EScAPES Unit 4

Bathymetric

topographic map of the Ocean Floor

Biogeography

how organisms are ecologically dispersed over different areas

BioMass

the total quantity or weight of organisms in a given area or volume

Biome

an area classified according to the species that live in that location

Conduction

energy transfer through solids via vibration of atoms

Convection

energy transfer in fluids in a circular nature via density differences

Endemic Species

a species that is native and isolated to a small geographic area

Erosion

transport of sediment and earth materials via wind, water, or gravity

Extrusive

igneous rock type formed from lava from outside the volcano

Felsic

rich is Si, Al, light in color, low in density

Habitat

place where an organism makes its home

Hot Spot

volcanic location,thought to be fed by underlying mantle, that is comparatively hotter than the surrounding mantle and crust

Joule

unit of energy in the SI system

Keystone Species

a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically

Kilowatt Hour

non-SI unit of energy equal to 3.6 megajoules in SI units which is the energy delivered by one kilowatt of power for one hour

Mafic

rich in Fe, Mg, dark in color, high in density

Magma

molten rock inside of Earth that is mineral rich and contains water

Mid-Ocean-Ridge

series of volcanoes that mark a divergent boundary

Peat Bog

wet spongy ground of decomposing vegetation

Resource Partitioning

process where different species divide limited resources to reduce competition, allowing them to coexist in the same habitat

Sulfur Dioxide

SO2, is a colorless gas produced from the burning of fossil fuels and the smelting of mineral ores that contain sulfur, and volcanic outgassing

Tundra

a vast, flat, treeless Arctic region of Europe, Asia, and North America in which the subsoil is permanently frozen

Volcanic Outgassing

gas escaping an active volcano containing H2O, N2, CO2 and Sulfur Dioxide
