A U-shaped Valley is formed by a-
River
Wind
Glacier
Rainfall
Waves erode and change the shape of -
Coastlines
Canyon walls
Crater rims
Deltas
Transfer of thermal energy caused by the rising of hotter less dense fluids and the sinking of cooler more dense fluids:
convection
conduction
radiation
density
What does the theory of Continental Drift explain?
Ocean currents move continents around the planet
Convection works deep within the asthenosphere
Mid-ocean ridges force tectonic plates to move
Continents were once together and slowly drifted to where they are today
Where does seafloor spreading take place?
Convergent boundaries
The continentals shelves
Transform boundary
Mid-ocean ridges
What layer of the Earth do convection currents occur in?
Crust
Lithosphere
Asthenosphere
If you took rock samples from the Mid-Atlantic Ridge, the youngest rock would be
located where the plates collide
located at the place where rocks are furthest from the rift valley
Located at the center of the ridge (rift valley), where oceanic crust is formed
none of the above; all the rocks would be the same age
What do these color strips show between South America and Africa with the Theory of Continental Drift?
Similar cultures
Similar fossils
Similar languages
Similar weather
