This planet is 19 AUs aways from the sun, it was the 1st planet discovered by a telescope in 1781, and is tilted 90* on it's axis.

Giant, far from sun, made of gases & liquid metals at core.

The rapid change in temperature in the transition zone

This life zone is made up of the deep ocean floor, mostly the aphotic zone, has extremely cold temperatures, extremely high pressures, and a food source of dead plankton and bodies of larger organisms that sink to the bottom.

This makes up of about 30% of the Earth's surface, and includes: the abyssal plain, seamounts, deep sea trenches at convergent plate boundaries, and deep sea basaltic plateaus

This planet has twice the mass of all other planets combined, has more than 20 moons, releases more energy than it receives, has the strongest magnetic field in the solar system, and has a "Giant Red Spot"

These objects are rocky and metallic, are about 100 m in diameter, and are 95% stony, and 5% metal (typically iron)

1) Continental Weathering
2) Outgassing at mid-ocean ridges

These are microscopic plant, animal, and bacteria floaters.

A current due to friction between the ocean's surface and the wind that blow across it, it is very localized

Every 20 years, this planet is the last planet instead of Pluto. Has CH4 and NH3 atmosphere

This planet is a little smaller than Jupiter, has rings made mostly of frozen gases, and some rocky debris, is twice as far from the sun than Jupiter, and it's moon Titan, has it's own atmosphere

This refers to the total amount of dissolved material in volume sea water, and is expressed in terms of per mil.

The area between high and low tides. Has difficult living conditions due to: constant change in water depth, rapidly changing temperature and salinity, crashing waves, alternating between wet and dry, and rapidly changing O2 levels.

live ON the seafloor Ex: starfish, barnicles, oysters, clams, crestacians

small, made of silicates & metals, have thin atmospheres

This planet is has a similar size and mass to Earth, has an extremely thick, cloudy atmosphere, and has evidence of past volcanism

1) Marine organisms making hard parts
2) Chemical precipitation as sediments

live IN the seafloor Ex: worms

This area has lots of sunlight, but always a strong thermocline preventing the mixing of deep nutrient-rich water with sunlit surface waters, and has a low productivity.

This planet is the closest plant to the sun, has no atmosphere, and has a very dense, large iron core.

These objects are also known as "dirty snowballs", they come from the Kuiper Belt, have very long and highly elliptical orbits, and is the reason for Earth's meteor showers

This division of the sea floor has both active and passive sub-divisions.

These are all of the marine organisms that can move independent of ocean currents. (Can swim or use other propulsion) Ex: fish, squid, marine mammals, and marine reptiles.

This current is due to: global pattern of prevailing winds, position of continents, and the caiolis force (Earth's rotation)
