earth science

Question 1

what is a rock made of

Answer 1

mixtures of minerals

Question 2

how does igneous rock from

Answer 2

magma cooling

Question 3

what is marbles parent

Answer 3

limestone

Question 4

what is a metamorphoic rock

Answer 4

when sedimentary rock compact together/heat and pressure

Question 5

waht are sedimentary rocks

Answer 5

sediments that are pushed together

Question 6

can igneous rock form above the surface

Answer 6

yes

Question 7

how do igneous rocks turn into sedimentary

Answer 7

erosion and depostion

Question 8

how are fine and course grained textures formed

Answer 8

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

Question 9

what are the three compositons of igneous rocks

Answer 9

granitic,basaltic,andesitic

Question 10

what is deposition

Answer 10

depostion is the settling of sediments in layers after it was moved during erosion

Question 11

what is wheatering

Answer 11

the process of rocks when they break into smaller pievces

Question 12

what is erosion

Answer 12

rocks broken down by wind or water and carried somewhere

Question 13

what is cementation

Answer 13

when water soaks through soil or rock

Question 14

what is a clastic sedimentary rock

Answer 14

made from broken pieces of other rocks and it compacted and cemented together

Question 15

what are chemichal rocks

Answer 15

chemical rocks form from water precipitation or evaporation

Question 16

what are biochemical sedimentary rocks

Answer 16

they form from the body of onnce living things

Question 17

how do coral reefs form

Answer 17

from little dead animals

Question 18

what is the difference between contact and regional metamorphism

Answer 18

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

Question 19

what are the three agents of metamorphism

Answer 19

heat fluid pressure

Question 20

what are foliated rocks

Answer 20

when they are flattened and line up on parallel bands

Question 21

what are nonfoliated rocks

Answer 21

rocks with no bands

Question 22

slate parent

Answer 22

shale

Question 23

gneiss parent

Answer 23

granite

Question 24

quartzite parent

Answer 24

sandstone

Question 25

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

Answer 25

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

Question 26

what is the rock cycle order

Answer 26

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

Question 27

where do sea anemones live

Answer 27

in the holes of coral

Question 28

what minerals make rocks green

Answer 28

hornblen,serpentine

Question 29

what does metamorphic mean

Answer 29

meta=form mophic=change

Question 30

what are inttrusive rocks

Answer 30

cool slowly underground with bog crystals

Question 31

what are extrusive rocks

Answer 31

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

Question 32

what are the three main components of texture

Answer 32

coarse grained, glassy texture, and porphyrite texture
