Rock Type
What are the three main types of rocks?
What Igneous, Sedimentary, and Metamorphic.
What is the breaking down of rocks by wind, ice, or water?
What is weathering?
What is the name of an Igneous rock that forms underground?
What is an Intrusive Igneous rock?
These "remains of the past" (like shells or bones) are almost always found in sedimentary rock.
What are fossils?
What two factors primarily turn existing rocks into metamorphic
a) Weathering and erosion
b) Melting and cooling
c) Heat and pressure
d) Cementation and compaction
What is C?
What type of rock is formed from molten material that cools and hardens?
What is Igneous?
What process moves sediments from one place to another?
What is erosion?
What type of igneous rock forms on the surface from cooling lava?
What is Extrusive?
This is the name for the tiny pieces of sand, mud, and pebbles that make up these rocks.
What are sediments?
2. What is the process of changing one type of rock into a metamorphic rock called?
a) Sedimentation
b) Metamorphism
c) Erosion
d) Volcanism
What is B?
What are the two types of weathering?
What are physical (mechanical) and chemical?
What two forces are required to create a metamorphic rock?
What is heat and pressure?
Magma or lava must do this to become a solid rock.
What is Cool or Harden?
This is the process where weight from upper layers squeezes the bottom layers into solid rock.
What is Compaction
Metamorphic rocks form from ___.
What are all types of rocks?
This type of rock forms from bits of rocks, minerals, or organic remains.
What is Sedimentary?
Name a rock and how to is formed.
Igneous (cooled magma/lava), sedimentary (compacted sediments), and metamorphic (altered by heat/pressure).
This is the name for molten rock once it erupts onto the surface.
What is Lava?
This is the "glue" process that sticks sediments together to form a rock
What is Cementation?
As you go further underground, what happens to temperature and pressure?
What is the temp and pressure increase?
A rock was formed by smaller pieces of rock that settled at the bottom of a lake. What type is it?
Sedimentary.
What is the name for molten rocks located beneath Earth's surface?
What is magma?
Rocks formed from magma usually have large crystals because the magma cools at this speed.
What is slowly?
What sedimentary rock is formed from the remains of ancient swamp plants and is burned for fuel.
What is coal?
If a metamorphic rock gets too hot and melts, it is no longer metamorphic; it becomes this.
What is Magma
