How Volcano Is Formed Game Quiz Online

This a How Volcano Is Formed Game Quiz Online for students in 5th, 6th, 7th, 8th grades. In this game, students will learn about volcanoes, their different parts, the crater, magma chamber, vents and more. The diagram of a volcano can teach us these different parts in a structured way. Volcanoes are either dormant or active. The later still erupt from time to time while the former no longer erupt. Volcanoes create tall hills that punctuate the landscape in a fascinating way. In this game, students will learn about main characteristics of volcanoes, how they erupt, lava flow, formation and more. This game is for classrooms and homeschool.


How Volcano Is Formed Game. Learn the parts of a volcano.

Parts of a Volcano

If you have ever wondered how a volcano erupts, you should have also wondered about its various parts. One of the most important parts of a volcano is its magma chamber, which stores molten magma from the depths of the earth. This molten rock comes from the Earth's mantle and is propelled by pressure and ejected from the volcano as lava. Check out an interactive diagram of a volcano in the games section to better understand the structure of one.

Cinder cones emit lava

What are cinder cones? They are small, steep cones made of lava cinders, or magma-hardened particles. Unlike other volcano types, cinder cones emit little lava, because most of the lava is turned into ash. They are also smaller in size than other types. Famous examples of cinder cones include Mt. Vesuvius.

There are many other cinder cones around the world, but the ones in California have at least five lava flows. The United States Geological Survey has tracked five lava flows from the cinder cone. You can view each one individually by visiting the cinder cone's summit. It's a great way to see what the lava cones look like. Just be sure to follow the eruption's path as you'll get closer to the cinder cone.

While cinder cones are the most common type of volcanic activity, there are a few special hazards associated with them. During an eruption, lava burrows out from the cinder cone's bottom, lifting the cinders that are not dense enough to survive the heat. These fall back as ash and toxic gas plumes in surrounding areas. These are devastating for people living around such places.

They have a flat top with a wide circular crater

Cones are formed when magma builds up at a volcanic vent instead of erupting into the air. They look similar to a dome, but are smaller. A dome is formed by an eruption that is more violent than the usual kind.

The crater is surrounded by steep walls. Larger craters may slope and form terraces that descend into the crater. Some volcanoes even have glaciers in their craters. However, not all volcanoes are formed this way. There are also composite volcanoes. 

The term crater can refer to a wide circle or a flat top. These cones can be either intrusive or extrusive. The former are cooled at the surface, while the latter are hidden underground. Intrusive igneous rocks are exposed by erosion. 

A cone has a flat top with a large circular crater. The crater is also called the summit crater. The summit crater of a volcano is the rim of a cone. The rim is lower than the top, but it is still an elongated depression.

They have a secondary vent

Large volcanoes have several vents, called secondary vents, which are connected to the underground magma chamber. During eruptions, most of the material comes out of this central vent. However, sometimes the central vent is plugged and magma must find another way to reach the surface. Secondary vents form satellite cones, adventitious cones, and parasitic cones. Sometimes they form large volcanoes themselves.

They have a lava flow

A lava flow is a form of volcanic activity in which hot lava flows through cold seawater or land. These flows form cinder cones, shield volcanoes, and compound volcanoes. Lava also flows through other types of vents, such as fissures. Some lava flows are so large that they cover the entire ocean floor, while others move toward the highest mountain in a region, such as Mauna Kea on Hawaii's Big Island.

The lava flow from a large volcano is very hot, with temperatures ranging from 700 degrees Celsius to 2,000 degrees Fahrenheit. Molten rock begins to rise toward the earth's surface when the temperature reaches this point. Parts of a volcano consist of several different parts, including a magma chamber, a vent, and a crater where the lava flow is formed.

A lava flow with low viscosity is more likely to be smooth. The lava may be several dozen meters high. High viscosity lava can accumulate to a considerable thickness, and pressure ridges and contraction fractures disrupt the surface of the flow. This causes an irregular surface and often leads to an explosion. The lava flow from Opal Cone was a lava flow.

A lava flow is the least dangerous type of volcanic eruption. Most flows move slowly enough to avoid human casualties, but an example of a dangerous lava flow is the 1979 eruption of Nyiragongo. This lava flow, which escaped through fissures created during an early eruption, moved more than three hundred kilometers and contained more than 1.5 million cubic kilometers of lava. The lava flow reached the city of Goma and caused great damage.

They produce ash clouds

Volcanic ash consists of tiny, fissured particles that can be dangerous if inhaled. Even if they are less than 1/12 inch in diameter, ash particles can be dangerous if inhaled. If the ash cloud is thick enough, it can affect aviation, agriculture, water supplies, and even human health. Ash particles can also affect the climate around the world. For this reason, proper safety equipment is necessary for any volcano visitor.

In the event of a volcanic eruption, ash clouds are often visible in the sky. These clouds are a result of hot volcanoes filled with lava. Depending on the height and location of an eruption, ash particles can be hundreds of kilometers across. During an eruption, about 2% of the ash mass can remain in the atmosphere. This fraction can be difficult to capture. Despite these difficulties, however, scientists have developed a number of methods for measuring the size distribution of volcanic ash. These techniques include scanning electron microscope analysis and laser diffraction.

In addition to ash particles, volcanic ash also releases sulfur dioxide and other gasses. They enter the stratosphere, where they combine with water to form sulfuric acid aerosols that reflect solar radiation and cool the Earth's surface. While sulfur dioxide and ash particles have a direct impact on local climate, the smaller, finer-grained particles are transported thousands of kilometers. Sometimes they even orbit the earth.

They can be dangerous

The gasses released during a volcanic eruption are one of the most dangerous aspects of a volcano. Most of the gasses are water vapor, but other dangerous chemicals are also present. Sulfur dioxide, for example, is extremely dangerous to humans, as it can cause respiratory problems in healthy people and damage vegetation. Carbon dioxide, on the other hand, is heavier than air and extremely dangerous to animals. The explosion of a volcano can also release large amounts of one or both of these gasses.

Typical volcanic gasses are very toxic. Even a moderate eruption can be fatal. Carbon dioxide has a higher density than air, and large amounts of CO2 can kill large populations. For example, the 1986 Lake Nyos eruption was a disaster that released tons of carbon dioxide and drowned three villages. Today, scientists monitor carbon dioxide emissions from volcanoes to ensure they do not cause further damage.

Lava from a volcano can be dangerous in rare cases, but it is not as deadly as you might think. Lava from a volcano is liquid and can travel a great distance. In the Democratic Republic of Congo, a recent eruption resulted in a lava flow that killed dozens of people. There are other hazards associated with volcanoes that you should be aware of. In any case, it is important that you stay in a safe place to avoid volcanic hazards.
