big bang correct answers an explosion of matter origination from a concentrated point in space.
thought to have occurred 13.7 billion years ago
iron catastrophe correct answers occurred 4 billion years ago, earth began to melt, temperatures
reaching 1538 C. converted parts mass to liquid forcing denser elements to sink (iron and nickel)
and less dense elements (silicon, oxygen, carbon, magnesium) to rise towards the earths surface
benthic correct answers organisms that live on the bottom of the ocean (sea stars)
refers to any part of the ocean that touches the bottom and can be part of a beach or rocky
intertidal or can be part of the deeper provinces of the ocean
(intertidal, continental shelf, continental slope, abyssal, hadal)
pelagic correct answers organisms that live in the water column (fish)
decided into two horizontal sections (neritic, and oceanic)
refers to the portion of the ocean that does not touch bottom
(epipelagic, mesopelagic, bathypelagic, abyssal pelagic, hadalpelagic)
continental shelf correct answers shallowest part of the ocean and makes up less than 10% of the
surface area of the ocean. however it has a great nutrient supply and adequate light for most
photosynthetic organisms so it has some of the highest biological productivity within the ocean
neritic correct answers refers to the portion of the ocean near the coast between the shore and
where the continental shelf slopes down and becomes the continental slope (area above the
continental shelf)
shallowest zone
continental slope correct answers area where the bottom slopes distinctly downward
oceanic zone correct answers refers to the open ocean area beyond the continental shelf
epipelagic correct answers refers to the surface waters (down to 200m) where light and therefore
life is generally abundant
makes up only 3% of the total volume of the ocean yet it is the location of the majority of life in
the ocean
mesopelagic correct answers area below the epipelagic that has decreasing light
(200m - 1000m)
bathypelagic correct answers below epipelagic and has zero light
(1000m to 4000m)
abyssalpelagic correct answers below epipelagic and has zero light
(4000m - 6000m)
, hadalpelagic correct answers below epipelagic and has zero light
(6000 m to 11000m
equatorial correct answers *ocean biomes*
Areas near the equator that has high levels of moisture and low temperature seasonality.
Generally located in the zone bordered by 5° South and 5° North.
tropical correct answers *ocean biomes*
Locations north and south of the equator that has a summer rainy seasons and a winter dry
season. just beyond the equatorial zones and include 5° North and 23.5° North and 5° South and
23.5° South.
subtropical correct answers *ocean biomes*
Areas dryer than tropical locations (terrestrial equivalent of most deserts), bounded by the Tropic
of Cancer or the Tropic of Capricorn. Generally defined as the area between 23.5°; North and
40° North and 23.5° South and 40° South.
temperate correct answers *ocean biomes*
Zone between the subtropical and polar zones that have high seasonality with four distinct
seasons and a mild climate. generally located between 40° North and 60° North and between 40°
South and 60° South.
polar correct answers *ocean biomes*
Areas near the North and South Poles with short summers and long and cold winters. The region
is generally defined as north of 60° north latitude (Arctic Circle) or south of 60° south latitude.
sea water correct answers much denser than air and pure water. higher heat capacity than air so
better insulator, temperature changes are less dramatic in this than on land
less dense as a solid (ice), than as a liquid --> explains why icebergs float
one of the highest latent heat of melting and evaporation of any natural substance (makes for a
stable environment for life)
UNLIKE freshwater, this water density increases as the temperature decreases from 4 to -2
degrees C. (freezing point of average salinity)
element correct answers any substance that is made up of only one kind of atom (gold, helium,
silicon)
molecule correct answers when two or more atom combine. (water is made up of 2 hydrogen
atoms bonded to one oxygen atom)
