Earth's Spheres
The air that surrounds the Earth. (Atmosphere or Geosphere)
Atmosphere
The innermost layer or center of the Earth. (crust or core)
core
A large super continent. A Greek word meaning "all earth". (Pacific or Pangaea)
Pangaea
The edge of a tectonic plate where it meets other plates. (rim or boundary)
boundary
A volcano that has recently erupted or is likely to erupt. (active or dormant)
active
All the Earth’s salt water and freshwater. (Geosphere or Hydrosphere)
Hydrosphere
The layer of iron-rich minerals surrounding the core. (crust or mantle)
mantle
A large section of the earth’s crust: _________ plates
tectonic plates
A boundary formed between two plates that move apart. (divergent boundary or convergent boundary)
divergent boundary
The shaking of rock in the earth’s crust. (volcano or earthquake)
earthquake
The part of the Earth that holds all living things. (Geosphere or Biosphere)
Biosphere
The outermost layer or surface of the Earth. (crust or core)
crust
The thin section of the earth’s crust below the ocean. (continental crust or oceanic crust)
oceanic crust
A boundary formed between two plates that collide. divergent boundary or convergent boundary
convergent boundary
A cone shaped mountain that forms around a vent where magma is forced to the surface. (earthquake or volcano)
volcano
The Earth’s crust and its inner layers. (Biosphere or Geosphere)
Geosphere
Minerals in the form of hot liquid rock found in the mantle. (Magma or Lava)
Magma
The thick section of the earth’s crust below the continents. (continental crust or oceanic crust)
continental crust
A boundary formed when 2 tectonic plates slide past one another in opposite directions. (convergent boundary or transform boundary)
transform boundary
A scale used to measure an earthquake’s strength. (Hint: starts with an "R")
Richter Scale
Name something that would be part of the Earth's biosphere (something living).
any time of plant, tree, flower, or animal
Why/how is an avocado similar to the Earth's Layers? (which part is like the crust, mantle, and core)
It has a core and the outside peel is like the crust. The part you eat is like the mantle.
Alfred Wegener’s theory that the earth’s crust is divided into sections or plates that move.
Continental Drift Theory
The heating and cooling of magma in the mantle. (convection current or convergent current)
convection current
A large, forceful wave triggered by ocean floor earthquakes. (starts with "Ts")
Tsunami
