The liquid that flows out of a volcano is called ________.

geography volcanoes volcanism earthquake and volcanoes development of landforms earthquakes and volcanoes types and features of earthquakes and volcanoes

  1. Lava

  2. Magma

  3. Mantle

  4. None of these

Show answer
Correct Option: A
Explanation:

Lava is the molten rock expelled by a volcano during an eruption. A lava flow is a moving/outpouring of lava, which is created during a non-explosive effusive eruption. When it has stopped moving, lava solidifies to form igneous rock. The term lava flow is commonly shortened to lava. Although lava can be up to 100,000 times more viscous than water, lava can flow great distances before cooling and solidifying because of its thixotropic and shear thinning properties.

Hot molten rock material inside the earth is called _____and after reacting the earth's surface, it is known as ________.

geography volcanoes volcanism earthquake and volcanoes development of landforms earthquakes and volcanoes types and features of earthquakes and volcanoes

  1. Magma, lava

  2. Lava, magma

  3. Crater, magma

  4. Lava, crater

Show answer
Correct Option: A
Explanation:

Magma is an extremely hot liquid and semi-liquid rock located under Earth's surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet's mantle consists of magma. When magma flows or erupts onto Earth's surface, it is called lava.

Choose the odd one out.

geography our changing earth earthquake and volcanoes earthquake earthquakes

  1. Cyclone

  2. Earthquake

  3. Seismograph

  4. Tsunami

Show answer
Correct Option: A
Explanation:
In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure
While seismograph is an instrument used to detect and record earthquakes. A tsunami is an earthquake in oceans.

The severity of Earthquake is measured on ________________.

  1. richter scale

  2. rain gauze

  3. thermometer

  4. None of these

Show answer
Correct Option: A
Explanation:

The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.

Volcanic activities and seismic occurrences are __________.

geography our changing earth earthquake and volcanoes earthquake earthquakes

  1. Interrelated

  2. Different

  3. Same

  4. None of these

Show answer
Correct Option: A
Explanation:
  • Volcanic activities refer to pouring out of hot magma from weak layers of the earth's crust while seismic occurrences are the shaking of the earth's crust due to the release of energy at plate boundaries. Both the phenomenon occur at the plate boundaries of the earth crust, and they draw energy from the same sources. Thus both are interrelated.

An earthquake is a defined as a tremor below the surface of the earth which causes ______________.

geography our changing earth earthquake and volcanoes earthquake earthquakes

  1. shaking of the crust

  2. shaking of the sea

  3. shaking of the mountain

  4. none of these

Show answer
Correct Option: A
Explanation:

An earthquake is a moment of tremor of the earth's crust. It originates naturally and below the surface. It sometimes causes a permanent change of level at the surface of the earth.
