Mesozoic Era Part 2 Study Guide
Vocabulary
Pangaea
all the continents joined together in a gigantic land mass
crust
the outermost layer of earth that varies in thickness from 5-21 miles
mantle
the middle layer of earth located between the crust and the outer core
outer core
layer of liquid metal between earth’s mantle and the inner core
inner core
the solid ball of iron and nickel at the center of Earth
seismologist
a scientist who studies earthquakes
volcanologist
a scientist who studies volcanoes
fault
a break in Earth’s crust where pieces of the crust slip past each other
normal/rift fault
when rocks move away from each other along the surface
reverse/thrust
fault
when rock moves up and over the other side of the fault
strike-slip fault
when rocks move horizontally along the surface
seismograph
an instrument that records and measures the time, size and direction of
an earthquake
magma
hot, molten rock inside the mantle of the earth
Pangaea started to break up about 200 million years ago during the Mesozoic Era.
One way scientists know this might be true is how Africa and South America fit together like
puzzle pieces.
We live on the crust of the earth.
The mantle is the largest layer of the earth and is made of liquid molten rock.
The moving of faults causes earthquakes and volcanoes.
An earthquake is caused by a sudden, violent shift of the earth’s plates.
Volcanoes occur along plate boundaries.
Magma is inside the earth, lava is magma that comes out of a volcano.
The three most common types of volcanoes are: stratovolcano, cinder cone and shield.
