Volcanoes
Liquid magma that flows from a volcano (outisde of Earths crust)
Lava
Earth's outermost, rigid, rocky layer is called what?
the crust
The theory that the continents are slowly moving away from each other.
Continental Drift.
What is a crack in earths surface called
Fault
The study of Earthquakes.
Seismology
Which plate boundary where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction
convergent plate boundary
What is the mantle made of?
Molten rock
What type of boundary are the plates moving away from each other?
Divergent Boundary
Which core is solid and which is liquid?
outer cores is liquid
inner core is solid
What type of boundary would most likely cause an earthquake to occur?
Transform
Volcanoes that have erupted recently are called what?
Active volcanoes
which crust lies beneath the ocean?
oceanic crust
Convergent boundaries are most likely to create what landform?
Mountains
Volcanos
the place inside Earth's crust where an earthquake originates
Focus
What type of waves only travel through solids
S waves
This refers to a group of volcanoes along the pacific plate.
Ring of Fire
what are the two different types of crust?
oceanic and continental crust
What does the plate movement look like at a transform boundary.
Sliding, scraping, or slipping past each other.
What is the "supercontinent" when all the land formed one landmass called?
Pangea
Siesmologists would most likely use a what instrument to study the waves of an earthquake?
Seismograph
mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks
convection currents
List the Earths Layers from most thick to least thick.
Mantle
Outer Core
Inner Core
Crust
Gigantic pieces of the Earth's crust and uppermost mantle
tectonic plates
the point on the earth's surface vertically above the focus of an earthquake.
Epicenter
What type of wave can travel through solids and liquids
P Waves
