Ryholite
volcanic rock
rich in quartz
formed when viscous lava is blocked, builds up and explodes
pyroclastics
superheated gas and rock up to 1000 ºC moving upward at speeds up to 700 k/hr.

consist of crystals of different minerals

banded
ignimbrite
results from eruption of fluid lava and gas in a dense glowing cloud

behave like plastics and form bands
Non-selective deposit feeders
ingest bulk sediment materials and digest the organic detritus and associated microbes
Selective deposit feeders
sort much of the sediment prior to ingestion
Salt marsh stresses
•Wetland plant pore spaces are filled with water so the roots cannot get oxygen in the same way as normal land plants

•Sulfides and iron compounds get reduced into toxic compounds in wetland conditions

•Salt-sodium in plant cells denaturalizes emzymes

•temp and irradiation
C4 Plants
•uses carbon more effectively than a C3 but has to fix carbon twice so has to use more energy

•has lower transpiration rate b/c can use up to 80% full sunlight so they can photosynthesize all day long vs. 50% for C3 which have to shut down at some point in the day

•agranular chloroplasts wrapped around the veins of a plant, veins carry heat away cooling the plant. C3 have stacked chloroplasts with electrons bouncing around creating heat
CAM Plants
• Stomata only open at night and store CO2 in vacuoles, during day stomata close and plant uses CO2
