Earth's Layers
What is crust, mantle, outer core, inner core?
The three types of plate boundaries, AND how they move.
What is convergent (plates collide), divergent (plates move apart), and transform (plates slide past one another) boundaries?
The difference between magma and lava.
What is magma is found inside the earth's crust and lava is found outside the earth's crust?
The tool that measures seismic waves.
What is a seismograph?
Two differences between continental crust and oceanic crust.
What is the continental crust is granite rock, older, thicker, and less dense; the oceanic crust is basalt rock, younger, thinner, and more dense?
This layer is made up of LIQUID nickel and iron.
What is the outer core?
Which of the following does NOT occur at a convergent boundary?
a. Mountain Ranges
b. Earthquakes
c. Volcanoes Form
d. Mid ocean ridge
What is d. mid ocean ridge?
The 3 classes of volcanoes.
What is active, dormant, and extinct?
What is a fault?
The asthenosphere is found in this layer.
What is the mantle?
This layer is made of hot dense rock and is the thickest layer.
What is the mantle?
The process where one lithospheric plate collides with another lithospheric plate and the more dense plate moves under the less dense one and sinks into the mantle; occurs at convergent boundaries.
What is subduction?
A volcanically active place that is far away from a plate boundary.
What is a hot spot?
List the 3 types of waves in order from fastest to slowest.
What is primary, secondary, and surface waves?
Name two places that earthquakes occur.
What is along plate boundaries, in volcanic regions, and along fault zones?
These two layers make up the lithosphere.
What is the crust and mantle?
The process of magma from the mantle being pushed upward to the surface of the Earth and spreading apart, creating new Earth, occurs at divergent boundaries.
What is seafloor spreading?
This plate boundary does not have volcanoes.
What is transform boundary?
An earthquake is caused by sudden shifts in which layer of the earth. a. outer core
b. mesosphere c. crust
What is c. crust?
The most destructive type of seismic wave
What is surface wave?
This layer is made of solid nickel and iron and can be as hot as the surface of the sun.
What is the inner core?
Alfred Wegener's belief that all of the continents were once connected into one supercontinent
What is continental drift?
The majority of volcanoes occur in this area around the Pacific Plate as a result of subduction of oceanic plates underneath lighter continental plates.
What is Ring of Fire?
Compare the location of plate boundaries to the location of earthquakes and volcanoes.
What is earthquakes and volcanoes are most likely to occur on plate boundaries due to the movement of the plates in this area?
