1. What transitions has Earth gone through and why? The young earth was anything but habitable. Radioactive elements decaying within its mass and impacts from debris raining down form space generated intense heat. There was no life during this era. Is called the Hadean era and was formed about 4.5 billion years ago. Hadean comes from the Greek word Hades which means “Hell”. That’s how hot the Earth’s temperature was. The next phase in the Earth’s history was the Archean era. It existed

Evolution‚ the belief that all humans were made from earlier forms of history in the Earth that leaves people in a true controversy over what to believe. Inherit The Wind is a play revolving the Scopes Monkey Trial‚ where a school teacher‚ Bertram Cates‚ taught evolutionism to his students without being allowed. He is then accused and brought to trial where many people come to join in the fight. Brady‚ a lawyer‚ has the job in the play to prosecute this “lawbreaker” while putting up a strong personality

when the atmosphere and environment were different to those presently found on earth Archaea are single cell micro-organisms with no nucleus‚ it use anaerobic respiration (able to living in the absence of Oxygen) and live in extreme environment/condition such as high temperature‚ acid-rich‚ saline area etc. those environment are rich in minerals but hazardous to other organisms. Archaea’s population decreased after earth filled with oxygen‚ other than that‚ current archaea is very same as ancient

A speech for Mother Earth. We are all human beings. All people‚ You‚ me‚ our neighbors. No matter where You live in this world‚ if it is in Africa or South-America‚ if it is in Asia or Europe‚ Australia or North-America‚ we are all sisters and brothers in humanity. All people of the world. Whether rich or poor‚ whether color‚ religion‚ culture or political conviction‚ we are all residents on this one planet‚ our home - Mother Earth.

Scientists have studied forests and fires to determine the secret of Nature’s success in attaining this necessary balance. They have learned that a "natural" fire results from a certain fuel condition. Some forest types produce and accumulate fuels faster than others; some decompose fuels more readily than others. However‚ at some point in time‚ every forest type has fuel of the right quantity and quality for that forest to be "ready" to burn. In the past‚ forest fires would benefit the whole forest

Evolutionists in Inherit the Wind Inherit the Wind by Jerome Lawrence and Robert E. Lee‚ written in 1955‚ is an exceptional play that depicts the events of the Scopes Trial in 1925. The Scopes Trial or “Monkey Trial” was held in Dayton‚ Tennessee. Previous to the trial‚ the Butler Act was passed in Tennessee to ban the teaching of evolution. In an attempt to test the law‚ high school teacher John Scopes taught the theory of evolution to his class. After violating the act‚ Scopes was taken to

the first and upper most layer of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This layer is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest layer by far. Mantle is like silly putty consistency. It is the largest layer of Earth sitting under the Crust. It is made

Global Wind The region of Earth receiving the Sun’s direct rays is the equator. Here‚ air is heated and rises‚ leaving low pressure areas behind. Moving to about thirty degrees north and south of the equator‚ the warm air from the equator begins to cool and sink. Between thirty degrees latitude and the equator‚ most of the cooling sinking air moves back to the equator. The rest of the air flows toward the poles. The air movements toward the equator are called trade winds- warm‚ steady breezes
