Affecting the environment Describe natural factors that have changed the surface and atmosphere of the Earth. Natural factors such as volcanic eruptions‚ changes in the Earth orbit and the amount of energy released from the Sun which can affect the Earth climate. Also human activities can be another reason why atmosphere is of the Earth is changing. When we burn fossil fuel such as coal‚ oil‚ and deforestation have caused the concentrations of heat-trapping “Greenhouse Gas” will increases significantly

1. What are the relationships among Earth’s mantle‚ crust‚ astheno sphere‚ and lithosphere? The lithosphere is basically the strong outer shell of earth. It is roughly 100km thick depending on its age‚ and is broken into plates‚ known as the tectonic plates. Within the lithosphere is the crust as a portion of the upper mantle. The crust is the outer most portion of the earth and takes up less than 1% than the total volume of the earth. It is commonly compared to the skin of an apple‚ whereas

massive eruptions have permanently altered global climate and large parts of the Earth’s topography. However the scale is only one of several factors. The impact of eruptions also depends on physical factors such as viscosity and gaseous content of magma‚ whether eruptions are effusive or explosive‚ the nature of the material erupted e.g. pyroclastic flows‚ superheated gases‚ ash‚ lava etc. There are also human factors such as prediction‚ hazard mitigation‚ and evacuation procedures‚ population distribution

PHARMACEUTICAL LOTIONS INTRODUCTION Lotions are usually liquid suspensions or dispersions. They consist of finely powdered‚ insoluble solids held in more or less permanent suspension by the presence of suspending agents and/or surfactants. Calamine Lotion (USP) is the classic example of this type of preparation. It can be prepared by triturating the ingredients into a smooth paste and then adding the remaining liquid phase. This procedure can be done manually by using pestle and mortar

------------------------------------------------- Rock (geology) In geology‚ a rock is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example‚ the common rock‚ granite‚ is a combination of the quartz‚ feldspar and biotite minerals. The Earth’s outer solid layer‚ the lithosphere‚ is made of rock. Rocks have been used by mankind throughout history. From the Stone Age rocks have been used for tools. The minerals and metals we find in rocks have been essential to

Some of the Pre-Socratic philosophers were rational and some were not. When Thales determined that the main principle element was water‚ he rationalized from his observance that the main ‘nutriment’ in all things is moist and that water is the origin of moisture. He rationalizes that heat itself is generated from moisture which he was most likely referring to humidity in the air. He observes that even our very breath contains moisture. Another point he ties together is that the world is held

Introduction The increased content of Carbon Dioxide in the air increases the warmth of our planet and is the main cause of the “Global Warming Effect”. One answer to global warming is to replace current technologies with alternatives that have comparable or better performance‚ but do not emit carbon dioxide. We call this Alternate energy. According to Oxford Dictionary‚ Alternative Energy is energy fueled in ways that do not use up natural resources or harm the environment. Alternative energy

Scientists proved by 2001 over 400‚000‚000km cubed of magma had erupted from Chances Peak since the first eruption. Also‚ since the volcano awoke‚ the only proven safeguarded area on the

Dynamic Earth Has the Earth been static since the beginning of time? Well‚ Earth hasn’t been moving vigorously but it is changing at a steady rate. New geological features‚ rock formations‚ and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn’t rest. Through the churns and molds‚ the twists and turns‚ Earth is active because of plate tectonics and the rock cycle. The ideas
