When a volcano erupts hot gases
When a volcano erupts, hot gases and melted rock from deep within Earth find their way up to the surface. This material may flow slowly out of a fissure, or crack, in the ground, or it may explode suddenly into the air. Volcanic eruptions may be very destructive. But they also create new landforms.
What are the harmful effects of plastic Class 8
Both creation and recycling of plastic produce toxic gases and residues which causes air and water and land pollution. Few additives such as phthalates etc. which are added in plastics to prevent its structure may cause serious hormonal imbalance in males and females. Plastic causes many fire hazards.
Why do volcanoes erupt kids
Magma is lighter than rock so rises towards the Earth's surface. As the magma rises, bubbles of gas form inside it. Runny magma erupts through openings or vents in the earth's crust before flowing onto its surface as lava. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises.
How do volcanoes form for kids
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.
How can we say no to plastic
Here are some useful tips:Drink tap water or buy glass bottles.Avoid plastic bags.Get rid of single doses.Travel with your water bottle.Get yourself a travel kit.Avoid snacks.Pick up alternative straws.Use fabric napkins and handkerchiefs.
How does plastic harm you
Use of plastic products leads to ingestion and/or inhalation of large amounts of both microplastic particles and hundreds of toxic substances with known or suspected carcinogenic, developmental, or endocrine-disrupting impacts.
How hot is lava
1,300 to 2,200 °F
The temperatures of molten lava range from about 700 to 1,200 °C (1,300 to 2,200 °F). The material can be very fluid, flowing almost like syrup, or it can be extremely stiff, scarcely flowing at all.
How old is the oldest volcano
The oldest volcano in the chain is the inactive volcano Meiji, which is 85 million years old. So to answer your original question, volcanoes have been erupting on Earth for at least the last 4 billion years and were undoubtedly more active in the distant past than they are today.
How far can lava shoot
Lava fountains can propel lava 1,000-2,000 feet (300-600 m) above the volcano. The gas dissolved inside the magma is the driving force. As the magma approaches the surface the pressure on it decreases.
Can we go without plastic
Without plastics, food waste would increase. Without plastics, fuel costs would increase due to the heavier vehicles. Without plastics, medical care would be very difficult if not impossible. In fact, we generate so much plastic that every hour, waste equal to 2,000 trucks is created.
Can you be plastic free
Learning how to live without plastic can feel like an impossible task, but it's easier than you may think to cut back on how much you consume. The majority of the most polluting plastic products can be replaced with a more sustainable option that works for both your family and the planet.

Is plastic should be banned
Plastic bags never degrade completely, which shows that as more of them are produced by companies, more are introduced into the environment. Therefore, the more the amount of plastic bags, the more there is plastic pollution and its effects. Banning the use of plastic bags will help reduce this great effect.
Is Blue Lava real
Blue lava, also known as Api Biru, and simply referred to as blue fire or sulfur fire, is a phenomenon that occurs when sulfur burns. It is an electric-blue flame that has the illusory appearance of lava.
Can lava melt steel
First, although lava at 2,000 degrees F can melt many materials in our trash — including food scraps, paper, plastics, glass and some metals — it's not hot enough to melt many other common materials, including steel, nickel and iron.
Did a 75 year old fall into a volcano
Man, 75, dies after falling out of viewing area and into Hawaii's active Kilauea Volcano: Rescuers found his body 100 feet below crater rim. The lifeless body of a 75-year-old Hawaii man was found after he apparently fell 100 feet into the crater of the most active volcano on the Big Island, authorities said.
What can’t melt lava
We conclude that the optimal heat generated by lava at 2,190°F cannot melt the tungsten because of its high melting point. Other examples of metals and ceramics that can withstand lava's temperature include; titanium, iridium, iron alloys, osmium, nickel alloys, aluminum oxide, mullite, and silicon nitride.
Can you touch lava quickly
Lava won't kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn't get out, you wouldn't die. With prolonged contact, the amount of lava "coverage" and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!
What if plastic didn t exist
Without plastic, you also wouldn't be able to use electricity, there would be no plastic circuits to build your phone or computer. There would be no inexpensive adapters either. We also wouldn't be able to protect wildlife like rhinos from becoming extinct, nor would we be able to keep ourselves safe.
Can plastic exist naturally
Definition. Plastics are a group of materials, either synthetic or naturally occurring, that may be shaped when soft and then hardened to retain the given shape.

Which country is plastic free
Rwanda. In 2008, it became the world's first 'plastic-free' nation, 10 years after it introduced a ban on all plastic bags and plastic packaging. Unlike many other countries, Rwanda is strict at enforcing its ban. Anyone caught with a plastic item in the country faces a jail sentence of up to six months.
Has plastic ever been alive
Anything metal, plastic or stone has never been alive.
Is it OK to use plastic
Plastics are ubiquitous, cheap and convenient, but come with a hidden cost: they leach chemicals that contaminate our food and drink, and they create enduring pollution.
Is it bad to wear plastic
Plastics are created with the use of various chemicals, and some of these chemicals, such as BPA, have proven health risks. Concerns about these chemicals are focused mostly on food and drinks containers; the risks from wearing plastic are thought to be much lower, but not necessarily absent.
