Most people don’t know that even though Hawaii is only 0.2% of the United State’s land mass‚ it has 25% of its endangered species. The Hawaiian islands have more endangered species than anywhere else in the world. Currently‚ there are ninety-seven extinct native Hawaiian plants. This paper will cover the history‚ effects‚ and the solutions to protecting native Hawaiian plants. It all started in the 19th century‚ when white settlers came to the Hawaiian Islands. When they arrived‚ and brought

All living things are made of carbon but carbon is also a part of the ocean‚ air‚ and even rocks. Carbon is present in different forms in several different reservoirs of the Earth System: Lithosphere: Carbon-rich minerals of the mantle‚ crust‚ sediments‚ fossil fuels. Biosphere: Cellular structure of plants and animals on land and in the oceans. Hydrosphere: Dissolved and particulate carbon of the oceans. Atmosphere: Gases (primarily CO2 and CH4) and aerosols (dust particles). Carbon is exchanged

Earth History (Geological Timeline) Lecturer Dr. Sameh Abu El Soud History of Early Geology Catastro‐phism Tries to explain the presence of everything on earth and their composition by catastrophes. E.g. A catastrophe happened to dinosaurs 80 million years ago. A comet fell on earth surface leading to volcanoes‚ leading to dust clouds in the atmosphere‚ preventing solar rays penetration ‚ the plants died and then the dinosaurs. Uniformi‐tarianism (James Hu on‚ late 1700s) ‐ He proposed that the

The aim of this essay is to compare the extent of human and natural forces on the formation and retention of two different coastal villages along the North Norfolk coastal zone. NATURAL FORCES ALWAYS ACT….This essay will be evaluating the different coastal management CHOICES measures and how they have impacted the changing coastline‚ and the different elements influencing the choice of coastal protection methods. The coast is the area between the land and the sea. Depending on the elements visible

4Cl2(g) + 5H2O(aq) → 2NaHSO4(aq) + 8HCl(aq) a. Which is the limiting reactant? b. What mass (in g) of the excess reactant remains after the reaction? c. What is the theoretical yield (in g) of NaHSO4? IV. FINAL BOSS! A 25.00 g sample of deep-sea sediment was collected and it was found that 12.56% of it was equivalent to the weight (in g) of pure‚ solid S8. The S8 in the sample was then treated with 150.0 mL of 1.210M HNO3 to produce aqueous SO32- and gaseous NO. 1. What is the balanced redox reaction

greatest story helped shape geology and the formation of our Earth. During chapter one‚ also known as "Buddha’s Dam‚" Montgomery visited Tibet‚ where he found flat-topped terraces standing high above river-level terrain. These terraces indicated lake sediment‚ where he later developed an image of two lakes‚ one higher than the other. Montgomery’s model was strengthened by carbon dates of 10‚000 BCE and 800 AD for

Through the years humans have evolved beyond our expectations‚ while this is exciting we have caused damage and deterioration to our environment. From the air we breathe to the water we drink and the animals we consume‚ the environment is constantly being affected. First the very stuff we breathe

crystallizing… What is the earth made of? Sediments can form from pre existing rocks‚ they collect and undergo a process called lithification‚ then form layered rocks The crust of the earth is largely covered up with sedimentary rocks When sedimentary rocks melt they become magma. Magma can undergo crystallization‚ forming igneous rocks (intrusive or extrusive) The igneous rocks may encounter rain and start to break apart and become sediments. Metamorphic rocks are formed by igneous or sedimentary

development‚ by 1980 more than half of those had been destroyed. Wetland destruction is becoming a huge problem. Not only are wetlands disappearing but those still existing are suffering degradation from chemical contamination‚ excess nutrients‚ sediment‚ and deposits from the air. Ongoing development poses the greatest threat to wetlands today. Much of Florida is affected by the loss of wetlands. Protecting them is a challenge because seventy four percent of wetlands are on private property
