Which features do most stratovolcanoes and cinder cone volcanoes have in common?
violent eruptions and thin, flowing lava
broad base with quiet eruptions
steep sides and violent eruptions
wide dome shape and thick lava
Which statement identifies a major reason for the subduction that helps to form volcanoes?
the unusually high temperature at hotspots
the release of hot ash and steam in a pyroclastic flow
the difference in density of oceanic and continental plates
the upwelling of magma between diverging plates
Why is no land created or destroyed at transform boundaries?
because magma rushes into gaps at these boundaries
because the plates crumble into each other at these boundaries
because the plates are more dense at these boundaries
because the plates only slip past each other at these boundaries
Geologists observed signs of widespread ancient glaciers from the same time period in areas across South America, Africa, Antarctica, India, and Australia. What theory did this observation support?
Earth was much farther than the sun than it is today.
Most of Earth was once covered in a vast ice sheet.
Those continents were once together as one supercontinent.
Glaciers were once more common than they are today.
Along which features does seafloor spreading occur?
fault lines
mid-ocean ridges
ocean trenches
ocean basins
Ocean trenches form over millions or billions of years. Which statement accurately describes how ocean trenches form?
a plate of continental crust collides with another plate of continental crust
two plates of continental crust slide past each other
a plate of oceanic crust is subducted under a plate of continental crust
two plates of oceanic crust pull away from each other
