Q

how are fine and course grained textures formed

A

forms from magma or lava cooling quickly/ course is from it cooling slowly

16
Q

what are biochemical sedimentary rocks

A

they form from the body of onnce living things

17
Q

how do coral reefs form

A

from little dead animals

18
Q

what is the difference between contact and regional metamorphism

A

contact metamorphism is when magma forces its way into the rock. regional metamorphism is when tectonic plates collide and form mountains. covers a wide area

19
Q

what are the three agents of metamorphism

A

heat fluid pressure

20
Q

what are foliated rocks

A

when they are flattened and line up on parallel bands

21
Q

what are nonfoliated rocks

A

rocks with no bands

22
Q

slate parent

A

shale

23
Q

gneiss parent

A

granite

24
Q

quartzite parent

A

sandstone

25
Q

what are the two types of pressure, where are they directed at

A

confinning and directed. confining pressure points equally in all directions, directed is toward one spot

26
Q

what is the rock cycle order

A

cooling and crystallization from magma=igneous rock erosion and deposition=sediment cementation and compaction=sedimentary rock heat and pressure=metamorphic rock melting to magma

27
Q

where do sea anemones live

A

in the holes of coral

28
Q

what minerals make rocks green

A

hornblen,serpentine

29
Q

what does metamorphic mean

A

meta=form mophic=change

30
Q

what are inttrusive rocks

A

cool slowly underground with bog crystals

31
Q

what are extrusive rocks

A

when lava cools on earths surface. cools quickly which causes no or not very many minerals.

32
Q

what are the three main components of texture

A

coarse grained, glassy texture, and porphyrite texture
