Section 5.1 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 ______.

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 boundariesof Earth’s plates. Volcanoes can be found at divergentboundaries, 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 anisland 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.
