Earthquakes

Question 1

Earthquake

Answer 1

Vibrations in the ground that result from movement along breaks in Earth’s lithosphere

Question 2

Fault

Answer 2

Break in Earth’s lithosphere where one block of rock moves toward, away from, or past another.

Question 3

Focus

Answer 3

Place along a fault where rocks firat move in an earthquake

Question 4

Epicenter

Answer 4

The location on Earth’s surface directly above the focus

Question 5

Seismic waves

Answer 5

Energy that travels as vibrations in and on Earth

Question 6

Normal fault

Answer 6

Associated with extensional forces as a result of a divergent boundary, plate moves down. Hanging wall moves down relative to foot wall

Question 7

reverse fault

Answer 7

Associated with compressional forces as a result of a convergent boundary. hanging wall moves up relative to foot wall

Question 8

strike slip fault

Answer 8

a result of transform boundary, strike slip forces, shearing motion

Question 9

secondary wave

Answer 9

S-wave, slower then p-waves but faster then surface waves, only travel through solids, move perpendicular to motion of wave. up and won motion

Question 10

Primary wave

Answer 10

P-wave, fastest wave, first wave, travel through solids and liquids, travel in same direction as motion, side to side motion.

Question 11

surface wave

Answer 11

Slowest seismic wave, causes the most damage, travels in a rolling motion

Question 12

richter scale

Answer 12

Measures the largest jolt of energy, determined by the height of the waves on the seismograph. 1-9

Question 13

Mercalli scale

Answer 13

A scale of earthquake intensity ranging from 1-12 in roman numerals ,chosen by what people felt felt or damage caused
