SECTION: HOW ROCK DEFORMS
Oregon, and northern California
They are part of mid-ocean ridges
along divergent plate boundaries.
Magma rising to Earth’s surface at
divergent boundaries makes midocean ridges volcanically active.
when the peaks of volcanic mountains
rise above sea level; the Azores in the
North Atlantic
on the ocean floor at hot spots
Hot spots are volcanically active
areas that lie far from tectonic plate
boundaries. Hot material rises through
Earth’s interior and reaches the lithosphere.
