A. A volcano is an erupting mountain or island.B. A volcano is a natural disaster.C. A volcano is a place where ash and gas escape from the earth.D. A volcano is a place where molten rock, ash, and gas escape from the earth.
What are the 3 main causes of volcanic eruptions?
Volcanoes are created when molten rock called magma rises to the surface from the Earth’s mantle. The magma is heated by the Earth’s heat, and when it gets too thick, the pressure from the magma can break through the Earth’s surface. The magma then rises to the surface and starts to form new volcanoes. The other two main causes of volcanic eruptions are when ash and gas escape from the volcano and when molten rock called magma and ash escape from the volcano.
What are volcanoes Class 7?
A volcano is a type of mountain that is made from ash, rock, and magma. These mountains can be very large, and can be as high as 6,000 feet.
What is the difference between composite and shield volcanoes?
A shield volcano is a type of volcano that is made up of a series of shield mountains. Shield volcanoes are less common than composite volcanoes, but they can be more powerful. Composite volcanoes are made up of a series of volcano cones.
What is a volcano for kids?
A volcano is a place where hot molten rock called magma is under the earth’s surface. When the magma is ready, it causes the earth to erupt.
What type of volcano is Mount Fuji?
A volcano is a natural place where hot molten rock, ash, and gas escape from the Earth.
What is a volcano Class 6?
A volcano is a class 6 volcano.
What are three types of volcanoes and where are they found?
Volcanoes are found in many parts of the world. Three types of volcanoes are the Andes, the Himalayas, and the Andes of South America.
What is a small volcanic cone called?
A small volcanic cone is a cone that is less than a kilometer wide and is less than a kilometer high.
What Mount has 3 volcanic cones?
How many types of lava are there?
There are three types of lava: magma, ash, and lava.
How many volcanoes are there in the world?
There are over 20,000 volcanoes in the world.
What is the largest volcano in the world?
The Mount Kilimanjaro volcano is the largest volcano in the world. It is located in Tanzania and is about 8,850 feet (2,815 meters) tall.
What are the two secondary types of volcanoes?
Volcanoes are cones of molten rock that rise from the earth’s surface. They are usually located in areas with a strong seismic activity, such as the Pacific Northwest, the Andes, and the Hawaiian Islands. Volcanoes can erupt, often causing widespread destruction and loss of life, or they can form dormant volcanoes that can remain inactive for many years.
What are the 3 types of volcano according to the shape of their cones?
Volcanoes are classified according to their shape of their cones – round, square, or cones.
What are the differences between the four types of volcanoes?
The four types of volcanoes are:1. Volcanic: These are the most active volcanoes and can erupt any time.2. tephra: This is the ash that is left after an eruption.3. ash: This is the solidified gas that is left after an eruption.4. lava: This is the hot gas that is left after an eruption.
What are the 4 types of volcano according to their appearance?
Volcanoes are typically classified by their appearance: active, dormant, extinct, or tectonic. Active volcanoes are the most active, while dormant volcanoes are the most inactive. Extinct volcanoes are the most extinct, and tectonic volcanoes are the most active.
What is the biggest ever volcanic eruption?
The most recent major eruption on the planet is the Krakatoa eruption, which occurred in 1883. The eruption was so large that it created a plume of ash that reached as high as 12,000 feet in the atmosphere.
What are mini volcanoes called?
A mini volcano is a volcano that is smaller than a full-sized volcano.
What are volcanic mountains for Class 6?
Volcanoes are mountains that are built from the ash and rocks that are left when the earth’s molten rock, called magma, melts. When the magma is very hot, it forms a pressure cooker called a volcano. The pressure in the volcano makes the ash and rocks rise up and form the mountain.
Which type of volcano is the most explosive?
A. VolcanicB. TectonicC. Volcanic-StratovolcanoD. Volcanic-Eruptive
What is the difference of active and inactive volcano?
Active volcanoes are those that are in eruption or are about to erupt. Inactive volcanoes are those that are not in eruption or have been inactive for a period of time.
What are the different kinds of volcanoes explain with examples?
Volcanoes are formed when molten rock called magma rises to the surface from the Earth’s mantle. The magma is made up of solid rock and gas. When the magma is heated, it starts to melt. This liquid magma rises to the surface and forms a volcano. The different kinds of volcanoes can be explained with examples.
What are the different types of volcanoes according to activity?
There are three main types of volcanoes according to their activity: eruptive, magma-forming, and extinct.
What is the safest type of volcano?
The most unsafe type of volcano is a volcano that is active and has the potential to blow up.
What are the different states of volcanoes called?
The different states of volcanoes are called tectonic plates, and the different plates are moving around on the Earth’s surface. The Earth’s surface is divided into many different regions, and each region has its own set of tectonic plates.
What are the two primary types of volcanoes?
Volcanoes are mountains with a hole in the middle. They erupt molten rock and ash, which can be seen from a distance.
What are the 5 volcano types?
The 5 volcano types are:-Apyroclastic-Mafioso-Volcanic-Tectonic-Aurora
What are the 6 types of volcanic eruptions?
Volcanoes are created when molten rock, ash, gas, and other materials come together to form a new volcano. The molten rock (magma) is heated by the Earth’s surface temperature. This causes the ash to rise to the surface and the gas to escape. The new volcano will continue to grow until the pressure from the ash and gas builds up and the volcano explodes.
What are the 3 types of volcanoes?
A. Volcanoes are mountains that erupt, making ash and lava.B. Volcanoes are mountains that blow ash and gas out of their summit.C. Volcanoes are mountains that erupt, making ash, rocks, and lava.
How hot is lava?
Lava is very hot.
