What is convection correct answersCold air sinks because it is more dense
What is the lithosphere correct answersThe top part of the mantle and all crust, on top of
asthenosphere
In SoCal our plate boundary is... (list plate, boundary and rise) correct answersPacific plate,
transform boundary, east pacific rise
Why is San Francisco in the same location correct answersIt must be East of the San Andreas
What will happen to Western California correct answersIt will move more northwest
Where on Earth can you stand above sea level on a Mid-Ocean Ridge? correct answersIceland
Geographic example of oceanic-continental convergent with subduction zone? correct
answersThe cascades

What type of crust is thicker? continental or oceanic correct answersContinental
What type of crust is denser? continental or oceanic correct answersOceanic
Why does oceanic lithosphere at ridges rise higher than at trenches? correct answersbecause it is
less dense (trenches are deep and have more water)
