One kind of rock can change into any other kind of ___________.
What is rock

What are the 2 types of weathering?
What are physical and chemical
100
These are the 3 types of rocks
What are igneous, metamorphic, and sedimentary

A mineral has ________________ if it is attracted to a magnet.
What is magnetism
200
This property does not always help identify a mineral because the mineral can come in a variety
What is color
200
Sedimentary and igneous rocks can become metamorphic rocks by ____________________.
What is heat and pressure
200
This is when rocks break into smaller pieces without changing what the rock is made of
What is physical weathering
200
How would a scientist test if a rock contains calcite?
A scientist can test a rock for calcite by applying acid. If the rocks shows a reaction of fizzing, it contains calcite
200
These types of rocks contain fossils
What are sedimentary rocks
300
A mineral has ________ if it breaks into clean, even slices; a mineral has ___________ if it breaks into uneven, crumbly, or round pieces.
What is cleavage and fracture
300
Igneous and metamorphic rocks can become sedimentary rocks by ____________.
What is weathering
300
This is what happens when rocks exposed to chemicals in the water or air turn into new substances
What is chemical weathering
300
Give 1 example of each type of rock: igneous, metamorphic, sedimentary
igneous: obsidian, granite, pumice sedimentary: limestone, sandstone metamorphic: marble, quartzite

What is the difference between and rock and a mineral?
Minerals are pure substances from the earth. A rock is made of different minerals.
400
This is a mark of mineral powder
What is streak
400
Metamorphic and Sedimentary rocks can become igneous rocks by ______________.
What is melting
400
What is the difference between chemical and physical weathering?
Physical weathering is caused by physical interactions with the rock (abrasion, water freezing, wind sand blasting, force of trees roots etc.) Chemical weathering is caused by chemical reactions with the rock surface (acid rain, pollution in the air, ultraviolet sun light, etc.)
400
How do metamorphic rocks form?
Metamorphic rocks change from one existing rock to another rock because of heat and pressure
400
Layers of sand are called_____________
What is sediment
500
This describes the way light reflects off a mineral. Minerals can be described as ____________ or ______________.
What is luster. Non-metallic and metallic.

500
Give 2 examples of physical weathering and 2 examples of chemical weathering
Physical weathering: abrasion, freezing, tree roots, wind Chemical: pollution in the air, acid rain
500
How do sedimentary rocks form?
Sedimentary rocks form from bits and pieces of other rocks and minerals. Overtime these pieces are pressed together with pressure and form sedimentary rocks.
500
How do igneous rocks form?
Igneous rocks start out as melted rock (magma). This magma can pour out of the earth. When the magma cools and hardens it forms a new igneous rock
