What is ERUP?

1 : to send out lava, rocks, and ash in a sudden explosion The volcano erupted. 2 : to burst out in a sudden explosion Lava erupted from the volcano. 3 : to happen, begin, or appear suddenly War erupted.

What is volcanic eruption Definition?

A volcanic eruption is when lava and gas are released from a volcano—sometimes explosively. The most dangerous type of eruption is called a ‘glowing avalanche’ which is when freshly erupted magma flows down the sides of a volcano.

What does E mean in erupt?

Origin of erupt

First recorded in 1650–60; from Latin ēruptus “burst forth, broken out” (past participle of ērumpere ), equivalent to ē- “out of, from” + ruptus, past participle of rumpere “to break, rupture”; see origin at e-¹, rupture.

What happens when a volcano erupts?

When volcanoes erupt they can spew hot, dangerous gases, ash, lava and rock that can cause disastrous loss of life and property, especially in heavily populated areas. Volcanic activities and wildfires affected 6.2 million people and caused nearly 2400 deaths between 1998-2017.

How volcanoes are formed?

A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.

What is a volcanic eruption called?

There are two types of eruptions in terms of activity, explosive eruptions and effusive eruptions. Explosive eruptions are characterized by gas-driven explosions that propels magma and tephra. Effusive eruptions, meanwhile, are characterized by the outpouring of lava without significant explosive eruption.

What is a volcano Kid definition?

A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.

How do you describe a volcano?

A volcano is defined as an opening in the Earth’s crust through which lava, ash, and gases erupt. The term also includes the cone-shaped landform built by repeated eruptions over time.

What are volcanoes Class 7?

A volcano is a vent from which a combination of melted rock, solid rock debris and gas erupts. It has a reservoir of molten material below the surface (magma chamber) called magma, and when this magma rises to the surface, it is called lava.

What’s in a volcano?

Volcanoes are openings, or vents where lava, tephra (small rocks), and steam erupt on to the Earth’s surface.

Why does a volcano occur?

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 is a volcano give one example?

Answer. A volcano is a vent in the earth’s crust from which fiery hot magma erupts from the earth’s interior. For example, Mt. Stromboli in Italy.

How much lava is in a volcano?

Using the preliminary map, we can calculate a rough estimate of the total volume of lava erupted and added to the land surface—about 0.8 cubic kilometers (over a million cubic yards).

What is cold lava?

Cold lava flows, also known as lahars, are mud flows consisting of volcanic ash, rocks and other debris. The flows can travel quickly and effectively bulldoze or bury anything in their paths.

Why is lava so hot?

Lava is hot for two primary reasons: Pressure and radiogenic heating make it very hot deep in the Earth (about 100 km down) where rocks melt to make magma. The rock around the magma is a good insulator so the magma doesn’t lose much heat on the way to the surface.

What happens if you touch lava?

Dipping your hand into molten rock won’t kill you instantly, but it will give you severe, painful burns — “the kind that destroy nerve endings and boil subcutaneous fat,” says David Damby, a research chemist at the USGS Volcano Science Center, in an email to The Verge. Now, falling into lava is another story.

What happens if you pee in lava?

While exploring an active volcano, Dante Lopardo decided to urinate on some molten rock, which has a temperature of about 700°C. As seen in the video Lopardo took, the pee instantly vaporizes as it hits the liquid rock and the lava sizzles. It also leaves something of a charred black mark after sizzling off.

Can lava melt a diamond?

To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.

Is lava hotter than the sun?

Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can’t hold a candle to the sun! At its surface (called the “photosphere”), the sun’s temperature is a whopping 10,000° F! That’s about five times hotter than the hottest lava on Earth.

How cold is the moon?

The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.

What’s the hottest thing in the universe?

The hottest thing in the Universe: Supernova

The temperatures at the core during the explosion soar up to 100 billion degrees Celsius, 6000 times the temperature of the Sun’s core.

What is the hottest organ?

Surprisingly, your liver is the organ that generates the majority of your body temperatue. This is due to the amount of metabolic activity taking place and is therefore the hottest part of the body (internally.)

What’s the hottest part of a woman’s body?

The warmest parts of the human body are the head, chest and armpits, according to the Journal Gazette.

Which is the hardest part in our body?

Tooth enamel

Tooth enamel is the first line of defense your teeth have against plaque and cavities. It is the white, visible part of the tooth and it is also the hardest part of the human body.

What is the coolest organ in the body?

Your liver does three main jobs: It filters harmful things from your blood, stores fuel, and makes a liquid called bile that helps you digest food. But that’s just the beginning. This amazing organ plays a part in hundreds of other bodily functions.

What is the most useless organ?

The appendix

The appendix may be the most commonly known useless organ.
While plant-eating vertebrates still rely on their appendix to help process plants, the organ is not part of the human digestive system.

Which part of the human body does not rest?

Correct Option: D. Heart is the only organ in the body which never rest throughout the entire life. The heart is a hollow muscle that pumps blood throughout the blood vessels by repeated, rhythmic contractions.
