Earths Interior
About 3 to 5 miles thick, this layer of the Earth is mostly made of basaltic rock.
What is the Oceanic Crust?
The largest of all the tectonic plates, this plate stretches from the west coast of North America to the east coast of Japan and Indonesia.
What is the Pacific Plate?
Occurring when two plate tectonics move away from each other, this type of plate boundary is called a this
What is a Divergent Boundary?
This “hot” area lies in the middle of a tectonic plate, and volcanoes form in this space when magma from the mantle melts through the crust.
What is a Hot Spot?
Erupting in 79 A.D. this volcano destroyed the ancient Italian city of Pompeii.
What was Mount Vesuvius?
Also known as the Plastic Mantle, this layer of the Earth has a similar consistency to asphalt.
What is the Asthenosphere?
Underlying both a continent and part of the Atlantic ocean, this tectonic plate is nearly 76,000,000 square kilometers.
What is the North American Plate?
Moving through both solids and liquids, these types of earthquake waves bend and change direction when they hit layers of different densities.
What are Primary Waves?
After numerous eruptions build up layers, these steep sided, tall, and picturesque volcanoes form.
What is a Composite Volcano?
Categorized as one of "The Seven Summits," this volcano has an elevation of 5895 meters
What is Mount Kilimanjaro?
The crust and the upper rigid mantle together make up this layer of the Earth.
What is the lithosphere?
Consisting of Europe, Russia, and parts of Russia, this tectonic plate shifts about half of an inch a year.
What is the Eurasian Plate?
Spanning over 800 miles, the San Andreas Fault, located in California, was a result of this type of plate boundary.
What is a Transform Boundary?
Usually less than 1000 meters tall, these cone shaped volcanoes have explosive eruptions.
What is a Cinder Cone Volcano?
Located in Washington, this volcano erupted in 1980, killing 57 people, including former president Harry Truman
What was Mount Saint Helens?
Made up of the melted metals Nickel and Iron, this liquid layer of the Earth causes the Magnetosphere.
What is the Outer Core?
While many consider this plate to be two separate plates, this tectonic plate stretches from India to Australia
What is the Indo-Australian Plate?
Moving only through solids, this type of Earthquake wave is called a this.
What are Secondary Waves?
Broad, large, and dome shaped, these volcanoes are Built up from flows of very hot and runny lava that can travel great distances before cooling.
What are Shield Volcanoes?
With its Last eruption in 1707, this Japanese volcano is still active, and has a height of 3776 meters
What is Mount Fuji?
Scientists have figured out the internal structure of the Earth by studying this natural disaster.
What is an Earthquake?
With an area of nearly 70 million Kilometers Squared, this plate touches the African, Australian, Pacific, and South American plates.
What is the Antartic Plate?
Causing several Earthquakes, these types of plate boundaries are also known as destructive boundaries
What are Convergent boundaries?
Volcanoes that form on these plate boundaries become volcanic islands and mountain ranges.
What are convergent Boundaries?
Located in Hawaii, this volcano last erupted in 1984, and is famous for being the largest active volcano on the planet
What is Mount Muana Loa?
