What are the three types of rocks?
What are Sedimentary, Igneous and Metamorphic rocks?
100
These two processes are responsible for the formation of metamorphic rocks.
What are heat and pressure?
100
These processes show how sedimentary rocks form.
What is weathering, erosion, compaction and cementation of sediments?
100
Igneous rocks form this way.
What is the cooling and crystallization (solidification) of magma?
100
This describes the weathering process.
What is the breaking down of all rocks?
200
This is the way that rocks are grouped or categorized.
What is how do different kinds of rock form?
200
This metamorphic rock forms when granite is exposed to tremendous heat and pressure. It also shows foliation.
What is gneiss?
200
This kind of sedimentary rock forms by particles of rock cementing together. Sandstone and shale are examples.
What are clastic sedimentary rocks?
200
Igneous rocks that form here cool slowly and have large crystals. An example of this kind of rocks is __________.
What are intrusive igneous rocks? What is granite?
200
Once rock is weathered, it is moved by water, wind or ice. This process is
What is erosion?
300
When two plates converge with a subduction zone, these 2 kinds of rock form
What are igneous and metamorphic rocks?
300
This is a feature of metamorphic rock that shows long banding (lines) of particular crystals.
What is foliation?
300
This type of sedimentary rock forms from evaporation of water from a solution. Halite (salt) is an example.
What is a chemical sedimentary rock?
300
This kind of igneous rock forms on the surface and cools quickly. Its crystals are fine (small) and __________ is an example of this kind of igneous rock.
What are extrusive igneous rocks? What is basalt or rhyolite ?
300
Our rock shaking lab represented this mechanical weathering process where rocks scrape and grid against each other.
What is abrasion?
400
At divergent plate boundary, magma rises to the surface to form _______________ rocks.
What are igneous rocks?
400
Since metamorphic rocks are formed from intense heat and pressure, they tend to be more packed with matter which makes them ___________.
What is more dense?
400
If the bottom layer of sedimentary rock is mudstone, the second layer contains fossils, and the top layer is sandstone. Which sediment (or layer) is oldest?
What is mudstone? (The lowest layer is the oldest.)
400
This is the first step for a sedimentary rock to become an igneous rock.
What is melting?
400
Limestone contains calcite and is easily weathered by acid in rain. This kind of weathering is ________
What is chemical weathering?
500
These two sources of energy for Earth form these three types of rocks. _______________ is the source for sedimentary rock, ________________ is the source for igneous and metamorphic rocks.
What are Earth's internal heat and the sun? The sun is the source for forming sedimentary rock and earth's internal heat forms igneous and metamorphic rocks.
500
If the bottom layer of sediment is mud, the second layer contains a fossil, and the top layer is soil. Which sediment (or layer) is older than the fossil?
The layer of mud (bottom layer).
500
Because sedimentary rock forms on Earth's surfaces, imprints of living things form.
What are fossils?
500
These two types of magma form different types of igneous rock . _____________ magma has more silicon and feldspar in itand is lighter in color. _______________ magma has more magnesium and iron in it and is darker in color.
What are felsic and mafic?
500
As a rock breaks into more pieces, it weathers more because _____________________________.
What the surface area increases so there is more rock to be weathered.
