A stream carves a channel through soil rock by removing a few small particles of rock at a time. The stream water slows down when it enters a pond, allowing the rock particles to settle at the bottom of the pond. Pressure combines these particles into a solid rock. What is the new rock
called?
quartz rock
igneous rock
sedimentary rock
metamorphic rock

The answer is Sedimentary rock.

Explanation:

The stream water slows down when it enters a pond, allowing the rock particles to settle at the bottom of the pond. Pressure combines these particles into a solid rock.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
