Volcano
DOUBLE POINTS
What is lava called when under the Earth?
Magma
What is the epicenter?
The epicenter is where we see the earthquake on the Earth.
What is the lithosphere made of?
Crust and upper mantle
What part of the Earth are the tectonic plates located?
On the lithosphere
Which layer of Earth do we live on?
We live on the crust.
What do you get when you mix water and magma?
Explosive volcanic eruption
DOUBLE POINTS
How do we measure earthquakes?
We measure earthquakes using seismographs.
What is the “sphere” under the lithosphere?
Asthenosphere
How do you find the epicenter?
The epicenter is found by measuring the magnitude of where the earthquakes meet.
What does every scientist use?
Every scientist used the scientific method
What type of rock is found near volcanoes?
Igneous Rock
What’s the difference between the focus and epicenter?
With earthquakes the epicenter is on the crust, and the focus is where the earthquake begins under the Earth.
What’s the difference between tectonic movement and continental drift?
Continental drift is the theory that continents move apart, whereas tectonic plates are piece of the entire Earth that move.
DOUBLE POINTS
Name the 3 types of plate tectonic boundaries.
Convergent, Divergent, transvergent
What are the different “Zones” of the Earth?
-Tropic Zone (Tropic of Cancer, Tropic of Capricorn)
-Temperate Zones
-Polar Zone
What makes volcanoes eruption explosively?
A buildup of pressure makes volcanoes erupt explosively.
What is a tsunami?
A tsunami is a huge wave caused by an earthquake.
What can earthquakes cause?
Earthquakes can cause tsunamis and liquefaction.
What is Alfred Wegener’s theory?
Alfred Wegener made up the theory of Pangaea. Pangaea was the super continent, where the continents then drifted apart.
What two things make up the Earth?
Physical processes and human activity make up the Earth
How does water/silica make an explosive volcanic eruption?
Water acts as a gas when mixed with magma, leading to an explosive volcanic eruption.
Too much silica in volcanoes leads to a clog at the vent of the volcano. The buildup of pressure causes the explosive volcanic eruption.
What is the relationship between the frequency of seismographs and earthquakes?
When reading the magnitude of an earthquake, the more frequent the needle moves to measure the seismic waves, the more intense the earthquake.
Where exactly are the tectonic plates located again?
The tectonic plates are in the lithosphere (Crust and Upper Mantle) and the asthenosphere (Mantle).
Name 3 major and minor tectonic plates
Major:
Pacific Plate North American Plate ,
Eurasian Plate African Plate
Antarctic Plate –Indo-Australian Plate
Australian Plate Indian Plate
South American Plate
Minor:
Somali Plate –Nazca Plate Philippine Sea Plate
Arabian Plate Caribbean Plate
Cocos Plate – Scotia Plate –
Draw the Rock Cycle. Name the parts.
Igneous, Metamorphic, Sedimentary rock are the 3 parts of the rock cycle.
