Term
Earth Science[image]
Definition
is the study of the Earth and its neighbors in space. It is an exciting science with many interesting and practical applications. Some Earth scientists use their knowledge of the Earth to locate and develop energy and mineral resources.
Term
astronomy[image]
Definition
the branch of science which deals with celestial objects, space, and the physical universe as a whole.
Term
Meteorology is:[image]
Definition
the branch of science concerned with the processes and phenomena of the atmosphere, especially as a means of forecasting the weather.
Term
geology[image]
Definition
the science that deals with the earth's physical structure and substance, its history, and the processes that act on it.
Term
Geosphere[image]
Definition
The mostly solid, rocky part of the Earth; extends from the center of the core to the surface of the crust.
Term
atmosphere[image]
Definition
the envelope of gases surrounding the earth or another planet.
Term
Hydrosphere[image]
Definition
all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.
Term
tectonic plate[image]
Definition
a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
Term
Pangaea [image]
Definition
The name of the single landmass that broke apart 200 million years ago and gave rise to today's continents
Term
Erosion[image]
Definition
the process of eroding or being eroded by wind, water, or other natural agents.
Term
earthquake[image]
Definition
Shaking and vibration at the surface of the earth resulting from underground movement along a fault plane of from volcanic activity
Term
Volcanoes[image]
Definition
openings in Earth's crust from which molten rock, dust, ash, and hot gases flow or erupt
Term
Weathering [image]
Definition
The chemical and physical processes that break down rock at Earth's surface.
Term
chemical weathering[image]
Definition
the process by which rocks break down as a result of chemical reactions
Term
mechanical weathering [image]
Definition
The type of weathering in which rock is physically broken into smaller pieces
Term
divergent boundary [image]
Definition
The boundary between two tectonic plates that are moving away from each other
Term
convergent boundary [image]
Definition
A tectonic plate boundary where two plates collide, come together, or crash into each other.
Term
Subduction[image]
Definition
the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
Term
transform boundary [image]
Definition
The boundary between tectonic plates that are sliding past each other horizontally
Term
Convection currents[image]
Definition
Circular currents in the mantle caused by the magma being heated by the core off the Earth.
Term
ridge push[image]
Definition
a mechanism that may contribute to plate motion; it involves the oceanic lithosphere sliding down the oceanic ridge under the pull of gravity
Term
Convection [image]
Definition
The transfer of thermal energy by the circulation or movement of a liquid or gas
Term
Conduction[image]
Definition
Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.
Term
Radiation [image]
Definition
Energy that is radiated or transmitted in the form of rays or waves or particles.
Term
slump[image]
Definition
the downward slipping of a mass of rock or unconsolidated material moving as a unit along a curved surface
Term
avalanche[image]
Definition
A great mass of ice, earth, or snow mixed with rocks sliding down a mountain
Term
Shearing[image]
Definition
stress that pushes a mass of rock in two opposite directions
Term
Foliation [image]
Definition
The metamorphic rock texture in which mineral grains are arranged in planes or bands.
Term
Lava[image]
Definition
Liquid magma that reaches the surface; also the rock formed when liquid lava hardens.
Term
Magma[image]
Definition
A molten mixture of rock-forming substances, gases, and water from the mantle
Term
compaction[image]
Definition
the process that presses sediments together
Term
Texture[image]
Definition
The feel, appearance, or consistency of a surface, substance, or fabric.
Term
rock cycle[image]
Definition
an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion.
Term
extrusive rock[image]
Definition
igneous rock formed from lava that erupted onto Earth's surface
Term
Intrusive rock bodies [image]
Definition
bodies or structures that penetrate or cut through pre-existing country rock
Term
Deposition[image]
Definition
Process in which sediment is laid down in new locations.
Term
Crystallization[image]
Definition
The process by which atoms are arranged to form a material with a crystal structure
Term
Sedimentary [image]
Definition
(of rock) that has formed from sediment deposited by water or air.
Term
Metamorphic [image]
Definition
A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.
Term
Igneous [image]
Definition
a type of rock that forms from the cooling of molten rock at or below the surface
