Earth Systems Interactions
the biosphere, which contains all of the planet's living organisms, and while water (hydrosphere) often flows through the soil (lithosphere). Understanding the interactions among the earth's spheres and the The examination of the interactions is accomplished by asking oneself the following questions. The ground beneath your feet also interacts in characteristic ways with the other spheres. Life can flourish on some parts of the geosphere, but it cannot survive. One of our key questions. Ever since, interactions between the ocean's geosphere and biosphere have played a key role in the evolution of Earth. In research.
At first, the oceans and the lands were teeming with large numbers of a few kinds of simple single-celled organisms, but slowly plants and animals of increasing complexity evolved. Interrelationships developed so that certain plants grew in association with certain other plants, and animals associated with the plants and with one another to form communities of organisms, including those of forests, grasslands, deserts, dunes, bogs, rivers, and lakes. Living communities and their nonliving environment are inseparably interrelated and constantly interact upon each other.
For convenience, any segment of the landscape that includes the biotic and abiotic components is called an ecosystem. A lake is an ecosystem when it is considered in totality as not just water but also nutrients, climateand all of the life contained within it.
A given forestmeadow, or river is likewise an ecosystem. One ecosystem grades into another along zones termed ecotoneswhere a mixture of plant and animal species from the two ecosystems occurs.
A forest considered as an ecosystem is not simply a stand of trees but is a complex of soilairand water, of climate and minerals, of bacteria, viruses, fungi, grasses, herbs, and trees, of insects, reptiles, amphibians, birds, and mammals. Stated another way, the abiotic, or nonliving, portion of each ecosystem in the biosphere includes the flow of energy, nutrients, water, and gases and the concentrations of organic and inorganic substances in the environment.
The biotic, or living, portion includes three general categories of organisms based on their methods of acquiring energy: Aquatic ecosystems are those involving marine environments and freshwater environments on the land.
Terrestrial ecosystems are those based on major vegetational types, such as forest, grasslanddesertand tundra.
Earth System Science
Particular kinds of animals are associated with each such plant province. Ecosystems may be further subdivided into smaller biotic units called communities.
Earth science also known as geoscienceis an inclusive term for all sciences related to Earth geology, meteorology, oceanography, etc. Although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm. The geosphere consists of the core, mantle and crust of the Earth. The hydrosphere contains all of the solid, liquid and gaseous water on Earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found.
Ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields. Although the four systems have their unique identities, there is substantial interaction between them.
Environmental scientists study the effects of events in one sphere on the other spheres. Increased turbidity of stream water can have negative impacts on the plants and animals that live in it hydrosphere biosphere.Earth's 4 Spheres for kids/4 Major Spheres of Earth
Earth system science is conducted by examining each event sphere and sphere sphere interaction; this approach is referred to as an "Earth system science analysis" or an "ESS analysis. How may each of the earth's four spheres hydrosphere, atmosphere, lithosphere, and biosphere have caused the event to occur? The answers to this question are the sphere event impacts. What are the effects of the event on each of the earth's four spheres hydrosphere, atmosphere, lithosphere, and biosphere?
The answers to this question are the event sphere impacts. When you do an ESS analysis, you will list the answers to Questions 1 and 2 together under event sphere interactions. What are the effects of changes in one of earth's four spheres hydrosphere, atmosphere, lithosphere, or biosphere on each of the other spheres hydrosphere, atmosphere, lithosphere, or biosphere? The answers to this question are the sphere sphere interactions. This approach of answering the questions above is performed during every ESS analysis; simply replace the term "event" with the event you wish to investigate.
This forest fires event occurred in and destroyed tremendous areas of the park.
Below are some of the event sphere interactions discovered during an ESS analysis of the Yellowstone forest fires event:
