ROCK TYPES
What type of rock forms when magma cools and hardens?
IGNEOUS ROCKS
What process forms igneous rock?
Cooling of magma
What energy source drives weathering?
SUN
What is weathering?
BREAKING DOWN OF ROCKS
What is sediment?
Small pieces of broken-down rock
What type of rock forms from layers of sediment?
SEDIMENTARY ROCKS
What process forms sedimentary rock?
COMPACTION AT CEMENTATION
What energy source melts rock into magma?
ENERGY FROM THE EARTH'S INTERIOR
What is erosion?
MOVEMENT OF SEDIMENTS
What is magma?
Melted rock
Which rock type forms from melted rock?
IGNEOUS ROCKS
What must happen to sediment before it becomes sedimentary rock?
IT MUST BE COMPACTED AND CEMENTED
Which energy source affects rocks at Earth’s surface?
ENERGY FROM THE SUN
Name two things that cause weathering.
Wind and water
What does compaction mean?
Sediment being pressed together
Which rock type forms from compacted and cemented sediment?
SEDIMENTARY ROCKS
Can any type of rock become sediment?
YES
Which energy source affects rocks deep underground?
ENERGY FROM THE EARTH'S INTERIOR
Does weathering create sediment or move sediment?
Create sediment
What does cementation mean?
Minerals gluing sediment together
Why can two rocks with similar minerals still be different rock types?
Because they formed in different ways
Explain the difference between how igneous and sedimentary rocks form.
Igneous rocks form when magma cools; sedimentary rocks form when sediment is compacted and cemented
Why does weathering not happen deep underground?
NO SUNLIGHT, AIR OR WATER
How are weathering and erosion different but connected?
Weathering breaks rock into sediment; erosion moves the sediment
What does the word “energy” mean in rock transformations?
The ability to cause change in rock material
