island arcs
10
Where is an ocean trench likely to occur?
a subduction zone
on the east coast of a continent
a divergent boundary
a transform boundary

How does Earth's lithosphere differ from its asthenosphere?
The lithosphere is cooler and more brittle
The lithosphere is hotter and more brittle
The lithosphere is cooler and more fluid-like
