Answer Key
1.) A naturally occurring solid mixture of one or more minerals or organic
matter.
2.) An inorganic, naturally occurring substance that is the same throughout.
3.) Preserved remains of once living organisms
4.) Igneous, Sedimentary, and Metamorphic
5.) A rock is made up of one or more minerals.
6.) When “magma”cools and hardens “below”
7.) When “lava”cools and hardens “above”
8.) By Erosion when rock layers are cemented and compacted
9.) Layers of rock (associated with Sedimentary Rocks)
10.) The process in which Sedimentary Rocks are arranged in layers.
11.) Sedimentary rocks made up of fragments of rocks
12.) Sedimentary rocks made up of fossils and other remains piled up in layers
13.) Sedimentary rocks formed when water evaporates and leaves behind
hardened minerals.
14.) Regional Metamorphism – pressure builds up in rocks that is deep within
the Earth
Large pieces of the Earth’s crust collide and the rock is deformed and
chemically changed by heat and pressure
15.) When rocks are heated by nearby magma
16.) From heat and pressure
17.) Energy can neither be created or destroyed
18.) Sedimentary Rocks
19.) Magma
20.) Clues
a. Give clues about organisms that lived long ago
b. Understand how the Earth’s Surface has changed.
c. Understand what past environments were like.
21.) Petrified, Molds and Casts, Carbon Films, Trace Fossils, Preserved Remains
22.) Ice, Amber, and Tar
23.) Animal is buried, more sediment piles on top of the animal, movement of
plates push fossil closer to the surface, and erosion will eventually expose the
fossil.
24.) Carbon
25.) Shows the activities of organisms.
