Rocks and Minerals Unit Review

Rocks are always

• minerals
• solids
• folids
• extrusive

Rocks that have been changed by intense heat and/or pressure are called _______________ rocks.

• sedimentary 
• compound 
• igneous 
• metamorphic 

Which is true of a rock?

• A rock is a type of mineral
• A rock may contain no minerals
• A rock is always made of at least one mineral
• A rock is always made of two or more minerals

A metamorphic rock melts.  This molten rock then cools and becomes solid.  These processes are part of the 

• magma cycle
• pressure cycle
• rock cycle
• metamorphic cycle

The rock cycle 

• ends with igneous rock
• begins with igneous rocks
• ends with metamorphic rocks
• has no beginning or end

The most common type of rock at the Earth's surface is

• igneous
• sedimentary
• metamorphic
• plant-based

Limestone can form when water evaporates and leaves behind the minerals that form it.  Limestone is

• an igneous rock
• a parent rock
• a metamorphic rock
• a sedimentary rock

Wind moves layers of sand along as ancient sand dunes.  These sand dunes were preserved rock.  This is an example of how sedimentary rock can record information about

• past temperature conditions
• past climate conditions
• metamorphic changes
• mineral recrystallization

Rocks that form when layers of sand, silt, clay and mud are pressed and ceremented together are called ________________rocks

• sedimentary
• compound
• igneous
• metamorphic

Your rock sample has parallel bands of minerals that formed under high pressure. Your sample is 

• an unfoliated metamorphic rock
• an unfoliated sedimentary rock
• a foliated metamorphic rock
• a foliated sedimentary rock
