The Rock Cycle🪨
What is igneous rock?
Igneous rock is magma/lava when it cools and hardens.
What type of volcano has very explosive eruptions?
Composite volcano.
What is the epicenter?
The epicenter is directly above the hypocenter.
What is The Ring of Fire?
The Ring of Fire is a region where there is frequent seismic activity.
Minerals are made of...
Inorganic material
How many times can this cycle repeat itself?
There is no limit to this cycle, it can go on forever.
How do volcanoes happen?
Volcanoes happen when a convergent or divergent boundaries then rifts or cracks form due to plate movement and then there is a spot where magma boils and gets pushed to the surface.
What is a fault?
A fault is a crack in the Earth's crust.
True or False; Can the result of an earthquake be a tsunami?
True
What does organic mean?
Are sediments the same thing as sedimentary rock? Why or why not
No; Sediments are broken up pieces of rock and sedimentary rock is when it all compacts together.
What is a volcano?
A volcano is a cone shaped hill or mountain that is formed when hot magma, solids and gasses erupt through Earth's surface through a vent.
What is an aftershock?
An aftershock is a small unpredictable earthquake that comes after a bigger one.
True or False;A tsunami is just 1 wave.
False; A tsunami is a series of waves.
Diamonds are created by WHAT cooling into kimberlite?
MAGMA
What does weathering and lithification mean and what can it do to igneous rock?
It means that rock (igneous rock) breaks down into pieces . It turns igneous rock into sediments.
How do scientists know when a volcano is going to erupt?
There are many different ways but here are a few, they study the length of time between eruptions, they study the gas emitted, they monitor the magma rising...
What's the difference between a seismograph and a seismogram?
A seismograph measures the amount of energy released by an earthquake and a seismogram records the data that details the magnitude of the waves and how long the waves lasted.
What is a tsunami?
A tsunami is when earthquake or volcanic eruptions happen and cause the water to form destructive waves that can wipe out shorelines.
Inorganic material is naturally found in where?
It's naturally found in nature.
How many steps (types of rocks) are there in the rock cycle? What are they?
5; Igneous rock, sediments, sedimentary rock, metamorphic rock and magma.
What is an active, dormant and extinct volcano?
Active=currently erupting or showing signs of eruption soon.
Dormant=no current activity but has erupted recently
Extinct=no activity for a while and no signs of activity soon
True or false, are all earthquakes felt?
False; some earthquakes are so small they are not felt.
True or False; You can always feel an tsunami no matter where it is in the ocean.
False; A tsunami can be up to q1-3 feet when it first starts to form.
What does clarity and luster mean?
Clarity=how clear the gem is
Luster=how the mineral reflects light (shininess)
