what causes an earthquake
the shaking of the earths crust caused by the sudden release of energy along fault lines
What are waves where the particles move perpendicular to the direction of motion?
Transverse wave
What is the most common type of rock to find in distinct flat layers because it is formed from particles settled by win and water
Sedimentary rock
what is a hypothesis?
(be specific)
the third step in the scientific method where a scientist makes an educated guess that can be tested

What is the law of conservation of energy
energy can neither be created nor destroyed
Instead of crests and troughs a longitudinal wave is characterized by tightly packed compressions and these relaxed spaced out states

on the bottom
what is a scientific theory
an explanation of a phenomenon that has been extensively tested
this rule dictates that only about this percentage of energy is transferred from one trophic level to the next higher level
