A Rock
This is molten rock found below the earth's surface.
What is magma?
tiny pieces of rock, sand, shells, etc. is called what
What is sediment?
Metamorphic rocks are formed due to _______ and _______.
Heat and Pressure
When sediments undergo compacting and cementation processes, they become which type of rock.
Sedimentary rocks.
Weathering and Erosion
The physical properties of slow-cooling Igneous rocks have...
Slow cooling and many colors.
Examples of Sediments
Broken down pieces of rock,
Sand
Soil
True of False- Metamorphic rocks can change in size and shape.
True- due to intense heat and pressure
Undergoing weathering and erosion, will show which type of rock?
Sedimentary
Difference between magma and lava.
Magma when is underground, lava after errupts.
This type of rock is found near volcanoes or fissures.
Igneous
Sedimentary rocks are formed by...
Compaction & Cementation
Minerals can be added or substracted due to transformation. True or False
True
The rock cycle is continuous. True or false.
True.
The only type of rock that contains fossils.
Sedimentary
Fast cooling Igneous rocks have these physical properties...
Glassy and have holes
Which types of rock can become sedimentary rock?
ALL (Sedimentary, Igneous, Metamorphic)
Difference between time it takes to form igneous and sedimentary rocks.
Igneous rocks take from days to thousands of years to form, sedimentary rocks take millions of years.
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
Heat and pressure
Give three properties you would use to describe a rock.
Answers may vary (colour, hardness, size of crystals, layered/non-layered, banded/not-banded, air bubbles, glassy, shiny/dull)
What processes help form Igneous rocks?
Cooling & Hardening
Weathering (breaking down of rocks in sediments) can be_____, _______and_____ . Give two types of weathering.
Mechanical (due to atmospheric processes such as rain, wind, freeze/thaw).
Chemical, due to chemical reactions between rocks and acid rain, water or different types of rocks.
Biological (plants, animals).
These rocks have ribbon-like layers and may have crystals.
Metamorphic
True or false: Any type of rock can become any other type of rock.
True
Igneous rocks are formed from cooled__________
