Team Quest Geology Terms
a force that builds up mountains and landmasses on Earth's surface
a force that slowly wears away mountains and other features on the surface of Earth
vibrations that travel through Earth carrying the energy released during an earthquake
the force pushing on a surface or area
the thin and solid outermost composition layer of the Earth above the mantle
A dark, dense, igneous rock with a fine texture, found in oceanic crust
A usually light colored igneous rock that is found in continental crust
the composition layer of the earth between the crust and the core; it makes up 67% of Earth's mass.
the solid part of the earth's physical layers consisting of the crust and outer mantle
the soft physical layer of the mantle on which the lithosphere floats
The strong, lower part of the mantle between the asthenosphere and the outer core
a dense sphere of solid iron and nickel at the center of Earth
the liquid layer of the Earth's core that lies beneath the Mantle and surrounds the inner Core
the movement of energy from a warmer object to a cooler object
the transfer of heat energy through space
the direct transfer of heat from one substance to another substance that it is touching
the transfer of heat by the movement of a fluid (gas or liquid)
the amount of matter in a given space
circular movement of a substance due to changes in temperature and density; found in Earth's asthenosphere.
a type of rock that forms from the cooling of molten rock at or below the surface
A type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together
A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions
matter deposited by some natural process
condition in which the earth's surface is worn away by the action of water and wind
process in which sediment is laid down in new locations
The process by which sediments are pressed together under their own weight.
The process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock.
a series of processes on the surface and inside Earth that slowly changes rocks from one kind to another
the age of a rock compared to the ages of rock layers
the age of a rock given as the number of years since the rock formed
:Law of Superposition
The geologic principle that states that in horizontal layers of sedimentary rock, each layer is older than the layer above it and younger than the layer below it.
An igneous rock layer formed when magma hardens beneath Earth's surface.
an igneous rock layer formed when lava flows onto Earth's surface and hardens
fossils of widely distributed organisms that lived during only one short period
a break in the geologic record created when rock layers are eroded or when sediment is not deposited for a long period of time
