B. metamorphic rock in which mineral grains are NOT arranged in
bands
Slide 4
C. rock that cools at the Earths surface
Slide 5
A. process in which layers in sedimentary rock are formed
Slide 6
D. layers found in sedimentary rocks
Slide 7
Sedimentary rock is formed through the process of
__cementation_____.
Slide 8
How did humans use rocks in the past? To make tools
Slide 9
What are the main categories of sedimentary rock? Clastic,
chemical, organic
Slide 10
What has to increase for metamorphism to occur? Temperature and
pressure
Slide 11
What kind of metamorphic rock has its mineral grains arranged
in planes or bands? Foliated
Slide 12
When magma cools quickly, what kind of texture does rock have?
Fine-grained
Slide 13
When temperature and pressure change, what can happen to the
minerals in rocks? They change into minerals that are more
stable.
Slide 14
During the rock cycle, what forms when magma cools? Igneous
rock
Slide 15
What is the process in which water, wind, and heat break down
rock? Weathering
Slide 16
Besides clastic and chemical, what is the other kind of
sedimentary rock? Organic
Slide 17
Besides texture, how else are rocks classified? By their
composition
Slide 18
What do scientists call the rock that is formed when magma
cools below the Earths surface? Intrusive igneous rock
Slide 19
The process in which rocks change shape is called
____deformation _________.
Slide 20
D. the quality of a rock based on size and shape of the mineral
grains
Slide 21
A. process in which sediment is dropped and comes to rest
Slide 22
E. process by which new rock is made from old rock
Slide 23
F. the chemical makeup of a rock
Slide 24
B. process by which sediment is removed from its source
Slide 25
C. naturally occurring solid mixture of one or more minerals
and organic matter
Slide 26
Explain how minerals contribute to rock composition. A mineral
is solid, nonliving, crystal-shaped, and formed in nature, and a
rock is made up of 1 or more minerals. Rock is formed from 1 or
more minerals and can become a sedimentary rock (weathering and
erosion), igneous rock (magma), or metamorphic rock (heat and
pressure).
