SSA Review - Earth

Earth Science SSA Review

QuestionAnswer
Weathering Breaking down rock into smaller pieces of sediment
Erosion The movement of sediment from one place to another
Depostion Sediment settles in a new location
Geosphere The rocky part of the earth... land, soil, rocks, continents
Hydrosphere All water on earth
Cryosphere Frozen water on earth... ice caps, glaciers
Biosphere The living systems of earth
Atmosphere The layer of air that surrounds the planet
Thermosphere The outermost layer of the atmosphere, very hot
Mesosphere The layer of the atmosphere that protects the earth from meteors
Stratosphere The layer of the atmosphere that contains the ozone layer, and absorbs UV radiation
Troposphere The lowest layer of the atmosphere, that contains weather and clouds
UV Radiation Dangerous rays from the sun that cause skin cancer. We are protected from these by the Ozone layer
Climate Change Change in the average temperature of the planet due to increased amounts of carbon dioxide in the atmosphere
Weather The current conditions in a particular area
Climate The long-term pattern of a region
Radiation Heat that travels through space. Ex: heat from the sun
Conduction Heat that travels through contact. Ex: Warm ocean water heats the air through contact
Convection Warm air and/or liquid heats and rises up... then cools and sinks, creating a cycle
Igneous Rock Made from cooled magma/lava
Metamorphic Rock Made from other types of rock, changed by heat and pressure inside the earth
Sedimentary Rock Rock made from built up sediments
Crust Surface layer of the earth, contains the tectonic plates
Mantle Melted rock (magma) moves in convection currents underneath the crust
Outer Core Liquid, center of the earth
Inner Core Solid, center of the earth
Theory of Plate Tectonics The crust is made of tectonic plates that move
Continental Drift Theory Continents were once connected in a super-continent, Pangaea. Over millions of years they separated and moved to their current locations
Convergent Boundary Plates that push together
Divergent Boundary Plates that pull apart
Transform Boundary Plates that move parallel to each other
Law of Superposition Newer rocks are on top... older rocks are deeper.
Relative Dating Uses law of superposition to determine approximate age of rocks compared to others around them.
Absolute Dating Uses radioactive dating (carbon dating) to determine the more exact age of a rock/fossil by measuring radioactive decay of atoms.
