100
A rock made from the compaction and cementation of smaller pieces of rock.
What is a sedimentary rock?
100
The supercontinent formed when all continents were connected.
What is Pangaea?
100
This is melted rock INSIDE the earth.
What is magma?
100
The slowest, most damaging seismic wave that can travel up-and-down or side-to-side.
What is a surface wave?
100
The age of Earth.
What is 4.6 billion years old?
200
A rock made when heat and pressure are added to a pre-existing rock.
What is a metamorphic rock?
200
The crust and upper part of the mantle make up this layer of the earth.
What is the lithosphere?
200
Slow flowing, thick lava is said to have a _______ viscosity.
What is high?
200
Underwater earthquakes are the main cause of these high sea waves.
What are tsunamis?
200
Most of Earth's crust is made up of this rock. (One of the three types)
What is igneous rock?
300
An igneous rock containing large crystals. (Intrusive or Extrusive)
What is intrusive?
300
The rock type that makes up oceanic crust.
What is basalt?
300
This type of volcano has broad, gently sloping sides. It's known to have quieter eruptions.
What is a shield volcano?
300
The San Andreas Fault is an example of this type of fault.
What is a transform fault?
300
This type of crust is older, thicker, and less dense.
What is continental crust?
400
The principle that states older rocks are located on bottom and younger rocks are located on top.
What is the principle of superposition?
400
In seafloor spreading, the youngest rock would be found here.
What is near the ridge?
400
The number one killer of volcanoes? (Lava, earthquakes, pyroclastic flow, heat lightning)
What is pyroclastic flow?
400
The type of stress causing a normal fault?
What are tension?
400
A trench would be found at this plate boundary.
What is a convergent boundary (subduction)?
500
A rock made when oceanic crust melts at a subduction zone and then solidifies.
What is an igneous rock?
500
The plate boundary where the tectonic plates move at the quickest rate (speed).
What is subduction?
500
Tall mountains that are formed from alternating layers of pyroclastic material and lava.
What are composite volcanoes?
500
The seismic waves that can travel through solids, liquids, and gases (through Earth's core).
What are primary waves (P waves)?
500
The four eras of Earth's history in order from youngest to oldest.
What is cenozoic, mesozoic, paleozoic, and precambrian?
