Unit 5 Hydrosphere (part 2) 

________ are on the ocean floor and some are iron, cobalt, etc.

________: Is a measure of the amount of dissolved salt in the ocean.

________: a fissure in a planets surface from which geothermally heated water issues.

________ is the process by which certain microbes create energy derived from chemical reactions.

________ are known as Carbon Sinks and remove CO2 from the atmosphere.

________ helped impose many challenges like pressure.

Open Ocean: the sunlit top layer of the ocean beyond the continental shelves; the vast bulk of the sea, it covers over 360, 00, 00 square kilometers of the ________ and is referred to as the marine desert because nutrients are lower here than in the shallow seas; life can be scarce.

It is the region of the open sea beyond the edge of the ________ where the water measures 200 meters deep, or deeper.

________ is the main solute.

________ in the Ocean: ________ like O2, N2, and CO2 are very important in water just in the air.

________: The deepest part of the worlds ocean.

________- The intertidal zone becomes submerged in water.

________ used ropes and lead weights.

________: relatively shallow part of the ocean above the drop- off of the continental shelf, approximately 200 meters in depth.

________ and geysers on land and hydrothermal vents form in volcanically active areas often on mid- ocean ridges where the tectonic plates are spreading apart.

________: Most of life on Earth depends on photosynthesis, however, at hydrothermal vents the ecosystem has evolved in the absence of sunlight, and its source of energy is completely different: Chemosynthesis.

________: the portion of a lake or ocean where there is little or no sunlight; formally defined as the depths beyond which less than 1 % of sunlight penetrates.

________: the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub- surface layers.

________: Ocean water is a solution.

Downwelling is important because it brings oxygen down into the ________.

________ use up CO2 and release O2.

________: Deep sea divers were the first method of exploring the ocean.

________ do not boil because of extreme pressure.

________ is by the poles because it is cold.

________: the area of the shore and seabed that it exposed to the air at low tide and submerged at high tide.

________- The intertidal zone becomes dry from low water levels.

________: Areas of the sea floor where hot water heated by magma rushes out.

________: Satellites, sonar, and divers only scratched the surface of the ocean.

The ________ has NO oxygen production because there are no plants /no sunlight.

The ________ is the relatively shallow part of the ocean between the low tide mark and the continental shelf.

________ alone helped explore the abyssal depths.

The ________ receives plenty of sunlight with a relatively stable temperature, making it suitable for aquatic plants.

Deep sea divers were the first method of exploring the ocean

Satellites, sonar, and divers only scratched the surface of the ocean

submarines, ROV (remotely operated vehicles), Underwater Habitats

Beneath the worlds oceans lie ragged mountains, active volcanoes, vast plateaus, and almost bottomless trenches

The deepest part of the worlds ocean

Areas of the sea floor where hot water heated by magma rushes out

the portion of a lake or ocean where there is little or no sunlight; formally defined as the depths beyond which less than 1% of sunlight penetrates

the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers

the downward movement of fluid, especially in the sea, the atmosphere, or deep in the earth

Is a measure of the amount of dissolved salt in the ocean

Ocean water is a solution

Salt water is dense than fresh water

Gasses like O2, N2, and CO2 are very important in water just in the air

Fish and other food sources for eating
