Nataliya [291]
Starch is a high molecular weight substance; therefore, it is insoluble to our cells. It needs to be broken down to simple sugars like glucose in order for it to be dissolved/absorbed in our blood. This is because simple sugars has smaller molecular weights and are more soluble.

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.
