100

How an igneous rock forms

Forms when magma or lava cool and harden

100

How magma is formed

When rock is melted at a high enough temperature

100

What is deposition

When sediments are deposited, usually at the bottoms of lakes, rivers, etc. and they then can begin to form new rocks

100

What is the Mohs scale

100

What is a mineral (at least 2 things)

- Naturally (re)occuring

- Inorganic

- Must be solid

- Have a definite chemical composition

- Have an ordered internal structure (crystal)

200

How a sedimentary rock forms

Forms when layers of sediments become compacted and cemented together

200

How sediments are formed

When rock gets weathered, eroded, deposited

200

What is erosion

When rocks/sediments get moved from place to place
200

One household item that contains minerals

Toothpaste, pots and pans, mirrors, electronics, etc.

200

The hardest mineral in the world

Diamond
300

How a sedimentary rock forms into a metamorphic rock

When the sedimentary rock becomes heated and pressurized within the earth

300

How metamorphic becomes igneous rock

When metamorphic rock melts and cools

300

This is the oldest layer in sedimentary rocks

The bottom layer

300

What is streak

300

The six properties of a mineral

Colour, streak, lustre, cleavage, fracture, hardness

400

How an igneous rock becomes a sedimentary rock

When the igneous rock becomes weathered and eroded, then deposited and eventually cemented

400

Which kind of rock takes the longest to form

Sedimentary because of all the layers and compaction needed

400
How a metamorphic rock forms
400

Bonus: what is uplift?

400

Hardness of a mineral

How easily it can be scratched

500

The difference between an intrusive and extrusive rock

Intrusive - forms underneath the surface; magma

Extrusive - forms above the surface; lava

500

The type of rocks that fossils form in

What is sedimentary rock
500

What is a parent rock and a daughter rock?

Parent rock - the original rock that turns

Daughter rock - what the parent rock turns into

500

Bonus: Where fossils get trapped

Sedimentary rock

500

Difference between cleavage and fracture

Cleavage - breaks into two smooth surfaces

Fracture - breaks into rough uneven surfaces
