Both
Igneous, metamorphic, and sedimentary.
Define luster
The way the light reflects on the mineral. (Shine)
Fossils are an example of which type of rock?
Sedimentary
The breaking down of rock by various agents on earth.
Weathering
Spell out the three main rock types on the white board.

Define streak
Describes the color of the powder the mineral leaves behind when it is rubbed on a streak plate (porcelain tile).
Glaciers are melting due to the rise of global warming. What is this an example of?
Weathering
This is an example of what?
Erosion
glassy
gas bubbles
crystals when cooled slowly
These are characteristics of which type of rock?
Igneous
A scientist decided to grab a hammer and smash a diamond (a very crazy scientist) and a piece of copper. What is he testing for?
Cleavage
Wind, solar, and water are examples of...?
Renewable resource
What is the complete definition of erosion?
The moving of sediment (rock) to new places by various agents on earth.
What is the difference between igneous and metamorphic rocks?
Igneous is firmed when lava melts then cools. Metamorphic is the melting of rocks under extreme heat.
Gemstones or jewelry
How are metamorphic rocks formed?
Forms deep in the earth when rock is put under extreme heat and pressure
Wind carries small pieces of rock away from a mountain.
Igneous near volcanoes.
Sedimentary near water or in deserts
Metamorphic deep in the earth
How does the rising of magma result in the formation of minerals and rocks?
as magma rises towards the earth's surface, it will begin to cool & form solid minerals as part of igneous rocks
