Rocks and Mineral
In what type of rocks are most fossils found?
Sedimentary Rocks
Are rocks made up of minerals? or Are minerals made up of rocks?
Rocks are made up of minerals
What shows how rocks change from one form to another form of rock?
Rock Cycle
What type of rocks are formed when sediments are cemented and pressed together?
Sedimentary Rocks
What is a natural, nonliving substance that makes up rocks?
Mineral
A type of rock that forms from melted rock that cools and hardens.
Igneous rock
This process involves wind, water, and ice moving rocks.
erosion
Rocks materials are moving through the rock cycle all the time. True or False?
True
What types of rocks form when magma cools and hardens?
Igneous Rocks
What are the 3 types of rocks called?
What do we use Moh's scale for?
To test how hard a mineral is
What is a rock?
Minerals and other material including organic material that are fused together.
During the rock cycle, how can a rock change into a igneous rock?
Any rock can melt into magma, and then cool and crystallize to form an igneous rock.
What types of rocks are formed from extreme heat and pressure?
Metamorphic Rocks
What is the hardest mineral?
Diamond
what is a crystal?
A crystal is a solid whose atoms are arranged in a "highly ordered" repeating pattern.
This process allows wind, water, and ice to break apart rocks.
weathering
How can some rocks become metamorphic during the rock cycle?
Heat and Pressure
Can more than one mineral share the same properties?
No, each mineral has its own set of properties. No two minerals have the same set of properties because their chemical composition is different.
Name 4 properties of identifying minerals.
-color -luster- -steak -hardness- density-cleavage/fracture-color
What is the role of plate tectonics in the rock cycle? How does is contribute to the formation of igneous, sedimentary, and metamorphic rock?
Plate movements on the sea floor help to form magma, which is the source of igneous rock. The collision of continental plates also forms mountains which can weather and erode away into sediment. Finally a collision of plates can push rocks down beneath the surface where they experience heat and pressure to form metamorphc rock.
Dropping weathered rock by wind or moving water in a location. (commonly at the bottom of a source of water).
Deposition
In the rock cycle, what breaks rocks into sediments and carries them away?
Weathering and Erosion
What is the difference between intrusive and extrusive igneous rocks?
Intrusive-in or under the ground
Extrusive-on or above the ground
Name the five characteristics that identify minerals
solid, inorganic, naturaly occuring, definite chemical composition, crystalline structure
