In the article “Why Ancient Earth Was So Warm” the key point was to explain why early earth was as warm as it was‚ without a strong sun. The researchers‚ Eric Wolf and Brian Toon‚ go on to explain that the sun was about 70-80 percent as bright as it is today. So it would not warm the earth as much. That was then named the faint young sun paradox. The article then explains how the two greenhouse gases carbon dioxide‚ and methane could have trapped heat in the atmosphere. This would have all been

CGC ID 1-01 Park‚ Hyeon Woo March‚ 4th 2013 Documentary: How Many People Can Live on Planet Earth? 1. Why is our Human population increasing super fast? Our human population is increasing very fast due to two important factors. One of them is that there are many young people that want to create their own children‚ therefore creating high birth rates. Another factor affecting population is declining death rates. With the modern day technology and innovations‚ death rates are

A Ripple of Change Violent storms‚ rumbling earthquakes‚ tsunamis‚ and a global change in climate are some of the signs that we are about to enter the so called “changing world” – a world that is full of mystery‚ full of sorrow‚ and full of obstacle that the humankind is endanger for its existence. But if we look back to the recent years‚ the world is not like this. It is full of joy‚ abundant in its resources‚ and above all‚ our life was not at risk. This only proves that the world is so unpredictable

Washington state erupted in 1980‚ it was the biggest eruption in the United States ever recorded. It also changed the earth’s surface immensely. There are many Geo processes on the Earth because it is in constant motion‚ so the Earth’s surface is always changing; three Geo processes that change the surface of the Earth most are volcanoes‚ tsunamis‚ and earthquakes. Importantly‚ volcanic eruptions are caused by changes in the Earth’s crust. Just outside Rome‚ there are volcanic hills called Colli

The earth doesn’t have an even balance of heat and the reason for this is because the earth is a geoid ‚ the sun’s rays hit directly on the equator(caused by unequal insolation due to three factors: angle of strike‚ atmospheric depletion and surface area.) and then move outwards towards the polar areas. The atmosphere together with the ocean currents work hard to try and even out the imbalance of heat energy by redistributing the air from the equator to the Polar Regions but also from the Earth’s

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

most recent inquiry into climatic change during the ice age and it ’s possibility of reoccurring is the Snowball Earth Hypothesis advanced by Paul Hoffman of Harvard University. Snowball Earth Suggest that before the Ice age‚ continents ice free at the poles enhanced the reabsorption of carbon dioxide through erosion of silicate minerals‚ reducing the greenhouse effect making the earth colder until it reached a runaway point. This effect is Hoffman calls albedo‚ when the atmosphere becomes so cold

all of humanity thought the earth was flat. But it didn’t start that way; all it took was one man to say the world was flat‚ and no one disputed him. No scientific experiments were conducted to test the accuracy of his statement. Instead everything was based on hearsay and physical observation. But the world has evolved‚ into a place where nothing can be taken for face value. But the question is‚ how the world went from thinking the earth was flat‚ to knowing the earth is and always has been- elliptical

ALKALINE EARTH METALS what are alkaline earth metals? Alkaline earth metals are elements that are in the second group of the periodic table. the elements have two electrons on the outermost shell. the elements include Beryllium‚ magnesseum‚ calcium‚strontium‚ barium and Radium.The alkaline earth metals are all silvercolored and soft‚ and have relatively low densities‚ melting points‚ and boiling points. In chemical terms‚ all of the alkaline metals react with the halogens to form the alkaline earth metal halides
