Rock cycle
Name the three rocks that are in the rock cycle.
Sedimentary rock, Igneous rock and metamorphic rock.
What is the process for a metamorphic rock to form?
High heat and pressure.
What is the process for a sedimentary rock to form?
Weathering and erosion.
What is the process for an igneous rock to form?
Melting and cooling.
What substance comes out of a volcano when it erupts?
Lava. Lava is a really hot substance that flows out of a volcano when it erupts. When it cools it can turn into igneous rock.
What does the rock cycle mean?
The process of how sedimentary, igneous and metamorphic rocks are formed.
What rock does a metamorphic rock turn into?
Igneous rock.
What rock does a sedimentary rock turn into?
Metamorphic rock.
What rock does a igneous rock turn into?
Sedimentary rock.
What rock sometimes has gas bubbles/hole in it?
Igneous rock. The actual rock name is basalt and the reason is has holes is because if the magma cools to quickly the trapped gas bubbles become frozen as tiny holes in the solid rock. (+500 if you guesses basalt too.)
What does deposit mean?
Earth's materials usually loose sediments or minerals.
In the rock cycle what is the next step after a metamorphic rock is formed for it to turn into magma?
The metamorphic rock melts and turns into magma.
What process does a sedimentary rock have to go through in order for it to turn into a metamorphic rock?
A sedimentary rock must have high heat and pressure for it to turn into a metamorphic rock.
In order for an igneous rock to turn into sediments what process does it have to go through?
The igneous rock has to go through weathering and erosion before turning into sediments.
What does compaction mean?
What does deposition mean?
The process when sediments, soil and rocks are added to a landform or landmass.
We know metamorphic rock is formed by intense heat and pressure, what does metamorphosis mean though?
A change or transformation. In the rock cycle there is a lot of changes and transformations.
What does erosion mean?
The process of eroding or being eroded by wind, water, or other natural agents.
Which igneous rock cools and crystallizes below earth's surface?
(Intrusive or extrusive igneous rock?)
Intrusive igneous rock. The slow cooling allows large crystals to form.
Extrusive igneous rock cools above earth's surface, when it cools quickly they form small crystals.
What does Cementation mean?
Liquid rock that cools rapidly after exposure to the Earth’s atmosphere are fine-grained and called extrusive. What type of rock could this be?
Obsidian is an example of this type of rock.
Where can you usually find metamorphic rocks?
Most of the time you will find metamorphic rocks by mountain ranges where high pressures squeeze the rocks together.
What could rock layers also be called instead of "layers"?
Rock layers are known as strata.
Where can you find igneous rocks?
Most of the time you will find igneous rocks at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
Which rock can contain fossils sometimes?
Sedimentary rock.
