What is Marine Ecology? Marine Ecology is the scientific study of marine-life habitat‚ populations‚ and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment). Marine ecology is a subset of the study of marine biology and includes observations at

the ability of an ecosystem to adapt to a changing function and structure following an episode of natural or human induced stress. The biophysical interactions between the hydrosphere‚ lithosphere‚ atmosphere and biosphere lead to diverse ecosystems. Through the interaction of the three nonliving spheres‚ the hydrosphere‚ lithosphere and atmosphere a variety of different conditions are created for the biosphere. Location of a ecosystem determines the characteristics of the nonliving spheres it

It is also the earth solid sphere consisting mainly of massive rocks. The massive rocks form large land masses called continent and small island groups . Different land form such as mountains‚hills‚valleys‚plateaus and plains make up the lithosphere. The hydrosphere include all water forms such as oceans‚seas‚rivers‚lakes‚and groundwater

Lesson 13.6 HOW WAS THE PHILIPPINE ARCHIPELAGO FORMED? In 1912‚ Alfred Wegener proposed the past existence of a supercontinent called Pangaea (or Pangea). According to Wegener‚ Pangaea had split apart into a northern half called “Laurasia” and a southern half called “Gondwanaland”. Surrounded by a global ocean called “Panthalassa” and separated by a big body of water called “Tethys Sea”. The slow drifting of continents has been occurring over the past 250 million years. In the 1960s‚ the theory

Hydraulic Fracturing Over the past few decades‚ the United States has become heavily reliant on using nonrenewable resources. The excessive uses of these resources‚ such as coal‚ are extremely harmful to the environment and can be considered responsible for global climate change and the destruction of a once healthy atmosphere. Some companies have claimed to find a “clean” source of energy called natural gas‚ found deep within the Earth’s crust. Commercials created by these companies state that
