Waters in the coastal ocean tend to be more productive than waters of similar depth in the open ocean. What is the main reason f
Jet001 [13]

Answer:

The coastal ocean seems to be more productive than the waters of the similar height in the open ocean due to ample availability of water, sunlight, and nutrients. The coastal ocean has more nutrients due to the process of upwelling, that is, movement of water offshore by the currents.

Also, water situated on the continental shelves is comparatively shallower and thus it is turbulent. This mixing or turbulence keeps settling the nutrients stirred up and accessible, and eventually, ample of nutrients erode off the continents themselves and so water nearby to the shore seems to be greater in nutrients.  

On the other hand, in the surface water away from the coastlines, usually, there is a lot of sunlight but no availability of adequate nutrients. Therefore, the majority of the ocean surface is not much productive.

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a:________
sweet [91]

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a Tuff.

  • A form of rock called tuff is created when volcanic ash is blasted from a vent during an eruption.
  • The ash is transformed into a rock after ejection and deposition. Tuff is defined as rock with an ash content of more than 75%, whereas tuffaceous refers to rock with an ash content of 25% to 75%.
  • The thickness of tuff often decreases with distance from the volcano and is usually greatest close to the volcanic vent. The typical shape of a tuff deposit is that of a "lens," not a "layer."
  • Tuff may also be thickest on the vent's side that faces away from the wind or on the side facing the direction of the blast.
