5.3.3 ELECTRICAL ENERGY a) Design‚ construct and draw circuits containing a number of components- (globe‚ closed switch‚ open switch‚ ammeter‚ voltmeter‚ battery or transformer) What is electricity? A form of energy resulting from the existence of charged particles either statically as an accumulation of charge or dynamically as a current. What is a conductor? Materials that permit electrons to flow freely from atom to atom and molecule to molecule. An object made of conducting material will

Chapter 1 1.1 Earth Science & the Earth System -Earth science is the study of Earth and the processes that shape it -The earth system is composed of four principal components: atmosphere (air‚ weather)‚ hydrosphere (water‚ ice)‚ biosphere (plants‚ animals)‚ and geosphere (land‚ rocks). - Earth science can be broadly defined as the investigation of interactions among the four parts of the earth system. - The second largest earthquake ever recorded buckled the seafloor west of Sumatra‚ Indonesia

Ecosystems At Risk Reefs are important ecosystems as the are home to an immense amount of biodiversity and are essential in the cycle of life The Role of the Atmosphere Many reefs are located in the cyclone zone due to the necessary conditions they require to grow. For as long as reefs have existed they have been shaped by cyclones and intense storms. The severity of the storms and cyclones is determined by the length and intensity of the storms‚ which determines how much damage will be inflicted

Energy For The Future John Hosking We live in a world where technology has outgrown us‚ and where we have outgrown our world. Beyond our dependence on the earth’s resources for simple necessities we have grown dependent on it for energy. Since we developed our need for energy the quest to find it has been perpetual. Over the last 200 years that need has been mainly supplied by fossil fuels‚ predominately coal. Recently‚ interest in the development for more sustainable energy options has

The atmosphere comprises the gaseous envelope surrounding Earth. The hydrosphere consists of oceans‚ rivers and streams‚ lakes and ice in glaciers and ice caps (the latter is sometimes termed the cryosphere). The biosphere consists of all living organisms and their dead remains. Some compartments (smaller parts of a system)

Carbon is cycled and maintained a stable concentration in the through the earth’s lithosphere‚ atmosphere‚ hydrosphere‚ antrosphere and biosphere undergoing varies of reactions. As they are linked together‚ changes in any carbon reservoirs directly and indirectly could bring changes in the others. The changes or excess emissions of Carbon could give effects to the

An ecosystem at risk is both vulnerable and resilient to natural stress and human induced modifications. Discuss this statement. • Relationships between natural and human-induced modifications and the vulnerability + resilience of ecosystems at risk • Issues related to the vulnerability and resilience of ecosystems at risk • Case study (GBR) with illustrative examples • Sustained‚ logical and cohesive response The Great Barrier Reef (GBR) is an ecosystem at risk that is both vulnerable

Biotic Components: Living things constitute the biotic component of the biosphere. Abiotic Components: The air‚ the water and the soil form the non-living or a biotic component of the biosphere. The air is called the hygrosphere‚ the water is hydrosphere and the soil is called lithosphere. Air Air is a mixture of many gases like nitrogen‚ oxygen‚ carbon dioxide and water vapour. All living beings need oxygen to break down glucose molecules and get energy for their activities. This results in the
