The Earth will interact tidally with the Sun's outer atmosphere, which would serve to decrease Earth's orbital radius. The Niagara Falls will continue to retreat upstream, reaching Buffalo in about 30,000–50,000 years. For example, the eccentricity changes over time cycles of about 100,000 and 400,000 years, with the value ranging from less than 0.01 up to 0.05. The flow of heat will be concentrated, resulting in volcanism and the flooding of large areas with basalt. The Sun has a large impact on the Earth and so it is also considered a part of the Earth system. The Sun was born.  This has resulted in a widespread, ongoing mass extinction of other species during the present geological epoch, now known as the Holocene extinction. But, as stated above, without surface water, plate tectonics would probably come to a halt and most of the carbonates would remain securely buried until the Sun becomes a red giant and its increased luminosity heats the rock to the point of releasing the carbon dioxide. Coastal Outputs. Once the orbit of the Moon closes to a distance of 18,470 km (11,480 mi), it will cross the Earth's Roche limit. Try to identify dangerous feedback loops.  Later, in the 1990s, Roy Livermore calculated a similar scenario.  However, animal life may last much longer since more than 50% of oxygen is currently produced by phytoplankton. These power systems required ground detection… Closed systems are closed to matter but open to energy (E.g. This means that tidal interaction with the Earth would break apart the Moon, turning it into a ring system. ... although it is possible to think of the entire universe as an isolated system. Even if sufficient oxygen were to remain in the atmosphere through the persistence of some form of photosynthesis, the steady rise in global temperature would result in a gradual loss of biodiversity. It is similar to logic gate AND. Many signal processing, communications, and controls systems are dynamic. 5.2.A2 Compare and contrast the inputs, outputs and system characteristics for two given food production systems. Smaller animals would survive better than larger ones because of lesser oxygen requirements, while birds would fare better than mammals thanks to their ability to travel large distances looking for colder temperatures.  Once the supercontinent is built, plate tectonics may enter a period of inactivity as the rate of subduction drops by an order of magnitude. At this point, trees and forests in their current forms will no longer be able to survive. A star system known as TRAPPIST-1 has three potentially Earth-like planets in its orbit. On the other hand, a global warming period of finite duration (based on the assumption that fossil fuel use will cease by the year 2200) will probably only impact the glacial period for about 5,000 years. , The Science Education Resource Center, Carleton College, offers the following description: "Earth System science embraces chemistry, physics, biology, mathematics and applied sciences in transcending disciplinary boundaries to treat the Earth as an integrated system. Earth is also considered to be more of an approximation of a closed system because … , Tectonics-based events will continue to occur well into the future and the surface will be steadily reshaped by tectonic uplift, extrusions, and erosion.  The loss of the magnetosphere will cause an increase in erosion of light elements, particularly hydrogen, from the Earth's outer atmosphere into space, resulting in less favorable conditions for life. If Earth is not destroyed by the expanding red giant Sun and the Earth is not ejected from the Solar System by violent relaxation, the ultimate fate of the planet will be that it collides with the black dwarf Sun due to the decay of its orbit via gravitational radiation, in 1020 (Short Scale: 100 quintillion, Long Scale: 100 trillion) years. , Plants—and, by extension, animals—could survive longer by evolving other strategies such as requiring less carbon dioxide for photosynthetic processes, becoming carnivorous, adapting to desiccation, or associating with fungi.  Following this event, Earth's sole legacy will be a very slight increase (0.01%) of the solar metallicity. Though it is not possible to see deep into the centre of the planet, various scientific tests and predictions such as geological samples and seismic analysis have helped to create a picture of what the Earth (and other planets) look like below the surface. He dubbed the resulting supercontinent, Amasia. The hydrosphere includes the ocean, rivers, lakes, streams, groundwater, water vapor, and even puddles. , The formation of a supercontinent can dramatically affect the environment. The Earth emits around 400 #W# / #m^2#, to which 340 #W# / #m^2# is reflected back through greenhouse gases, the rest escaped through radiation. , Once the Sun changes from burning hydrogen within its core to burning hydrogen in a shell around its core, the core will start to contract and the outer envelope will expand. The first plants to disappear will be C3 herbaceous plants, followed by deciduous forests, evergreen broad-leaf forests and finally evergreen conifers. To explore the nature of systems by examining the systems that make a bicycle work.  Such an encounter can trigger a 40-fold increase in the number of comets reaching the inner Solar System. The notion that the Earth, itself, is alive was a regular theme of Greek philosophy and religion. The higher temperature causes the remaining hydrogen to undergo fusion at a more rapid rate, thereby generating the energy needed to maintain the equilibrium. The output from the Earth's Space System is the aurora, the magnetic storms, the Van Allen belts and the many different electrical currents that flow in space near Earth and in its outer atmosphere. An uncertain factor in this extrapolation is the continuous influence of technology introduced by humans, such as climate engineering, which could cause significant changes to the planet. Most of Earth's atmosphere will be lost to space and its surface will consist of a lava ocean with floating continents of metals and metal oxides as well as icebergs of refractory materials, with its surface temperature reaching more than 2,400 K (2,130 °C; 3,860 °F). Computer simulations of the Solar System's evolution over the next five billion years suggest that there is a small (less than 1%) chance that a collision could occur between Earth and either Mercury, Venus, or Mars. The loss of mass will mean that the orbits of the planets will expand. Some time in the next 1.5–4.5 billion years, the axial tilt of the Earth may begin to undergo chaotic variations, with changes in the axial tilt of up to 90°. The four components of the Earth system interact with one another by flow of matter and energy among the reservoirs. , The loss of the oceans could be delayed until 2 billion years in the future if the atmospheric pressure were to decline. Continental drift is facilitated by two factors: the energy generation within the planet and the presence of a hydrosphere. The orbital distance of the Earth will increase to at most 150% of its current value. In a dynamic system, the values of the output signals depend on both the instantaneous values of the input signals and on the past behavior of the system. Energy radiates into the Earth’s system, mainly from the sun.  The production of heat through radiogenic processes is sufficient to maintain mantle convection and plate subduction for at least the next 1.1 billion years. The earth.html file is a page containing a link to the display of your map in Google Earth. In its report, participants noted that, "The fields that make up the Earth and space sciences are currently undergoing a major advancement that promotes understanding the Earth as a number of interrelated systems". This is expected to occur between 1.5 and 4.5 billion years from now. Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end. Earth system science is the study of how scientific data stemming from various fields of research, such as the atmosphere, oceans, land ice and others, fit together to form the current picture of our planet as a whole, including its changing climate. System objects are designed specifically for implementing and simulating dynamic systems with inputs that change over time. If this process were to continue unmodified into the future, the subduction and release would reach an equilibrium after 65% of the current ocean mass has been subducted.
