Summative Assessment of Explanation Text

Have you ever wondered how volcanoes are formed?

A Volcano is a vent or an opening on the earth’s surface which allows molten rock called magma, volcanic ash and gases to escape out onto its surface.

What is volcano?

• A volcano is a type of cloud formed by condensation of water vapor in the atmosphere
• A volcano is a type of rock found in the ocean
• A volcano is a type of animal that lives in the desert
• A volcano is a vent or an opening on the earth’s surface which allows molten rock called magma, volcanic ash and gases to escape out onto its surface.

What is magma?

• Magma is a type of marine animal found in the ocean.
• Magma is Molten rock.

• Magma is a type of sedimentary rock found in riverbeds.
• Magma is a type of cloud formation in the atmosphere.

Volcanoes are formed whenever there is a crack in the crust of the earth. A tube-like passage connects a chamber of magma (molten rock) at the center of the earth to the earth’s crust. When the pressure builds up in the chamber, the magma, gases and ash are pushed up through to the top of the tube on the earth’s surface known as vent.

How are volcanoes formed?

• Volcanoes are formed by the accumulation of snow and ice
• Volcanoes are formed by the erosion of rocks
• Volcanoes are formed by the movement of tectonic plates
• When there is a crack in the earth's crust, allowing magma, gases, and ash to be pushed up to the surface through a tube-like passage known as a vent.

The red hot magma that escapes to flow over the Earth’s surface is called lava which, when cools, forms into rocks.

What is lava?

• Lava is a type of cloud formation in the atmosphere
• Red hot magma that flows over the Earth’s surface and forms into rocks when it cools.
• Lava is a type of volcanic gas emitted during an eruption
• Lava is a type of underground water source

The red hot magma that escapes to flow over the Earth’s surface is called lava which, when cools, forms into rocks.

How is the form of lava when it cools?

• It transforms into plants
• It becomes a gas
• It turns into water
• It forms into rocks

In fact, the mountains we see today are nothing but solidified lava from previously erupted volcanoes.

What is mountain actually?

• Solidified lava from previously erupted volcanoes
• Result of tectonic plate movement
• Deposits of sedimentary rocks
• Fossilized tree trunks

Choose natural phenomena in the options below?

• Earthquakes, lightning, rainbows
• Traffic jam
• World war

• Fire
