Geologic Time
Rocks and Minerals
100
Two plates moving towards each other (example: The Ring of Fire)
Convergent Plate Boundary
100
This is molten, liquid rock on the surface of the crust
Lava
100
A state that is famous for its large amount of earthquakes
Alaska or California
100
Name an example of a geologic time period
Quaternary, Neogene, Paleogene, Cretaceous, Jurassic, Triassic, etc.
100
True or false: Every type of rock can become the other two types of rock
True
200
Two plates moving away from each other (example: The Mid-Atlantic Ridge)
Divergent Plate Boundary
200
Where most volcanoes in the world are located
The Ring of Fire
200
The overall strength of an earthquake, as measured on a scale such as the Richter
Magnitude
200
Name which rock layer is the youngest, and which is the oldest.
A and I
200
Do rocks contain many minerals, or do minerals contain many rocks?
Rocks contain many minerals
300
This is what causes plates to move (hint: it involves a layer of Earth!)
Convection currents in the mantle
300
This is the type of rock that gets made by volcanoes
Igneous
300
How strongly an earthquake is felt in one particular location, and the damage it causes in that spot
Impact
300
How much of a substance is changed after 1 half life has gone by?
Half!
300
The type of rock that is made from small pieces forming together over time
Sedimentary rock
400
This is what Alfred Wegener is famous for discovering
Continental Drift
400
The two types of plate boundaries where we see volcanoes
Convergent and Divergent
400
Where do most of the earthquakes in the world happen?
The Ring of Fire
400
Comparing the age of things around an object in order to guess the age of the object itself
Relative Dating
400
Describe how metamorphic rock is formed
The other two types of rock go underground and experience heat and pressure, which changes them to metamorphic rock
500
When one plate moves UNDER another plate and into the mantle
Subduction
500
Name the three states that we classify volcanoes in based on their past/future eruptions
Active, Dormant, Extinct
500
What causes an earthquake
The plates either colliding or scraping past each other at a fault line
500
The two elements that are most commonly used in absolute dating
Carbon-14 (carbon) and Uranium-238 (uranium)
500
What is the difference between weathering and erosion?
Weathering is when wind/weather chip off small pieces of rock
Erosion is when they get carried away
