Weird Words
All the continents in one single landmass.
Pangaea
The outside layer of Earth… the one you're sitting on.
Crust
Wegener’s (and your) first observation about the shapes of the continents.
They fit like a puzzle.
The proven theory that continents have moved slowly over time.
Continental Drift
The outer layer of Earth…the one you're sitting on.
Crust
The theory that Earth is made of drifting broken pieces of crust Plate __________.
Tectonics
The layer at the very
center of Earth.
Inner Core
These geologic objects, formed by volcanic lava flows, are the same on different continents.
Igneous Rocks
These traveled around Pangaea and their fossil
evidence can be found an ocean apart today.
Animals
The center of the Earth, both inner and outer.
Core
The mechanical layer of Earth that includes the crust and upper mantle.
Lithosphere
The compositional layer between the crust and the core.
Mantle
These large geologic formations start on one continent, but end on another with an ocean in between.
Mountain Ranges
The layer of Earth where molten rock is moving in large convection cells.
Mantle or Asthenosphere
Sedimentary rocks often record this, the average weather conditions.
Climate
The plastic-like layer below the crust where convection currents move horizontally.
Asthenosphere
The mechanical layer of Earth that includes the crust and upper mantle.
Lithosphere
The average weather conditions recorded in sedimentary rocks like coal and sandstone.
Climate
In a fluid, it’s the cycle of cooling and sinking and
warming and rising caused by changes in density.
Convection Currents
The constant cycle of rising and sinking in a fluid, a double “C.”
Convection Currents
The scientist who proposed the theory of Continental Drift and Pangaea.
Must be pronounced correctly.
Wegener
The plastic-like layer below the crust where convection currents move horizontally.
Asthenosphere
Scratches on rocks that formed in very cold places, now found in warm places.
Glaciation
The universal force that causes colder, denser material to sink in a fluid.
Gravity
Ancient tropical swampy forests turned into this,
and are now found in cold places.
Coal
