boundary is it?
Converging
Diverging
Transform
Sea Floor Spreading
Which type of plate boundary would cause mountains to form?
Transform
Convergent
Divergent
Reform
Rocky or rigid outer part of Earth consisting of the brittle crust and the top part of the upper mantle
Lithosphere
Oceanic Crust
Continental Crust
Asthenosphere
Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
Lithosphere
Earthquake
Convection Currents
Core
Solid, outer layer and is made of both the oceanic and continental crust.
Hydrosphere
Core
Mantle
Crust
Hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
Convection Current
Lithosphere
Core
Magma
The thick part of the earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.
Oceanic Crust
Continental Crust
Magma
Inner Core
Which of these tectonic plate boundaries is most likely to form a volcano.
a continental plate colliding with a continental plate
an oceanic plate sliding past a continental plate
a continental plate sliding past a continental plate
an oceanic plate colliding into a continental plate
The huge blocks of the earth's crust that slide around slowly are called
Volcanoes
Tectonic Plates
Rift Valleys
Mid ocean ridges
