Imagine looking in ~ a puzzle piece and trying come make feeling of it. You might be able to make out the snapshot that is on it. In ~ the really least you have the right to make out the colors and shapes. However imagine the you were able come fit the piece right into a bigger puzzle, figure out exactly how it is connected to different shapes, and assist us recognize a larger picture. It is analogous come the procedure of considering planet as an integrated system instead of secluded parts. It allows us to check out our planet in a brand-new way.

You are watching: Earth is considered a system because all of its parts

During the 1980s, satellites began to enable us to look at earth from a an ext removed perspective. And also scientists uncovered that the components of our world we had actually been looking at up nearby – like forests, clouds, the ocean, glaciers, exploding volcanoes, and eroding rocks – were all connected. “From space we deserve to view the earth as a totality system, watch the net results of facility interactions, and begin come understand just how the planet is an altering in an answer to natural and human influences,” NASA described in a 2003 report (see longer excerpt below.) v the satellite data and also high-tech sensors ~ above land and in the ocean, we are obtaining a sense of the larger puzzle. Researchers room discovering just how their pieces of the puzzle are related to other pieces. These relationships between the puzzle pieces and also the bigger puzzle are interesting to people occurring models the the planet system, too. They hoped to describe as lot as possible of how planet worked through complicated mathematical equations to make models as specific as possible. And over the last couple of decades, they have been able to make earth system models much an ext accurate together we have learned around interactions the the system.

The sum of that Parts

The parts of the earth system space often described as "spheres" - the atmosphere, hydrosphere, biosphere, cryosphere, and geosphere. Boy name Ruzek notes the “the difficulty with any type of representation the divides the device is the risk of proceeding a deconstructed tardy of the holistic earth system - in reality no part of the planet system have the right to be thought about in isolation from any type of other part.” once considering the components of the planet system, the is necessary to not shed track that the interactions between parts the the system.

While no technically ~ above the planet, the sunlight is a crucial part of the planet system too. Sometimes referred to as component of the exosphere (all space-related phenomena that impact Earth), power from the sunlight drives processes of the planet system.

Bringing the earth to the great

While the components of the planet system (air, water, land, life, and also ice) connect in assorted ways, they room traditionally covered individually in science classes. Often they are different chapters of planet science textbooks or in different textbooks altogether. Because that example, life is regularly not a component of earth science classes in ~ all. The division of scientific disciplines into chemistry, physics, and biology, deserve to be a an obstacle to teaching around Earth together an integrated system.

Despite the challenges, many locations of science education are moving towards fostering student knowledge of the connections in between different components of the planet. Earth system scientific research provides methods to discover interdisciplinary science and ways to integrate the natural and also social sciences, arts, and culture. According to education Martin Ruzek in his essay Earth system Science in a nutshell (which have the right to be found on the beginning Point: teaching Entry-Level Geoscience website), “Earth system science offers natural methods for combining research and also education, and promotes inquiry right into the complicated world roughly us. The vast perspective that planet system science provides promotes one inclusive strategy to student interest - there is something for everyone.”

The earth System and also Climate Change

As the climate proceeds to warm, the planet system changes. The ice of the cryosphere melts, sea level rises, and weather patterns and also ecosystems change. And also as the earth system changes, the climate warms. Several of these changes even amplify the rate of an international warming. A great way to highlight the interconnections in the earth system with students is by exploring the factors that affect and are affected by earth climate.

“Given the concerns that mankind is impacting the Earth"s physical climate system, a wider concept of planet as a device is emerging, consisting of societal dimensions and also the recognition that humankind plays one ever-increasing role in worldwide change. In ~ this concept, knowledge from the classic Earth science techniques (geology, meteorology, oceanography, ecology, biologic ...) is being gleaned and also integrated to kind a physical basis for planet System Science,” claims Ruzek.

Ruzek proceeds by saying, “Earth system science fosters the synthetic of disciplinary knowledge right into a holistic version of planet with more comprehensive interdisciplinary relevance. However, the advance both conceptually and also physically the the planet system model and its quantitative assessment in the classroom and laboratory is a continuing, formative processes which requires nurturing and commitment to eclectic learning beyond one"s discipline. The intersection that disciplinary specialties regularly provides the many fertile and also interesting areas for study, yet is quickly sidetracked by classic disciplinary interests.”

NASA"s meaning of planet System Science

“Earth is the just planet we understand of the sustains life. Life on earth is critically dependence on the abundance of water in all three phases - liquid, vapor, and also ice. Carbon, currently in a variety of forms, is the very basis the life, and also its biggest reservoir. In the atmosphere, carbon totally oxidized as carbon dioxide, completely reduced as methane, and in particulate form as black color carbon soot produces the greenhouse impact making planet habitable. Earth"s atmosphere and also electromagnetic field safeguard the world from harmful radiation while allowing useful radiation to reach the surface and also sustain life. Planet exists in ~ the Sun"s zone of habitation, and also with the moon, maintains the specific orbital inclination necessary to produce our seasons.

These remarkable components have contributed to earth maintaining a temperature range conducive come the development of life for billions of years. The an excellent circulation systems of planet - water, carbon, and the nutrients-replenish what life needs and assist regulate the climate system. Planet is a dynamic planet; the continents, atmosphere, oceans, ice, and also life ever-changing, ever interacting in myriad ways. These complex and interconnected processes comprise the planet system, which creates the communication of the scientific research study and room observation the we refer to as earth system science.

In planet system science, researcher take a contextual strategy to scientific inquiry - lock explore excessive weather occasions in the context of transforming climate, earthquakes and also volcanic eruptions in the paper definition of tectonic shifts, and also losses in biodiversity in the context of changes in Earth"s ecosystems. This leader to the exploration and discovery the causes and effects in the environment. Because that instance, planet system scientists have connected ocean temperatures and circulation come the moderate climate of north Europe loved one to its latitude, the yearly changes of ozone concentration over Antarctica with the production of commercial refrigerants in the northern Hemisphere, and also the physics and chemistry the the atmosphere to air quality and fresh water availability.

From space, we deserve to view the planet as a totality system, watch the net results of complicated interactions, and also begin come understand exactly how the world is an altering in solution to natural and also human influences. Because that example, earth system scientific research has started to understand and quantify the impacts of "forcings" ~ above the climate system developed by the Sun"s solar variability and the atmosphere"s boosting concentrations that carbon dioxide and also aerosols. The reality that researchers detect not simply variability however trends in the vital measures of planet systems do it command for united state to ask, "How is the planet system changing, and also what room the after-effects for life ~ above Earth?"
