What is the source of materials for volcanoes that erupt in both ways?

What is the source of materials for volcanoes that erupt in both ways?

What is the source of materials for volcanoes that erupt in both ways How do you know? The crust must have continental (granitic) plate and oceanic (basaltic) plate to cause both explosive (granitic magma) and non-explosive (basaltic magma) eruptions.

What is the source of a volcanic eruption?

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth’s mantle melts. Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Magma is lighter than rock so rises towards the Earth’s surface.

What are the materials of a volcano?

Let’s build a volcano!

• Aluminum cookie sheet.
• Cardboard box.
• Lots of old newspaper.
• Measuring spoon and measuring cup.
• Modeling clay (flour, salt, water)
• Funnel.
• Small plastic bottle (like a small pop bottle)
• Baking soda (about 3-4 tablespoons)

Which of the following structure is made up by the deposition of volcanic materials answer?

Answer: The peninsular plateau or Deccan plateau.

Which of the following structure is made up by the deposition of volcanic materials?

Types of Volcanic Cones. A volcanic cone is the triangle-shaped hill formed as material from volcanic eruptions piles up around the volcanic vent, or opening in the Earth’s crust.

How do volcanoes form and erupt?

On land, volcanoes form when one tectonic plate moves under another. Usually a thin, heavy oceanic plate subducts, or moves under, a thicker continental plate. When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.

How do you make a volcano erupt?

Step 1: First, place an empty plastic bottle in a mound of sand. Step 2: Use a funnel to add some baking soda to the bottle. Step 3: Mix some food coloring and vinegar together and pour this mixture inside the bottle and watch your volcano erupt!

Which of the following volcanic eruption is composed of gas and pyroclastic material?

Strombolian eruption
This type of eruption is called a Strombolian eruption, and is considered mildly explosive. If the eruption column collapses a pyroclastic flow will occur, wherein gas and tephra rush down the flanks of the volcano at high speed.

How is a volcano made?

Volcanoes are vents, or openings in Earth’s crust, that release ash, gases and steam, and hot liquid rock called lava. When the lava cools and hardens, it forms into the cone-shaped mountain we think of as a volcano. On land, volcanoes form when one tectonic plate moves under another.

What kind of materials are produced by a volcanic eruption?

11.2 Materials Produced by Volcanic Eruptions. Volcanic eruptions produce three types of materials: gas, lava, and fragmented debris called tephra.

Where does the magma come from to cause a volcano to erupt?

Volcanoes erupt when magma, red-hot liquid rock, seeps up through a vent in the earth. These vents can be at the top of a mountain or on a flat area. Volcanoes can even erupt underwater if there is a vent in the ocean floor.

What kind of gases come out of a volcano?

The most common volcanic gas is water vapor, followed by carbon dioxide and sulfur dioxide. Sulfur dioxide can cause breathing problems in both healthy people and people with asthma and other respiratory problems.

Why are some volcanoes more explosive than others?

Some volcanic eruptions are explosive and others are not. The explosivity of an eruption depends on the composition of the magma. If magma is thin and runny, gases can escape easily from it. When this type of magma erupts, it flows out of the volcano.
