change into sedimentary rock or metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Besides‚ metamorphism at the destructive plate boundaries creates different characteristics of rocks. Operation of the rock cycle The Rock Cycle

WATER CYCLE Water Cycle‚ also known as hydrologic cycle‚ is a process that is constantly recycling the Earth ’s supply of water. This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called

Topic 9 - The Carbon Cycle Aspects of the carbon cycle are similar to the hydrologic cycle because both are good examples of “Interactions between the systems". Textbook – topic not covered in text. http://www.windows2universe.org/earth/ The Carbon Cycle Neglecting the small amount of carbon (C) added to Earth by meteorite impacts‚ there is a fixed amount of carbon on Earth (~800‚000 billion tonnes). All living things are made of carbon but carbon is also a part of the ocean‚ air‚ and

CYCLE OF THE INFANTRYMAN by LCPL BACH‚ GEORGE The Cycle of the Infantryman applies to fire and maneuver for a combat element. For example purposes the buddy team will be our combat element and a static enemy position (e.g. bunker) will be the target. The phases of the cycle are SHOOT‚ ASSESS‚ MOVE‚ AND KILL. The cycle may loop until there is no longer an enemy threat or until target position is gained. The following is a break down of each phase. -SHOOT During this phase of the cycle a base of

Elena Chen CH 221-227 November 3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into

Carbon Cycle Living organisms are significant in the recycling of numerous elements contained in an ecosystem. One of the elements is carbon. Carbon is nonmetal‚ forms over ten million different compounds‚ found in minerals‚ oceans‚ and is the main component of biological compounds. So how do living organisms and their biochemical reactions contribute to the recycling of carbon? Carbon moves through the ecosystem in a cycle‚ in which the living organisms take and release

The Main Parts of the Water Cycle The main parts of the water cycle are evaporation‚ condensation‚ and precipitation. They go together in a circle/cycle called the water cycle. None of these parts can be missing. (Well‚ everything in the water cycle is needed.) Evaporation- Evaporation is when water turns into water vapor and flows up into the sky. You can’t see it because it’s now gas and gas is invisible. Evaporation usually happens on hot‚ rainy days because the sun’s energy
