What properties would you expect the water to have in the deep zone?

- Oceanographers are scientists who study the ocean and its inhabitants. They use a variety of tools, including: thermometers (temperature), hydrometers (salinity - or salt content), CTD (conductivity-temperature-depth), fathometers (ocean depth), and submersible submarines (the ocean bottom).
- The temperature and salinity of the water determine its density. Cooler water is denser than warmer water so it sinks to the bottom. Salty water is denser than less salty water.
- The different water densities divide the ocean into three zones: mixed zone, transition zone, and deep zone.
- The surface of the water is warmer than the bottom, because the sun's rays hit there directly. Also, water is warmer closer to the equator than farther north. Closer to the Poles, sunlight hits at an angle, so the warmth is spread over a wider area.
- Currents redistribute heat around the globe. Cold-water currents move from the Poles to the equator. Warm-water currents move from the equator to the Poles.
- Upwelling occurs when seasonal winds push water away from the coast and cooler, nutrient-rich water from the bottom rises to take its place.
- The different ocean zones are: epipelagic (sunlit), mesopelagic (twilight), bathypelagic, abyssopelagic, hedalpelagic (midnight zones).

Which type of rock would you expect to exist deep in the Earth's crust?
You would expect to find igneous or metamorphic rocks, depending on the depth.
Which feature would you expect to find at the mouth of a submarine canyon?
A deep sea fan
Why would you not expect to find a metamorphic rock in the recesses of the earth?
You WOULD expect to find metamorphic rocks in the recesses (deep layers) of the Earth's crust. But not in the mantle or core. Metamorphic means changed - and rocks - either sedimentary or igneous - get changed by the heat and pressures found in the deep crust.
Why crabs are found in low tide only?
because usually they are deep under the water but when the tide goes out they are where the deep water would have been.
Would you expect the seawater just below the floating ice in the Arctic Ocean to be higher or lower in salinity then the water in the deep zone there?
When ocean water freezes into sea ice, some of the salt is incorporated into the new ice. Thereafter, that salt drains as brine (salt plus water), causing the layer of water below to be of higher salinity.
What climate would you expect to find temperate forests?
"Mostly in-deep water mainly far out in the ocean".
Which type of rock would you expect to exist deep in the Earth's crust?
You would expect to find igneous or metamorphic rocks, depending on the depth.
Which feature would you expect to find at the mouth of a submarine canyon?
A deep sea fan
What type of rock would you expect to be most common on the floor of a large deep lake?
basalt
What factor would limit the growth of algae in deep ocean water?
The cold would affect it from growing in the deep water and depending on how deep the it would receive less and less sunlight which it needs to grow
Who sang the song smoke on the water?
That would be Deep Purple.
Is deep water more or less dense than shallow water?
Shallow water is more dense than Deep water. This means that a wave travelling from deep water to shallow water would bend towards the normal. Also, the wave would travel slower in the shallow than in the deep water
Why would you not expect to find a metamorphic rock in the recesses of the earth?
You WOULD expect to find metamorphic rocks in the recesses (deep layers) of the Earth's crust. But not in the mantle or core. Metamorphic means changed - and rocks - either sedimentary or igneous - get changed by the heat and pressures found in the deep crust.
What regions would you expect to find the largest amounts of dissolved oxygen in the ocean floor?
in the deep oceon floor
Would you expect to find many organisms living at the bottom of deep lake?
Yes, more than at the surfase.
In which of the regions would you expect to find the largest amounts of dissolved oxygen in the ocean water A near the equator B in temperate zones C in polar regions D in the deep ocean floor?
Polar Regions.
Why crabs are found in low tide only?
because usually they are deep under the water but when the tide goes out they are where the deep water would have been.
