Earthquakes are visible signs of plate tectonics. Earthquakes are caused when there is a sudden shifting of the plates. The effects of earthquakes will vary from region to region depending upon the size of the quake. Whatever their size, they can cause a dramatic change to the Earth’s surface.

1. Earthquakes cause a series of waves called?
[ ] Seismic waves
[ ] Tsunamis
[ ] Tidal waves
[ ] Electro-magnetic pulses
2. What is the Epicenter?
[ ] Where two plates collide
[ ] The measurement of a fault line
[ ] The closest location to the center of an earthquake
[ ] A tourist attraction at Disney World
3. What instrument is used to measure the size and duration of an earthquake?
[ ] Magnitude Scale
[ ] Mercalli Scale
[ ] Telescope
[ ] Richter Scale
4. What is a fault?
[ ] A break in the rocks that make up the Earth’s crust
[ ] Where two plates come together
[ ] Where seismic activity is recorded
[ ] A bulge in the Earth's surface
5. What are three main causes of earthquakes?
[ ] Volcanoes, movement of the tectonic plates, tsunamis
[ ] Volcanoes, the moon’s gravitational forces, tectonic plate movement
[ ] Volcanoes, the sun’s gravitational forces, tectonic plate movement
[ ] Volcanoes, movement of the tectonic plates, human activity such as bombs
6. What is an earthquake storm?
[ ] A tsunami
[ ] A series of large earthquakes occurring along the same plate boundary
[ ] The raining of molten lava brought up to the Earth’s surface
[ ] A dark cloud of ash that spreads after a large quake
7. What is a tsunami?
[ ] A volcanic eruption on the ocean's floor
[ ] The point at which the ocean reaches the shoreline
[ ] Turbulent waves caused by a hurricane
[ ] A chain of fast moving waves in the ocean caused by powerful earthquakes
8. Earthquakes are this kind of occurrence.
[ ] Frequent
[ ] Geological
[ ] Atmospheric
[ ] Supernatural
9. Which U.S. state experiences the most earthquakes?
[ ] Hawaii
[ ] California
[ ] Alaska
[ ] Washington
10. What is the 'magnitude' of an earthquake?
[ ] The amount of energy that is released by a quake
[ ] The duration of a quake
[ ] The length of a quake
[ ] The destruction caused by a quake
Science: Middle School: Grades 6, 7 and 8 Quiz - Earthquakes (Answers)
1. Earthquakes cause a series of waves called?
[x] Seismic waves
[ ] Tsunamis
[ ] Tidal waves
[ ] Electro-magnetic pulses
We are not looking at water here but rather thinking about vibration and distance
2. What is the Epicenter?
[ ] Where two plates collide
[ ] The measurement of a fault line
[x] The closest location to the center of an earthquake
[ ] A tourist attraction at Disney World
This is being in the very middle of an action
3. What instrument is used to measure the size and duration of an earthquake?
[ ] Magnitude Scale
[ ] Mercalli Scale
[ ] Telescope
[x] Richter Scale
This was developed in 1935. It was intended to be used only in a particular study area in California and on seismograms recorded on a particular instrument, the Wood-Anderson torsion seismograph
4. What is a fault?
[x] A break in the rocks that make up the Earth’s crust
[ ] Where two plates come together
[ ] Where seismic activity is recorded
[ ] A bulge in the Earth's surface
If you take a sledge hammer to a rock, it will do this
5. What are three main causes of earthquakes?
[ ] Volcanoes, movement of the tectonic plates, tsunamis
[ ] Volcanoes, the moon’s gravitational forces, tectonic plate movement
[ ] Volcanoes, the sun’s gravitational forces, tectonic plate movement
[x] Volcanoes, movement of the tectonic plates, human activity such as bombs
Think of ground movements that would be violent enough to cause a change
6. What is an earthquake storm?
[ ] A tsunami
[x] A series of large earthquakes occurring along the same plate boundary
[ ] The raining of molten lava brought up to the Earth’s surface
[ ] A dark cloud of ash that spreads after a large quake
A storm is something that lasts over a period of time and can have a ripple effect
7. What is a tsunami?
[ ] A volcanic eruption on the ocean's floor
[ ] The point at which the ocean reaches the shoreline
[ ] Turbulent waves caused by a hurricane
[x] A chain of fast moving waves in the ocean caused by powerful earthquakes
Rapidly moving waves powerful enough to wash away entire cities
8. Earthquakes are this kind of occurrence.
[ ] Frequent
[x] Geological
[ ] Atmospheric
[ ] Supernatural
Knowing about the study of solid and liquid matter that makes up the Earth will make the answer easy
9. Which U.S. state experiences the most earthquakes?
[ ] Hawaii
[ ] California
[x] Alaska
[ ] Washington
If you know which state is the largest, that is where you’ll find the answer
10. What is the 'magnitude' of an earthquake?
[x] The amount of energy that is released by a quake
[ ] The duration of a quake
[ ] The length of a quake
[ ] The destruction caused by a quake
This would be related to the power and greatness in size
