The meteorological equator
What is intertropical convergent zone (ITCZ)
400
Steno's laws only apply to these rocks
What are sedimentary rocks
400
When a wave (i.e., seismic) cannot enter a new medium (material) because its trajectory is too low of an angle.
What is reflection?
400
Material carried by a stream that does not change with velocity
What is dissolved load
400
When the poor space of sediment becomes completely saturated with water
What is liquefaction
400
A pile of material deposited in front of a 'paused' glacier

This explains why earthquakes on the West Coast do not travel as far as earthquakes on the East Coast (of comparable magnitudes).
What is 'hard rock' (east coast) or What is unconsolidated sediments (west coast)
500
This is the maximum load of solid particles a stream can carry
What is capacity
500
Small amounts of 'this' can make sediments more stable but large amounts of 'this' can entirely destabilize a slope and lead to failure
