Yes
the depth does affect the temperature because less sun light gets to the bottom to get less heat
light, light decreases with depth, affecting photosynthesis The deeper in the ocean you go, the less sunlight is present, and the less vigorous are algae. At some particular depth, the algae can no longer support themselves, so they cannot live at the depth (or deeper).
almost no silica in ocean water but most of its the earths crust.
The depth of water at the apex of the ridge is less than 2,700 metres.
False. The deepest ocean in the world is the PacificOcean with an average depth of 13,740 feet ( 4,188 meters). The Atlantic Ocean only comes in at third place (after the Indian ocean) at a 700 meters (2,300 ft) less average depth .
no water covers 71% of the earths surface and land 29%
As wer gets deeper there is less oxygen and it gets colder.
Sunlight can penetrate into the ocean to an average depth of about 200 meters (656 feet). This depth can vary depending on factors such as water clarity, time of day, and geographic location. Beyond this depth, the ocean becomes progressively darker as less sunlight is able to penetrate.
As wer gets deeper there is less oxygen and it gets colder.
as altitude rises less there is less atmospheric pressure
Because of less gravity in high altitude
By average wave size, the Arctic Ocean, since for most of the year it is covered by pack ice, and the average depth is less around the continents.
