What is an Earthquake?
A release of energy.
100
What is topography?
It is a map of the shape of the land
100
How are rocks classified?
By how they form.

400
How do we detect and locate earthquakes?
Seismographs
400
What are contour lines?
They are lines connecting points & show the elevation.

What is soil?
It is a mixture of water, air, organic and mineral matter.
600
What is a subduction zone?
Subduction occurs when an oceanic plate runs into a continental plate and slides beneath it.
600
What is the difference between Foreshock and Aftershock?
A foreshock is a small earthquake that happens before the actual earthquake, and an Aftershock is also a smaller earthquake or shaking that happens after the earthquake.
600
What is the contour interval?
It's the difference in elevation between each line. Equal spacing.
600
What is the difference between Mechanical and Chemical weathering?
Mechanical is physicl breakdown and changes in size, while chemical changes the composition of a rock.
600
What percentage of Mineral matter does soil have?
45%
800
What is the difference between the Oceanic crust and the Continental crust?
The Oceanic crust is denser than the Continental crust.
800
What is the difference between S-waves, P-waves, and L-waves?
P - fastest
S- 2nd fastest
L- slowest
800
4 rules of contour lines?
1. They never cross each other.
2. Always form closed loops.
3. Will bend upstream/uphill when crossing a river.
4. The max elevation for a hill is -1 of the next contour line.
800
List all Chemical Weathering types
Oxidation
Carbonation
Hydrolysis
Acidification

What are the different textures of soil?
Sand, Silt, & Clay
1000
What are the three types of stress and what plate boundary causes each of them?
Tension - Divergent
Convergent - Compression
Transform - Shearing
