surficial "layers" as being comprised of several major realms or "geospheres": the atmosphere‚ lithosphere‚ hydrosphere‚ biosphere and pedosphere. The reference to "sphere" applies because Earth is spherical‚ and hence layers around it form somewhat spherical shells at the outermost edges of the solid planet. The atmosphere‚ biosphere and lithosphere more completely encircle Earth‚ while the hydrosphere and pedosphere tend to be more discontinuous. Figure 1.01 schematically illustrates some of the processes

Methane > Hydrosphere Methane is made two different ways in the ocean. The first is by thermogenesis‚ which is where methane is produced on the seafloor when organic material is broken down by heat. The other is Biogenic‚ which is where microorganisms eat organic material and leave behind methane as a waste product. ("Methane in the Ocean") There are large amounts of frozen Methane in the Arctic Ocean. ("Methane Emissions from the Arctic Ocean: Image of the Day") Methanogenic bacteria survive in

Hydrological process operating within the Narrabeen Coastal environment The hydrosphere refers to the interconnected system of water storage in the atmosphere and lithosphere‚ including the oceans‚ ice caps‚ rivers and groundwater. Narrabeen is a beachside suburb and is highly influenced by the hydrosphere. Processes involved in the hydrosphere are water‚ salinity‚ temperature‚ waves‚ tides and current. Longshore drift is a major process operating within the

things such as rocks‚ soils and water. It is the symbiosis between the physical environment and the biological life forms within the environment. The biophysical environment is made up of four overlapping spheres: Atmosphere‚ lithosphere‚ hydrosphere biosphere. As shown in figure (1). These four spheres are dependent upon each other. Each sphere plays a vital role in sustaining life on earth.

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 (or transferred) between these various reservoirs by a variety of natural and anthropogenic (human)

Earth also has its own life support system which includes the atmosphere‚ hydrosphere‚ lithosphere and biosphere. Air & Protection Both the earth and spaceships provide air and shelter by themselves. The atmosphere is the layer of gases that surround the Earth roughly 1000km thick. The atmosphere provides the air that we breathe

Biosphere is defined as that part of the earth and atmosphere in which many smaller ecosystems exist and operate. Three main subdivisions of the biosphere are lithosphere (solid matter); hydrosphere (liquid matter)‚ and atmosphere or the gaseous envelope of the earth which extends up to a height of 22.5 km. The area of contact and interaction between these components is really important for life‚ for it is here that the entire life is confined and the basic processes of life like photosynthesis and

HYDRO-ECOSPHERE Hydro-ecosphere is considered as a more suitable habitat for microorganisms than the atmosphere and lithosphere‚ mainly because hydrosphere contains water‚ which is important in microbial metabolism (Atlas and Bartha‚ 1993). The unique properties of water are also attributes of hydrosphere as a suitable habitat. Due to polarity of water (slightly negative and slightly positive)‚ water is considered as a great solvent‚ capable of forming hydrogen bonding. Large heat
