Earthquakes
Part 1
Part 1
The vibration caused by the rupture and sudden movement of rocks along a break or a crack in Earth’s crust is a(n) what?
What is an earthquake?
A plate boundary involves more than one of these.
What are faults?
Geologists call molten rock stored beneath Earth’s surface this.
What is magma?
Volcanoes erupt in these two ways.
What is as a lava flow or explosion?
At these two types of plate boundaries, lava hardens and forms new crust.
What are convergent and divergent plate boundaries?
An earthquakes can occur here, which is a crack or a fracture in Earth’s crust along which movement occurs.
What is a fault?
The movement of crust along faults can make these three things.
What are mountains, valleys and other land formations?
Molten rock beneath the earth's surface that erupts onto Earth’s surface is called this.
What is lava?
In this type of volcanic eruption, molten rock can flow over Earth’s surface before cooling, hardening, and becoming solid rock.
What is a lava flow?
Long, narrow mountains formed by magma at divergent boundaries are called these.
What are mid-ocean ridges?
Earthquakes occur because of these that are occurring beneath the tectonic plates, causing forces to build up along faults at plate boundaries.
What are convection currents?
Mid-ocean ridges form at these types of boundaries between oceanic plates.
What are divergent boundaries?
These are vents in Earth’s crust through which molten rock flows.
What are volcanos?
Mount St. Helens in 1980 is an example of this type of volcanic eruption.
What is an explosive eruption?
These form near plate boundaries because folding and crumpling usually occur at the edges of plates.
What are most mountains?
The size of an earthquake is called this and is determined by how much energy is released during the earthquake.
What is its magnitude?
At this type of plate boundary with a subduction zone, the plate that does not subduct deforms and crumples as the two plates push toward each other.
What is a convergent plate boundary?
Most volcanoes form at these type of plate boundaries.
What are convergent plate boundaries?
Tiny pieces of glass made from solidified lava that can be blown high into the atmosphere is called this.
What is ash?
Large mountain ranges form when two continents collide where?
Where is at a convergent plate boundary?
The strongest, most damaging earthquakes occur where two plates move in this way.
What is when one plate subducts another plate?
At this type of plate boundary without a subduction zone, the edges of both tectonic plates become crumpled and deformed.
What is a convergent plate boundary?
Magma formed from the subducted plate then rises toward the surface and forms volcanoes here.
What is on the plate that does not subduct?
A line of volcanoes forms parallel to the plate boundary directly above the plate that subducted is called this.
What is a volcano arc?
This famous mountain range is the world’s largest and highest mountain range, and they are
still growing.
What are the Himalayan Mountains?
