the organism. Q: Based on the conditions of early Earth‚ what conclusion can you draw about the amount of anaerobic respiration that was occurring at Earth’s beginning? Explain your answer. A: The atmosphere of early Earth was made up with almost of different nitrogen gases‚ water vapor and carbon dioxide. There wasn’t any pure oxygen or I should say there wasn’t any breathable oxygen in the air in those days. The first form on earth had to develop in the absence of oxygen using the anaerobic

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

Save the Earth With all the talk about going green‚ it seems much easier to let the cards fall where they may. What’s easier? Just throwing all the trash into one can‚ or sorting it into separate cans? As hard as it could be to clear the mess that this and past generations have left‚ it would be severely healthier than the alternative. Plutonium is a dangerous toxin that is released from nuclear power plants. “Plutonium‚ which has the half-life of only 0.5 million years‚ but is so toxic that

There are many different layers within the Earth. The core is at center of the Earth. The Earth’s core takes up sixteen percent of Earth’s volume‚ containing thirty-three percent of its Mass ..Pressure rises steadily inside the earth because of the weight of overlying rock. Therefore ‚the Pressure at the outer boundary of the core reaches 1.37 million atmospheres‚ 3.7 million Atmospheres. The core is made mostly of iron and nickel and possibly smaller amounts of lighter elements including sulfur

“EARTH HISTORY” Geologic Time: Geology needs a time Scale: -The prime goal of the science of geology‚ is to interpreting earth history. Geological time scale- -Anordered‚internallyconsistent‚ internationally recognized sequence of time intervals‚ and record the life of Earth. Short history of geology: James Ussher(mid 1600s)- he determined that earth was only a few thousands of years old having been created in 4004 b.c Catastrophists(17-18cen.)-believed that earth landscape had been developed
