  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.

  1. Crust

  2. Earth

  3. Surface

  4. Focus

Show answer
Correct Option: D
Explanation:

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

An earthquake's point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypocenter.

Sometimes hot molten rocks formed inside the earth are forced out through openings in the earth's surface such as the craters in volcanoes. What is the molten rock inside the earth called?
