CLOZE ACTIVITY
A weak spot in the crust where molten material, or magma comes
to the surface is called a ___________. Remember that magma is a
molten mixture of rock-forming substances, _____________, and
water from the mantle. When magma reaches the ____________ it
is called lava.
A major volcanic belt formed by the many volcanoes that rim the
Pacific Ocean is called ______________________. Volcanic belts
form along ________________ of Earth’s plates. Volcanoes can be
found at _______________ boundaries, where plates pull apart.
These volcanoes can be found along the Mid Ocean Ridge beneath
the ocean. Volcanoes can also form near _______________
boundaries, where two plates collide. Volcanoes that form along
converging boundaries beneath the ocean can build land forms.
Volcanoes that break through the top of the ocean water can create
a string of islands called an _______ _________. Examples of major
island arcs include ____________, ___________________,
_____________, _______________, _______________, and
________________________.
A _________ __________ is an area where material from deep
within the mantle rises and then melts, forming magma. A volcano
forms above a hot spot when magma erupts through the
____________ and reaches the surface. An example of a state
formed by a hot spot volcano is _____________.

CLOZE ACTIVITY
A weak spot in the crust where molten material, or magma comes to
the surface is called a Volcano. Remember that magma is a molten
mixture of rock-forming substances, gases, and water from the
mantle. When magma reaches the surface it is called lava.
A major volcanic belt formed by the many volcanoes that rim the
Pacific Ocean is called The Ring of Fire. Volcanic belts form along
boundaries of Earth’s plates. Volcanoes can be found at divergent
boundaries, where plates pull apart. These volcanoes can be found
along the Mid Ocean Ridge beneath the ocean. Volcanoes can also
form near converging boundaries, where two plates collide.
Volcanoes that form along converging boundaries beneath the ocean
can build land forms. Volcanoes that break through the top of the
ocean water can create a string of islands called an island arc.
Examples of major island arcs include Japan, New Zealand,
Indonesia, the Philippines, the Aleutians, and the Caribbean islands.
A hot spot is an area where material from deep within the mantle
rises and then melts, forming magma. A volcano forms above a hot
spot when magma erupts through the crust and reaches the surface.
An example of a state formed by a hot spot volcano is Hawaii.
