Sedimentary Rocks
What are sedimentary rocks made of?
Sedimentary rocks are made of sediment.
What is an example of metamorphic rock?
An example of metamorphic rock is slate.
What is an example of extrusive ingneous rocks?
One example of extrusive igneous rock is pumice.
What is an example of an intrusive igneous rock?
An example of intrusive igneous rock is granate.
What is an example of a sedimentary rock?
An example of sedimentary rock is limestone.
What does metamorphic rock consist (made) of?
Metamorphic rock is a combination of both ignious and sedimentary rock.
What is extrusive ingneous rocks consist (made) of?
Extrusive igneous rocks are made of magma.
True or false? Intrusive igneous rocks are cooled below the Earth's surface.
True. Intrusive igneous rocks are cooled under the Earth's surface.
How would sediment travel into the ocean?
Sediment travels to the ocean by erosion.
Where does the heat source for the formation of metamorphic rocks come from?
The heat comes from magma, to form metamorphic rocks.
What consistency (texture) is extrusive igneous rocks?
The consistency of extrusive igneous rocks are very fine (thin).
True or false? Intrusive igneous rocks are very fine?
False. Intrusive igneous rocks are very thick, and coarse- grained.
True or false. Does sedimentary rock compact from heat and pressure?
False, sedimetary rocks only get compacted from pressure.
What natrual force does the pressure for the formation of metamorphic rocks come from?
The natrual force of Earth's plates moving combines the rock (along with heat), to create metamorphic rocks.
What are extrusive igneous rocks often called?
Extrusive igneous rocks are often called volcanic rock.
True or false? Pressure is involved in the proccess of forming intrusive igneous rocks.
False, pressure is not used to form intrusive igneous rocks. Only magma and cooling underground is used for the proccess of forming intrusive igneous rocks.
How are sedimentary rocks formed?
By weathering and erosion breaking down rocks, creating sediment. The sediment gets formed into layers by pressure, creating sedimentary rocks.
True or false? Metamorphic rock is only formed and held together by the force of pressure.
False. Metamorphic rock is combined and held together by heat and pressure.
True or False? The magma of the extrusive igneous rocks are formed under the Earth's surface.
False. The magma is forced upon the Earth's surface (durring a volcano eruption), and cooled quickly.
How did a rock get to the intrusive igneous rock form on thw rock cycle?
A rock went from metamorphic rock, then melted, then turned into magma, which cooled underground and became intrusive igneous rock.
