What is the limiting factor in determining the accumulation of siliceous ooze/calcareous ooze, respectively?
zhannawk [14.2K]

Answer:

productivity and water depth

Explanation:

The productivity and the depth of water are both equally important as it directly affects the accumulation of biogenic sediments such as the siliceous ooze and calcareous ooze. In the equator and the coastal upwelling areas, and at the site of divergence of oceans, there occurs a high rate and amount of productivity, and these are considered to be the primary productivity.  

The siliceous oozes are a good indicator of extensively high productivity in comparison to the carbonate oozes. The main reason behind this is that the silica can be easily dissolved in the surface water. On the other hand, the carbonates dissolve at a relatively lower ocean water depth, so there requires a high amount of surface productivity in order to allow these siliceous oozes to reach the ocean bottom.

Thus, the water depth and productivity, both are considered as the limiting factor in determining the accumulation of biogenic oozes.

(1) In an experiment for determining the density of water, the following results
Angelina_Jolie [31]

Given parameters:

mass of an empty beaker = 65gm

mass of the beaker and water = 165gm

volume of water = 100cm³

Unknown:

Density of water  = ?

Solution:

Density is the mass per unit volume of a substance;

           Density  = \frac{mass}{volume}

To find the mass of the water ;

   Mass of water  = Mass of beaker and water - mass of an empty beaker

                            = 165g - 65g

                           = 100g

So input parameters and solve;

         Density  =  \frac{100g}{100cm^{3} }  

         Density of the water in the beaker  = 1g/cm³
