Chapter 1 Section 1 . What Technological advances led to the rise of earth system science? Satellites such as Landsat . What is a system? A system is a kind of model , System can be defined as a part of the universe that can be studied separately. Compare and contrast an open system and ans a closed system use a Venn diagram. A closed jar of tea exchanges only energy with its surroundings, A open jar of tea exchanges both energy and matter with its surrounds, They both have Energy in from Sun and Energy out out of the jar. Why do scientists consider earth an essentially closed system? Because earth receives radiant energy from the sun and reflects much of it back in to space. Critical thinking : As the human population expands what might be some of the most important issues policymakers face ? School Recycling Science Earth system.

Essay on Nutrients and Global Systems

Within the boundary of earth is a collection of four interdependent parts known as ‘spheres’. These four parts include the Lithosphere, Hydrosphere, Atmosphere and Biosphere. The Lithosphere The Lithosphere is made up of the crust and upper mantle of the Earth. The Lithosphere can be broken into several Continental and Oceanic Tectonic Plates. These are known as Lithospheric plates. Continental and Oceanic Tectonic Plates differ within their size and composition. The effect of the different…

Lithosphere and Hydrosphere – EST supplement 1. Buffering Capacity p. 193– soil’s ability to resist changes in its PH when acidic or alkaline compounds are added to it. (plants adapt between PH of 6-7; conifers prefer more acidic soil.) 2. Permafrost p. 194– is ground whose temperature has been 0° C or lower for at least 2 years. (50% of Canada covered in permafrost; in certain regions, the top layer called active layer thaws for growing then the ground later freezes again). 3. Pollution…

abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development and evolution. The biophysical environment is made up of four components, the lithosphere, biosphere, hydrosphere and atmosphere. The atmosphere is one component that has many intricate features and characteristics that affect the rest of the Biophysical environment. The way these components interact with each other determines how the local and global environments…

A Brief Note On Comets

I’m just going to put some information and you pick what you want to put on the power point. Comets: Comets are celestial objects consisting of a nucleus made up of ice and dust, a head, and when near the sun, a tail of gas and dust streaming outwards. There are two types of comets, short-period and long-period comets. Short-period comets reside in an icy region called the Kuiper Belt and orbit the sun in less than 200 years. On the other hand, long-period comets are found from 5 thousand to 100…

Ecosystems at Risk - The Great Barrier Reef By Rhiannon Stewart-White Introduction: Every ecosystems functioning is dependent on the Earths four complex overlapping spheres, (the atmosphere, lithosphere, hydrosphere and the biosphere.) These linkages enable ecosystems to work in a state of dynamic equilibrium. An ecosystem is the intense link of biotic and abiotic environments. A major ecosystem and tourist attraction in Australia is The Great Barrier Reef, which roughly covers an amazing 2300…

Chemistry: Atoms, The Basis Of Chemistry

neutrons are neutral. Compounds are formed when two or more different elements react chemically together, e.g. H2, O2, N2, Cl2, nitrogen oxide, water, nitrogen dioxide and carbon dioxide An element is a pure substance of one type of atom, e.g. zinc, oxygen, aluminium and copper. A mixture is a combination or elements or compounds, in which you can separate them again e.g. sand + water, salt + water, and sugar + salt. An alloy is a metal made by combining two or more metallic elements, e.g. bronze…

the biosphere, lithosphere, hydrosphere and atmosphere contain examples of mixtures of elements and compounds. Biosphere: consists of living things which are made up of cells. Cells contain large amounts of water, thus, oxygen and hydrogen are abundant, and contain complex carbon compounds such as proteins and fats. Lithosphere: consists of numerous minerals that are combined in different proportions to form sedimentary, igneous and metamorphic rocks. Hydrosphere: water is the most abundant compound;…
