    The huge hole left by the collapse of a volcanic mountain is called a  

    • Lava plateau

    • Caldera

    • Cinder cone

    • Shield volcano

    Correct Answer
    A. Caldera
    Explanation
    A caldera is a large depression or crater that forms when a volcanic mountain collapses or explodes during a volcanic eruption. The collapse occurs when the magma chamber beneath the volcano empties, causing the overlying structure to lose support and collapse into the void. Calderas can be several kilometers in diameter and can be filled with water or become the site of new volcanic activity. This term accurately describes the huge hole left by the collapse of a volcanic mountain.

    Alternating layers of lava and ash form a type of volcanic landform called a(n) ____________________ volcano.  

    Correct Answer
    composite
    Explanation
    Alternating layers of lava and ash create a volcanic landform known as a composite volcano. Composite volcanoes, also called stratovolcanoes, are characterized by their steep slopes and symmetrical shape. They are formed by the eruption of viscous lava, which tends to build up and solidify, creating layers of hardened lava and ash. These volcanoes are typically explosive and can have a variety of eruptive styles, including both effusive and explosive eruptions.

    A large mass of rock that forms from cooled magma inside the crust is called a(n) ____________________.  

    Correct Answer
    batholith
    Explanation
    A batholith is a large mass of rock that forms from cooled magma inside the crust. It is formed when magma rises towards the surface but cools and solidifies before it reaches the surface. Batholiths are typically composed of granite or other coarse-grained igneous rocks. They are often found in mountainous regions and can cover vast areas. Batholiths are important in geology as they provide insights into the processes of magma intrusion and the formation of mountain ranges.

    A huge hole, or ____________________, is left when the roof of a volcanic mountain’s magma chamber collapses.  

    Correct Answer
    caldera
    Explanation
    A huge hole, or caldera, is left when the roof of a volcanic mountain's magma chamber collapses. This occurs when the pressure from the magma chamber becomes too great and causes the overlying rock to fracture and collapse. The collapse creates a large, circular depression on the surface, often filled with water or subsequent volcanic activity. Calderas can vary in size and depth, and are typically formed after a volcanic eruption or series of eruptions. They are a significant feature of volcanic landscapes and can be found in various locations around the world.

    The bowl-shaped area around a volcano’s central vent is called a(n) ____________________.  

    Correct Answer
    crater
    Explanation
    A volcano's central vent releases lava and other volcanic materials during an eruption. The bowl-shaped area that forms around this vent is called a crater. It is created by the explosion or collapse of the volcano's summit during an eruption. The crater is often the most recognizable feature of a volcano and can vary in size and shape depending on the eruption.

    A mass of rock formed when a large body of magma cools inside the crust is called a  

    • Neck

    • Dike

    • Lava plateau

    • Batholith

    Correct Answer
    A. Batholith
    Explanation
    A batholith is a mass of rock that forms when a large body of magma cools inside the crust. It is characterized by its large size and deep-seated nature. Batholiths are typically composed of various types of intrusive igneous rocks and can cover extensive areas underground. They are often associated with mountain building processes and can be exposed at the surface through erosion over time.

    Hardened magma in a volcano’s pipe that remains when softer rock around it has worn away is called a(n) ____________________.  

    Correct Answer
    volcanic neck
    Explanation
    A volcanic neck is formed when hardened magma in a volcano's pipe remains after the surrounding softer rock has eroded away. This creates a vertical column of solidified magma that extends from the underlying magma chamber to the surface. The volcanic neck is often characterized by its distinct shape and can be exposed through erosion or uplift of the surrounding landscape.

    Tall, cone-shaped mountains in which layers of lava alternate with layers of ash are called  

    • Shield volcanoes

    • Cinder cone volcanoes

    • Composite volcanoes

    • Lava plateaus

    Correct Answer
    A. Composite volcanoes
    Explanation
    Composite volcanoes, also known as stratovolcanoes, are tall, cone-shaped mountains formed by alternating layers of lava and ash. These volcanoes are characterized by explosive eruptions due to the high viscosity of the lava. The lava flows from composite volcanoes are thick and sticky, causing them to cool and harden before flowing far from the vent. This results in the accumulation of layers of lava and ash, giving rise to the characteristic composite structure. Examples of composite volcanoes include Mount Fuji in Japan and Mount St. Helens in the United States.

    When many layers of thin, runny lava build up a high, level area, the result is a  

    • Lava plateau

    • Shield volcano

    • Cinder cone volcano

    • Composite volcano

    Correct Answer
    A. Lava plateau
    Explanation
    A lava plateau is formed when many layers of thin, runny lava accumulate over time, creating a high, level area. This type of volcanic feature is typically characterized by extensive flat or gently sloping surfaces, resulting from the repeated eruptions of low-viscosity lava. The lava spreads out over a large area, covering the landscape and forming a plateau-like structure. Unlike shield volcanoes, which have a broad, gently sloping shape, or cinder cone and composite volcanoes, which are more conical in shape, a lava plateau is characterized by its extensive, flat surface.

    When ash, cinders, and bombs build up in a steep pile around a volcano’s vent, the result is a  

    • Cinder cone volcano

    • Shield volcano

    • Composite volcano

    • Dormant volcano

    Correct Answer
    A. Cinder cone volcano
    Explanation
    When ash, cinders, and bombs build up in a steep pile around a volcano's vent, the result is a cinder cone volcano. This type of volcano is characterized by its steep sides and a symmetrical cone shape. Cinder cone volcanoes are typically smaller in size compared to other types of volcanoes and are formed by explosive eruptions. The accumulation of ash, cinders, and bombs creates the cone shape, and the loose, fragmented material gives the volcano its characteristic appearance. Cinder cone volcanoes are often found in volcanic fields and can be found in various parts of the world.

    When magma hardens in a volcano’s pipe, the result will eventually be a landform called a  

    • Batholith

    • Dike

    • Volcanic neck

    • Sill

    Correct Answer
    A. Volcanic neck
    Explanation
    When magma hardens in a volcano's pipe, it cools and solidifies over time. As the surrounding rock erodes away, the hardened magma is left exposed, forming a landform known as a volcanic neck. This landform is essentially the solidified remains of a volcano's conduit or pipe, which once transported magma from the Earth's interior to the surface. Over time, erosion removes the softer surrounding rock, leaving behind a tall, narrow, and often steep-sided structure that is characteristic of a volcanic neck.

    When magma squeezes between layers of rock ,it forms a

    • Neck

    • Dike

    • Sill

    • Lava plateau

    Correct Answer
    A. Sill
    Explanation
    When magma squeezes between layers of rock, it can form a sill. A sill is a horizontal sheet-like intrusion of magma that solidifies between existing rock layers. This occurs when the magma is injected parallel to the layering of the surrounding rocks. Sills are typically found in areas of volcanic activity and can be seen as horizontal bands of igneous rock cutting across the layers of sedimentary or metamorphic rocks.

    Magma that forces across rock layers hardens into a  

    • Sill

    • Volcanic neck

    • Dike

    • Batholith

    Correct Answer
    A. Dike
    Explanation
    When magma forces its way across rock layers, it can harden into a dike. A dike is a vertical or near-vertical sheet of igneous rock that cuts across existing rock layers. It forms when magma is injected into fractures or cracks in the surrounding rock and solidifies underground. Dikes are typically narrower than sills and can vary in thickness. They are important geological features and can be found in various rock formations around the world.
