Identifying Minerals
Types of Rocks
100
The hottest layer of Earth, in its center
What is the core?
100
A type of weathering in which rocks are broken down by the actions of chemicals.
What is chemical weathering?
100
This is the movement of materials away from one place. Examples: wind, landslides, waves, etc.
What is erosion?
100
This is a scale used to test the hardness of a mineral.
What is the Mohs scale?
100
Rocks that form when layers settle on top of each other.
What is sedimentary rock?
200
The thin, outside layer of Earth
What is the crust?
200
A type of weathering that causes rocks to break apart.
What is mechanical weathering?
200
This is the placing of materials in a new place. Ex: sand dunes
What is deposition?
200
The way a mineral feels: sticky, smooth, powdery
What is texture?
200
The layers at the bottom of a rock are _________ than those at the top.
What is older?
300
An inner layer of Earth made of solid rock that bends and moves like a liquid from heat and pressure
What is the mantle?
300
Mechanical weathering and chemical weathering help to make this.
What is soil?
300
These cause erosion by pulling large rocks or boulders along a valley and eventually grinding them into sediment.
What are glaciers?
300
A natural solid whose particles make a pattern.
What is a mineral?
300
These form when melted rock cools and hardens.
What is igneous rock?
400
The difference between oceanic and continental crust
What is: the oceanic crust is the ocean floor and the continental crust is the continents.
400
Give an example of chemical weathering OR mechanical weathering - you must say the type and the example.
Teacher discretion allowed.
400
This is a source of erosion that happens along coastlines.
What are waves?
400
This is the way a mineral reflects light.
What is luster?
400
When solid rock is heated and squeezed, changing the properties of the rock.
What is metamorphic rock?
500
A tool scientists use to measure earthquakes.
What is a seismograph.
500
This layer of soil is almost solid rock.
What is bedrock?
500
This is the main force causing erosion.
What is gravity?
500
The powder that is created when a mineral is rubbed on a hard surface to see it's color.
What is a streak?
500
Rock layers can help scientists determine the age of these.
What are fossils?
