What are Rocks and Minerals?
Rock Cycle
Rock / Mineral Properties
Mining & Fossils
10
Name a type of rock:
AMV
10
What is a sedimentary rock?
When sediments, such as sand or shells, compresses together and forms a rock
10
How would you describe what this rock looks like?
AMV
10
What might we mine for?
Gold, silver, salt, granite, marble, etc.
20
What examples of minerals can you think of?
Gold, silver, copper, diamond, quartz
20
What is an igneous rock?
When lava cools it becomes an igneous rock
20
Name a property you can describe of rocks or minerals?
magnetism, transparency, hardness, lustre, streak, colour
20
What is a fossil?
Preserved remains of plants and animals that were once living on Earth
30
How would you define what a rock is?
A rock is a solid material that is a lump of minerals that grow or are fused together.
30
What is a metamorphic rock?
When another type of rock undergoes a high temperature and high pressure
30
How are rocks formed?
By nature - different processes depending on the type of rock
30
What is mining?
Mining is when rocks and minerals are extracted from the earth
40
Name one example of how a rock and mineral is used in everyday life?
Example:
limestone is used to make concrete
gold is used for jewelry
40
Can you give a simple explanation of the rock cycle?
Lava cools = igneous rock
Erosion to igneous rock = sediment
Sediments compress = sedimentary rocks
Sedimentary rock has high temp and pressure = metamorphic rock
Metamorphic rock may melt = magma
40
How could you use physical properties you can see to describe the following mineral:
Colour - turquoise, blue, green, clear, black
Transparency - slightly transparent on some parts
Lustre - reflects like diamond at some points, or waxy at other points
Looks like crystals stuck together
40
______ are studied by paleontologists to learn about Earth's history?
hint: they are found in rocks
Fossils
50
Explain the difference between a rock and a mineral:
A mineral is a pure substance and a rock is made up of two or more minerals and materials
50
Name the three types of rocks and how they are formed:
Igneous - when lava cools
Sedimentary - when materials get compressed in layers
Metamorphic - from high temperature and pressure
50
Name 3 physical properties of a mineral:
magnetism, transparency, hardness, lustre, streak, colour
50
What is a pro and con of mining?
Pro - gives us minerals and resources that we use for many different buildings and objects
Cons - causes pollution, destroys animal homes
