Rocks vs Minerals
What is the difference between a rock and a mineral?
Rocks are made of minerals: minerals are natural, non-living substances.
What type of rock forms from cooled lava?
Igneous
What property describes how a mineral reflects light?
Luster
What is a fossil?
The remains or traces of a living thing from long ago
What is mining?
Removing minerals/rocks from the Earth
Are all rocks made of one mineral?
No, rocks are up of multiple minerals
Which rock forms from layers of sediment?
Sedimentary
Can a mineral be made of more than one substance?
No (it has a specific composition)
What type of fossil is a footprint?
Trace fossil
Name one way mining harms the environment
Destroys land / pollution
Is quartz a rock or mineral?
Mineral
Which rock forms under heat and pressure?
Metamorphic
Why might two minerals look the same but be different?
They have different properties
How are fossils formed?
Buried in sediment, minerals replace remains over time
What is one way to reduce mining?
Recycling, practicing eco-friendly habits
Can a rock be made of many minerals?
yes
What process changes rocks from one type to another?
Rock Cycle
Why is hardness a useful test for identifying minerals?
It helps compare and identify minerals
What can fossils tell us?
What life and environment were like long ago
What is one benefit of mining?
Provides materials we use
Name one mineral property used to identify it
Color, luster, streak, hardness
Give one example of each rock type
Igneous (obsidian), sedimentary (sandstone), metamorphic (marble)
Why is color not always reliable?
Different minerals can be the same color
Why do fossils take millions of years to form?
Slow process of burial and mineral replacement
Should we stop mining completely? Why or why not?
