What is the process that continually adds new crust to the ocean floor along mid-ocean ridges?
molten material
plate tectonic
sea floor spreading
deep ocean trench
When continental plates pull apart a (a) boundary on land, plates form.
If subduction occurs faster than oceanic crust can be created, an ocean will expand.
True
False. It can renew
Oceanic crust near the mid-ocean ridge is younger than oceanic crust farther away from the ridge.
True
False. It is older
Mid ocean ridges form the longest mpountain ranges on Earth.
True
False. They form the highest, not the longest
A long divergent boundary plate slips past each other , moving in opposite direction.
True
False. It is transform boundary
Tension is the stress force that pulls on the crust and thin rock.
True
False
A dormant volcano is erupting or may erupt in the near future
True
False. It is an active volcano
A pyroclastic flow typically occurs during a quiet eruption.
True
False. It is explosive
A major volcano belt located throughout the Pacific Ocean is best known as (a)
The bowl-shaped area around a volcano's central vent is called a (a)
A mass of rock that forms when a large body of magma cools inside the crust is called a (a)
Magma forces the rock to bend upward into a landform called a (a)
A (a) forms when magma forces itself .
(a) is the molten material before lava reaches the surface.
(a) is the huge hole left by the collapse of a volcanic mountain.
(a) is when many layers of thin, runny lava build up
