What is a blank is a break or cracks in the rock of the lithosphere along which movements take place?
What is a Fault?
what is an instrument that detects, measures, and records the energy of earthquake vibrations at a given location?
What is seismograph?
this fault is produced at a transform boundary. the plates slide past each other without moving up or down slabs of rock move past each other in different directions. the Sans Andres fault is an example of this fault. what is this fault called?
what are Strike-slip faults?
What are the fastest seismic waves?
What are P waves?
this question is 2 parts. once magma reaches the surface, it is called lava, after eruptions, lava cools and hardens, forming a mound. After many eruptions, this mound can grow, what is the space around the vent at the top of a volcano called? sometimes a volcano's crater collapses into the vent this forms a very wide crater. What is that crater called?
What is crater for the first one?
What is caldera for the second one?
What is the point below the surface of the earth where an earthquake begins?
What is the focus?
What is the height of a wave on a seismograph that measures the energy released during an earthquake?
What is the magnitude?
This fault is produced at a convergent boundary.
The plates push together. The rock above the fault surface moves upward. The Himalayas in central Asia were formed at this fault. What type of fault is this?
what is a reverse fault?
What are very slow waves and only travel through solids?
What are S waves?
This is a 2 part question. what is a string of volcanoes called?
where plates move apart, volcanoes can form at gaps along the plates' edges. What are these volcanic landforms called?
What is an island arc for question 1?
what is rift volcanoes for question 2?
What are smaller earthquakes that can follow a major earthquake?
what is an aftershock?
what is it when magma reaches the surface it erupts through a central opening?
What is a vent?
This type of fault is produced at a divergent boundary. the plates pull apart. the rock above the fault surface moves down. the Sierra Nevada in California were formed at this fault. What is this kind of fault?
What is a normal fault?
What is a volcano mainly made up of small rock particles or cinders?
What are cinder-cone volcanos?
When magma rises, it pushes against rock layers above it. This can form a large shaped dome structure. Weathering and erosion can then strip away the warped layers, exposing the volcanic rock beneath. The black hills in South Dakota are called this. What is this called?
What are dome mountains?
What is a vibration that travels through the earth and s produced by an earthquake or volcanic eruption?
What is a seismic wave?
this is an italicized word
What are plates that slide past each other at transform boundaries and the pieces of rock rub together called?
What is shearing?
What are mountains made up of mostly rock layers folded by being squeezed together?
What is a folded mountain?
What is a volcano that is mainly made up of small rock particles, or cinders? erupting lava shoots into the air, it breaks into small pieces What is a volcano that is made up of many layers of rock? fluid lava flows out in all directions cools and hardens into rock. what is a volcano made up of thick lava flows alternating layers of ash, cinders, and rocks?
What are Cinder-cone, shield, and composite volcanoes?
If magma hardens in vertical cracks across horizontal layers. What forms?
What is a dike?
What is the location on the earth's surface directly above the focus?
What is the epicenter?
At divergent boundaries, plates separate as new crust forms between them. What is this force called?
What is tension?
What are mountains made by huge, tilted blocks of rock separated from the surrounding rock faults?
What are fault-block mountains?
What are the three types of volcanos?
What are cinder cone, shield, and composite volcanos?
when magma hardens between horizontal layers of rock what is formed?
What is a flat sill?
