Earthquakes
The tool used to record earthquake waves
a. barometer
b. seismograph
c. thermometer
d. richter scale
What is a seismograph?
Molten rock that has erupted from a volcano and is on Earth's surface
a. Lava
b. Magma
What is lava?
The layer of the Earth that is broken into tectonic plates
What is the crust?
These lines run east-west (horizontal) and help determine a location’s position north or south of the equator.
What is latitude?
The molten rock found beneath Earth’s surface.
What is magma?
The scale used to measure the magnitude (strength) of an earthquake
a. mercalli
b. mohs
c. richter
d. celsius
What is the Richter scale?
A dormant volcano is:
a. currently erupting
b. has never erupted
c. not currently erupting but could erupt again
d. completely extinct and will not erupt again
What is not currently erupting but could erupt again?
The movement of tectonic plates causes this
What are earthquakes, volcanoes, and mountain formation?
These lines run north-south (vertical) and help determine a location’s position east or west of the prime meridian.
What is longitude?
These types of natural disasters are especially common in the Ring of Fire.
What are earthquakes and volcanoes?
The point on Earth's surface directly above the Earthquake's focus, marking the Earthquake's origin
What is the epicenter?
The name of a volcano that is large and broad with gentle slopes
The type of stress caused when forces push two rocks together
What is compression?
On a map, most earthquakes and volcanoes are found along this kind of edge.
What is a plate boundary?
The Ring of Fire stretches around this ocean basin.
What is the Pacific Ocean?
The point inside the Earth, in the crust, where an earthquake begins
What is the focus?
The type of stress caused when rocks are pulled apart (like a rubber band)
What is tension?
When mapping, this term describes the area where the most earthquakes and volcanoes occur together.
What is a hot spot?
This U.S. state is famous for both volcanoes and earthquakes.
What is Alaska/California/Hawaii?
The seismic wave that travels the fastest and can travel through both solids and liquids
What are P (primary) waves?
A small, steep volcano built from ash and cinders, with violent eruptions
What is a cinder cone volcano?
What is a strike-slip fault?
The process of finding an earthquake’s epicenter by using data from three stations.
What is triangulation?
This South American mountain range is part of the Ring of Fire.
What are the Andes Mountains?
