Ignorant Igneous
This is molten rock found below the earth's surface.
magma
tiny pieces of rock, sand, shells, etc. is called what
sediment
metamorphic rocks can be made from ____________, _______________, or _______________________ rocks.
sedimentary, metamorphic or igneous.
When sediments go under compacting and cementing processes they become___________
Sedimentary rocks.
A fracture or zone of fractures between two blocks of rock.
a fault
Name a type of mineral found in rock
lots of examples.
This is molten rock found above the earth's surface.
lava
The final 2 processes that turn sediments into sedimentary rocks.
compaction and cementation
Why are the layers of a metamorphic rock wavy, while sedimentary rock has straight, flat layers?
Metamorphic rocks have wavy, not straight layers due to heat and pressure
When igneous, metamorphic and sedimentary rocks go under weathering and eroding they become_________________
sediments
Trilobite or Dinosaur, which one lived on earth first?
trilobite
Define The rock cycle
shows us how different rocks change types.
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
extrusive and intrusive.
What is the difference between weathering, erosion and deposition?
Weathering breaks rock down, erosion carries it away and deposition drops the sediment off.
Above or below the Earth's surface, where do metamorphic rock form?
below the Earth's surface
The processes that turn metamorphic rocks into sediments
Weathering and erosion
what are Fossils
the remains or impression of a prehistoric plant or animal embedded in rock
The oldest rocks on earth are found in which layers
The bottom layers
__________ igneous rocks have larger crystals than the other kind of igneous rocks.
intrusive
This type of sedimentary rocks form when dead plants from millions of years ago mineralizes. We use it to heat homes
coal or organic sedimentary rock
what are parent rocks.
the original rock before it is changed by heat/pressure to become metamorphic.
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
Heat and pressure
youngest rocks are found on which layer?
Top
The study of rocks, their history and the processes that form and change them.
geology
An example of this type of igneous rock is the Stone Mountain in Georgia. This happens when magma cools above the Earth's surface.
extrusion igneous rock
When rocks crack due to the expansion of water
freeze/thaw weathering
Shale is the parent rock of this metamorphic rock.
slate
When metamorphic and igneous rocks go under melting they turn into__________
Magma
the “calendar” for events in Earth history, used to determine how old a fossil is.
geologic time scale
process where gas turns into liquid
condensation
