Which one is bigger (wider), crater or caldera?
Give this one a try later!
caldera
Know how to determine the age of a sample and use the radio active decay curve
Give this one a try later!
(half life) x (number of half lives) = age
example: (1,000 years) (1 year) = 1,000 years is 50% parent, the x value is 1
and the y value is 50
example: (1,000 years) (3 years) = 3,000 years is 12.5% parent, the x value is
3 and the y value is 12.5

Give this one a try later!
, unconformity is a gap between rock layers
Explain the concept of inclusions
Give this one a try later!
a piece of a rock that is caught up inside of another rock
What are pyroclasts?
Give this one a try later!
any volcanic fragment that was hurled through the air by volcanic activity
List all the properties of cinder cones.

- smaller
- steep slopes
- deep crater (height < 300m)
- pyroclasts and sometimes lava from the sides
- clusters
