Slate: _______________
Limestome: _______________
What are igneous, metamorphic, and sedimentary?
In a process of forming igneous rock, __________ into magma is caused by an increase in temperature in rock deep below the Earth's surface.
What is melting?
In the process of forming metamorphic rocks, temperatures caused by intense _________ can change a rock's structure but not melt it.
What is heat?
The model that describes the formation, breakdown, and reformation of a rock is known as the ___________________.
What is the rock cycle?
It is true or false that sedimentary rocks sometimes contain fossils.
What is true?
Sandstone is __________________. Granite is ______________, while gneiss is ______________.
What are sedimentary, igneous, metamorphic?
These rocks have layered or banded appearance or crystals.
What are metamorphic rocks?
When sedimentary rocks are formed, the sediments go through ___________________, meaning they are buried and placed under intense pressure from underlying rocks.
What is compaction?
This type of rock is formed when sediments accumulate and compact and cement together.
What is a sedimentary rock?
_______________ is the geologist who developed the concepts of the rock cycle.
Who was James Hutton?
Conglomerate: ____________________
Basalt: ___________________
Marble: ___________________
What are sedimentary, igneous, metamorphic?
Sediments are moved around by wind, water, gravity, and ice, leading to deposition. This process is known as _______________.
What is erosion?
In another process that forms sedimentary rock, new minerals stick together like glue, tightly holding grains together.
What is cementation?
This type of rock is formed by heat and pressure buried deep below Earth's surface.
What is a metamorphic rock?
This type of rock is often deposited in layers.
What is a sedimentary rock?
Quartzite: _____________________
Pumice: ___________________
Flint: ____________________
What are metamorphic, igneous, and sedimentary?
In the process of forming igneous rocks, melted rocks turn _____________ by cooling and hardening.
What is solid?
Chemical changes, rain, ice, wind, and living things create loose materials called sediments, a process known as _____________.
What is weathering?
This type of igneous material cools faster due to its location in or on the Earth's crust: magma or lava.
What is lava?
What is melting?
Tuff : ___________________
Schist: __________________
Breccia: _________________-
What are igneous, metamorphic, and sedimentary?
Picturing the rock cycle diagram, these two processes are what igneous, sedimentary, or older metamorphic rock undergo to turn into metamorphic rock.
What are heat and pressure?
Movement of the Earth's tectonic plates creates intense ____________ and _____________ below the Earth's surface.
What is heat and pressure?
Picturing the rock cycle diagram, these two processes are what igneous, metamorphic, or older sedimentary rocks undergo to turn into SEDIMENTS before new sedimentary rock.
What are weathering and erosion?
This is the type of earth scientist/geologist whose studies focus on rocks.
What is petrologist?
