Marine Ecosystems are the largest systems on the planet‚ covering over 70 percent of the Earth’s surface and constituting over 99 percent of the living space on the planet (area x depth). These vast ecosystems are composed of many different habitats which extend from the near shore regions to continental shelves and the deep ocean. They are home to millions of species and provide food‚ income‚ protection‚ and many other vital ecosystem services to billions of people around the world. ECOLOGICAL

Weathering & Erosion Weathering is the process that produces change in the surface of rocks exposed to the atmosphere and/or hydrosphere. Physical weathering is breaking rock by force. ex: hitting‚ scratching‚ cracking Frost action (AKA ice wedging)- Water seeps into small cracks in rocks. When the water freezes it expands creating great pressure. The crack widens and allows water to seep deeper into the rock. (Robert Frost’s Mending Wall makes a reference to a frost heave

Creating a Healthy City Dr. Casey Price BIO2000 – Environmental Health What Would a Healthy City Look Like A healthy city would be filled with clean air and a safe and high quality environment‚ with all basic needs such as water‚ food‚ and shelter for all residents. There would be ample education supplied for everyone‚ and in turn diverse employment opportunities so that more residents will have jobs. A healthy city would have plenty of recreational areas for its residents‚ and a public transportation

The study states two different split method transportation approaches to a Mars Mission: SEP-Chem and Hybrid. Compare and contrast them. State the approach you favor and why. In the Evolvable Mars Campaign the two transportation methods investigated are SEP-Chem and Hybrid. Similarly‚ they both use split methods combining solar electric and chemical propulsions to escort man on a mission to mars‚ and back to Earth. Even though‚ they both can provide the extraordinary ride it’s their unique

About 71% of the surface is covered by salt water oceans‚ with the remainder consisting of continents and islands which together have many lakes and other sources of water that contribute to the hydrosphere. Earth’s poles are mostly covered with ice that is the solid ice of the Antarctic ice sheet and the sea ice that is the polar ice packs. The planet’s interior remains active‚ with a solid iron inner core‚ a liquid outer core that generates the magnetic

evidence every day‚ it is assumed that there is indeed a mass extinction happening on our planet today. As the carbon dioxide levels are increasing‚ oceanic anoxic events are just the earth’s response to excess carbon dioxide into the atmosphere and hydrosphere. In extreme cases‚ anoxic events can lead to mass extinctions of marine organisms because there is less oxygen in the oceans. During the Cenomanian-Turonian boundary event‚ the earth’s oceans lacked oxygen for nearly half a million years‚ causing
