ROCK CYCLE REVIEW

What are the three types of rocks?

• metamorphic, sedimentary, igneous

• igneous, metamorphic, weathering

• crystal, clastic, foliated

• igneous, sedimentary, erosion

Sedimentary rock is formed

• when sediment is weathered and packed

• when sediment is eroded, compacted and cemented

• when sediment is weathered, compacted and cemented

• when sediment is eroded, cemented and crystalized

Magma is

• hot rock

• lava

• molten rock below the crust

• molten rock above the crust

• cooled lava

Weathering is

• clouds and rain

• the breaking down of sediment

• the breaking down of magma

• the breaking down of rock

A rock is

• a hard bustance

• a naturally occurring mixture of minerals

• a naturally occurring mixture of gases

• a naturally occurring solid such as ice

The rock cycle is

• natural steps that form sediment and break it down again

• natural steps that form crystals and break them down

• natural steps that form rock and change it to other forms

• natural steps that break down rock

Metamorphic rock is formed when

• rock is weathered and cemented together

• rock is put under high pressure and heat

• rock is heated and melted and cooled

• rock is put under high pressure and weathering

Lava is

• magma cooled under ground

• magma cooled by pressure

• magma under the crust

• magma above the crust

What is erosion?

• The movement of sediment by wind,water, ice, or gravity.

• The movement of sediment by deposition.

• The movement of metamorphic rock by volcanoes.

• The movement of sediment by wind, rabbits, ice or gravity.

Rocks are classified into 3 types by

• the way they or formed

• their color and texture

• their streak color and where they are

• the way they form in water
