Earth science yr 10
| Question | Answer |
|---|---|
| Biosphere | The zone that encompasses all living organisms on the planet. |
| Lithosphere | The upper layer of mantle and the crust and includes all geological features on the surface of the planet. |
| Hydrosphere | Includes all the water present on the planet in solid, liquid and gaseous states. |
| Atmosphere | The layers of gas that surround the planet. |
| Natural Greenhouse effect | the natural process that maintains the temperature of the Earth and explain how it helps to maintain earth’s surface temperatures. |
| carbon reservoir/sink | a feature of the environment that absorbs more carbon than it releases. e.g. examples such as limestone, forests, oceans and fossil fuels. |
| major greenhouse gases | CO2, H2O, methane, nitrous oxides. |
| how ocean currents distribute heat around the earth. | thermohaline circulation for deep currents gyres for surface currents |
| thermohaline circulation | |
| gyres | loops created by ocean currents |
| main processes of the carbon cycle | photosynthesis, respiration, combustion, fossilisation. |
| combustion | |
| fossilisation | |
| enhanced greenhouse effect. | |
| anthropogenic | ‘originating in human activities’ which produce or result in the creation of anthropogenic GHGs such as coal, oil and gas. |
| Different Parts of Atmosphere | Troposphere, Stratosphere, Mesosphere, Thermosphere (in order) |
| Troposphere | 1st layer of atmosphere |
| Stratosphere | 2nd layer in atmosphere; ozone layer located in. |
| Mesosphere | 3rd layer, makes up ionosphere |
| Thermosphere | 4th layer, makes up ionosphere |
| Ozone | |
| Ways carbon returned to atmosphere | |
| Geosequestration | |
| Carbonification | |
| Carbon sequestration | |
| Salinty | |
| Perihelion | some time of the year the earth will be closer to the sun |
| Aphelion | times, the sun will be farther from the earth |
| The amount of energy absorbed by earth is affected by | Earths orbit, spherical shape of earth, Tilt of Earth's axis, Albedo effect, oceanic currents (temp), Surface oceanic currents, f |
| Earths orbit | sometimes the sun is closer and sometimes further apart, varying earths radiation at the top of the atmosphere. |
| spherical shape of earth | the perihelion has incident light rays perpendicular to the ground. By moving towards the poles, the earth surface tilts in regards to incoming rays, with regions furthest away aligned in parallel with the radiation, thus receiving no energy. |
| Tilt of Earth’s axis | earth tilts 23.5 degrees with respect to its plane of orbit. During solstices, incoming radiation is perpendicular to earth surface on either the latitude of Cancer or the latitude of Capricorn |
| Albedo effect | reflective power of a surface (e.g. white is 1 black is 0) Earth's icecaps are naturally white in colour therefor reflecting 90% of sunlight, |
| Oceanic currents- due to temperature | As water cools down it becomes denser and sinks to the bottoma dntravels to the tropics where it moves up towards the surface and the cucle starts again regulating earths tempurature. |
| Surface Oceanic currents | Surface ocean currents move in predictable ways for thousands of kilometres and are not affected by changes in weather because they depend on factors that do not change. |
| Global wind pattern | global winds blow in the same direction all the time due to unequal heating of Earth surface. More radiation strikes the equator than the polar regions. the rotation of the earth makes winds predictable which push surface currents in their direction |
| Coriolis effect | makes objects appear to curve when moving in a straight line due to earth’s rotation. northern hemisphere the= clockwise direction southern hemisphere = anticlockwise motion |
| Shape of oceans basins | |
| Causes of temp rise | increase in concentration of greehouse gases (CO2, water vapour, methane, nitrous oxide) |
| Consequence of global warming | climate change, change in weather patterns, rising sea levels, spread of invasive species, melting polar icecaps and glaciers, spread of tropical diseases, increase in temp of upper levels of oceans. |
| ocean acidification |
