Q.
A type of Metamorphic rock that was once shale rock formed by heat and pressure.
8

Q.
A sedimentary rock formed by the deposition of successive layers of clay.
9

Q.
Interesting rock composed of the remains of plants that lived in tropical swamps millions of years ago. Can be lower quality (sedimentary) or be acted upon by heat and pressure (metamorphic).
10

Q.
rock that forms as molten rock cools
11
120 sec
Q.
rock that forms as heat and pressure cause changes to an existing rock
12
120 sec
Q.
This rock type forms as loose materials called sediments become cemented together. Usually, these rocks have layers.
13

Q.
Rocks that have been buried are exposed at Earth's surface because forces inside the Earth pushing them to the surface.
14

Q.
little pieces of weathered rock, plant remains, and animal remains
15

Q.
These two forces work together to transform rocks deep inside Earth's crust.
16
120 sec
Q.
This is the breaking down of rocks. It can be caused by wind, rain, ice, or gravity.
17

Q.
This causes the most erosion in dry areas that get little rainfall.
18
120 sec
Q.
This is the process that forms igneous rock.
19
120 sec
Q.
This is a coarse-grained, foliated metamorphic rock. It usually contains the minrals feldspar, quartz, and mica.
20
120 sec
Q.
This is a very hard, crystalline, intrusive igneous rock. It is made mostly of quartz, mica, and feldspar. It is often used in counter tops and building materials.
21
120 sec
Q.
This is a dark, porous, volcanic rock. Most of the ocean floor is made of this rock.
22
120 sec
Q.
This is a sedimentary rock consisting of sand grains cemented together, typically red, yellow, tan, or brown in color.
23
120 sec
Q.
This is a sedimentary rock, composed mainly of seashells and calcium carbonate. It is used to make cement.
24
120 sec
Q.
This is a hard metamorphic rock formed from limestone, typically white in color. It is used in sculpture and architecture.
25
120 sec
Q.
This igneous rock formed underground as magma cools slowly. Because it cools slowly, the crystals inside the rock grow very large.
26
120 sec
Q.
This igneous rock forms as erupted lava cools quickly on Earth's surface. Because it cools so quickly, these rocks have very, very tiny crystals.
27
120 sec
Q.
This is the remains or impression of an ancient organism. These are only found in sedimentary rock (not igneous or metamorphic).
28
120 sec
Q.
Most sedimentary rocks form in layers known as ________.
29
120 sec
Q.
found in most rocks, this is the most common mineral in Earth's crust. It forms as lava or magma cools.
30
120 sec
Q.
how a rock looks and feels; determined by grain size, rate of cooling and composition
31
120 sec
Q.
slower rate of cooling causes this; Larger crystalline grains
32
120 sec
Q.
faster rate of cooling causes this; smaller crystalline grains
33
120 sec
Q.
mixture of fine and coarse grain
34
120 sec
Q.
crystal unable to form; Rapid rate of cooling prevents crystals from forming
35
120 sec
Q.
a type of igneous rock in which bubbles formed inside the rock due to a extremely rapid rate of cooling which traps gases inside
36

Q.
process which turns sediment into sedimentary rock; compaction and cementation
41
120 sec
Q.
when hot magma moves into a chunk of rock, heats it up, and hardens again; results in large scale mineral changes with little deformation
