Question 3

occurs when a dinosaur might have walked through mud and left tracks

Answer 3

trace

Question 4

once living material is replaced by minerals turning into stone

Answer 4

petrified

Question 5

which group of rock is most likely to have fossils

Answer 5

sedimentary because metamorphic and igneous undergo severe pressure

Question 6

transform boundaries

Answer 6

two plates sliding past each other in different directions

Question 7

divergent boundaries

Answer 7

two plates moving away from each other

Question 8

convergent boundaries

Answer 8

two plates moving towards each other

Question 9

subduction zone

Answer 9

usually on convergent boundaries, when a plate of oceanic crust collides with basaltic crust

Question 10

metamorphic to igneous

Answer 10

metamorphic rocks melt into magma. magma erupts and cools to create igneous rocks.

Question 11

igneous to sedimentary

Answer 11

igneous rocks undergo weathering and erosion until they turn into sediment. the sediment is compacted and condensed into sedimentary rocks.

Question 12

sedimentary to metamorphic

Answer 12

sedimentary rocks undergo heat and pressure until they form metamorphic rocks.

Question 13

igneous to metamorphic

Answer 13

heat and pressure

Question 14

metamorphic to sediment

Answer 14

weathering and erosion

Question 15

example of the rock cycle rocks

Answer 15

granite, sandstone, quartzite

Question 16

metamorphic

Answer 16

forms by: heat and pressure

characteristics: rough, heavy, hard, sparkly, potting/lines
examples: slate, marble, quartzite, schist, gneiss

Question 17

sedimentary rocks

Answer 17

forms by: erosion and then being compacted

characteristics: softest, muddy coloring, large chunks combined
examples: shale, limestone, sandstone, coal

Question 18

examples of igneous rocks

Answer 18

forms by: cool lava or magma

characteristics: black and grey, rough, mainly spotted, some spongy
examples: granite, balsalt, pumice, obsidian

Question 19

adaptation

Answer 19

a change or process of becoming better suited for your environment

Question 20

evolution

Answer 20

the process in which animals develop

Question 21

natural selection

Answer 21

the process in which organism adapt to become better suited for their environment. weaker organisms are eliminated

Question 22

fossil

Answer 22

remains or impressions of an organism

Question 23

Answer 23

crust, mantle, outer core, inner core

Question 24

what is the continental drift theory

Answer 24

alfred wegeners theory that the continents and the land masses were once in a super continent pangea and slowly drifted apart

liquid - iron and nickel

Question 35

which of earths layers is the thickest

Answer 35

mantle

Question 36

where is the lithosphere

Answer 36

upper mantle - solid divided into tectonic plates

Question 37

what is the asthenosphere

Answer 37

lower level of the mantle below lithosphere, liquid - mechanically weak

Question 38

why is the inner core solid

Answer 38

there is so much pressure, iron

convergent

Question 46

which boundary has earths crust neither created nor destroyed

Answer 46

transform

Question 47

which boundary is caused by convection currents

Answer 47

divergent boundary

Question 48

fossil type molds

Answer 48

an imprint that hardens without and actual organism form a hollow area in shape of an organism that was buried

Question 49

fossil type casts

Answer 49

a calcium carbonate of silica shell over the fossil that duplicates its shape. organism sinks into water and is covered by sediment

Question 50

fossil type trace

Answer 50

footprint or track

Question 51

fossil type carbon film/print

Answer 51

leaves or insects buried in mud and is covered in carbon. sediment buries organism and organism dissolves releasing gasses leaving behind thin carbon film
