The Indonesian archipelago is located on the Ring of Fire, an area of high volcanic and seismic activity that circles the Pacific Ocean. The area is home to about 75 percent of the world’s active and dormant volcanoes. The two plates that create the volcanoes in Indonesia are the Indo-Australian Plate and the Pacific Plate.
The Indo-Australian Plate is a large, relatively thin plate that is made up of the crust and upper mantle of the Indian and Australian continents. The Pacific Plate is a much smaller plate that is made up of the oceanic crust of the Pacific Ocean. The two plates move towards each other at a rate of about 5.5 cm (2.2 inches) per year.
The collision of the two plates creates a subduction zone, where the Pacific Plate slides underneath the Indo-Australian Plate. This creates a series of earthquakes and volcanoes along the plate boundary. The Indo-Australian Plate is pushing up the Himalayas, and the the Pacific Plate is pushing up the Andes.
The most active volcanoes in Indonesia are located on the Sunda Arc, a chain of volcanoes that runs along the western edge of the archipelago. The most active volcano is Mount Merapi, which has erupted more than 30 times since 1548. The most recent eruption was in 2010.
The Sunda Arc is caused by the collision of the Pacific Plate and the Sunda Plate. The Pacific Plate is sliding under the Sunda Plate, causing the Sunda Plate to buckle and push up the volcanoes along the arc.
The volcanoes in Indonesia are a beautiful but dangerous part of the country. They are a major tourist attraction, but visitors need to be aware of the potential for eruptions.

What two plates come together to produce the volcanoes of Indonesia?
Volcanoes are created when two plates collide. The Pacific Plate and the Eurasian Plate are two of the plates that meet in Indonesia, which is why the country has so many volcanoes. The two plates grind against each other, creating mountains. The pressure of the two plates against each other eventually builds up until the mountains become so tall that the pressure is too much. The pressure causes the mountains to break and the molten rock, called magma, to escape. The magma flows out of the mountain and forms a volcano.
The two plates that meet in Indonesia are the Pacific Plate and the Eurasian Plate. The Pacific Plate is made up of the Pacific Rim, which is the area around the Pacific Ocean. The Pacific Rim is made up of a lot of small plates that move around. The Eurasian Plate is made up of Europe and Asia. The two plates meet in Indonesia because the Pacific Plate is moving towards the Eurasian Plate.

The Eurasian Plate is made up of a lot of big plates that don’t move around very much.

The pressure of the two plates against each other is too much for the Pacific Plate, so the Pacific Plate breaks and the magma escapes.
What two plates cause volcanoes?
Volcanoes are a very important part of the Earth’s geology. They are formed when two plates collide. The force of the collision causes the Earth’s mantle to melt and rise to the surface. This molten rock is called magma. When the magma reaches the surface, it becomes a volcano.
There are two types of volcanoes: shield volcanoes and stratovolcanoes. Stratovolcanoes are the most common type. They are made of layers of ash, lava, and rock. Shield volcanoes are made of much softer rock. They are wider than stratovolcanoes and have a more gentle slope.
Volcanoes can be dangerous. They can produce ash, lava, and gas that can be harmful to people and animals. They can also produce floods called lahars. Lahars are made of water, ash, and rock. They can be very dangerous to people and property.

What are the two plates involved in forming islands in Indonesia?
There are two main plates that are involved in forming the islands in Indonesia – the Sunda Plate and the Eurasian Plate. The Sunda Plate is located in the eastern part of Indonesia, and the Eurasian Plate is located in the western part of Indonesia. The two plates are moving towards each other, and this is causing the islands in Indonesia to form.
The Sunda Plate is a small plate that is located in the eastern part of Indonesia. The Sunda Plate is being pushed towards the Eurasian Plate by the Pacific Plate. The Eurasian Plate is a large plate that is located in the western part of Indonesia. The Eurasian Plate is being pushed towards the Sunda Plate by the Indian Plate. The two plates are moving towards each other, and this is causing the islands in Indonesia to form.
The Sunda Plate and the Eurasian Plate are both made up of continental crust. The continental crust is the thickest and most solid layer of the Earth’s crust. The continental crust is made up of rocks that are known as granites. The granites are very hard and resistant to erosion. The rocks on the continental crust are also very old, and they have been through a lot of changes over time.
The continental crust is sitting on top of the Earth’s mantle. The mantle is made up of hot rocks that are in a liquid state. The mantle is responsible for the movement of the plates on the Earth’s surface. The mantle is moving the plates around, and this is causing the islands in Indonesia to form.
The two plates are moving towards each other at a rate of about 5-6 cm per year. The movement of the plates is causing the mountains to form, and it is also causing the earthquakes and volcanoes to occur. The two plates will eventually collide, and this will cause the islands in Indonesia to disappear.
What type of plate boundary is in Indonesia?
There are three types of plate boundaries: convergent, divergent, and transform. Indonesia is located on a convergent plate boundary.
A convergent plate boundary is when two plates collide. The plate on the top (the plate with the heavier rock) will push the plate on the bottom (the plate with the lighter rock) down. This can cause the plates to buckle and fold. This can also cause earthquakes and volcanoes.
The plate boundary in Indonesia is located in the Sunda Arc. The Sunda Arc is a region where the Indo-Australian Plate and the Eurasian Plate collide. This is the most active plate boundary in the world and has caused numerous earthquakes and volcanoes. The most recent major earthquake occurred in 2004, when the Sumatran fault ruptured, causing a magnitude 9.3 earthquake. This was the deadliest earthquake in history, killing more than 230,000 people.
What type of plate is plate A?
Plate A is a type of plate that is used to serve food. It is usually made from ceramic or porcelain, and is often decorated with a design or pattern. Plate A is a common choice for restaurants and other food service businesses.
What is formed when two continental plates collide?
When two continental plates collide, the force of the impact creates mountains. The mountains are formed when the earth’s crust is forced upwards. The mountains can be very large, and can be formed over a large area. The mountains can also be very tall, and can be a major feature of the landscape.
How do plate boundaries cause volcanoes?
Volcanoes are mountains that have formed when hot molten rock (magma) and ash escape from an opening in the Earth’s surface. The molten rock and ash become solid as they cool and this makes a volcano.
Volcanoes are found at plate boundaries. A plate boundary is the area where two plates meet. The Earth’s crust is made up of several large plates that move around on the Earth’s surface. The plates move very slowly and the boundaries between them are called faults.
Volcanoes form at plate boundaries because the plates are moving and pushing against each other. The pressure of the plates causes the molten rock and ash to escape from the Earth’s surface. The molten rock and ash can also be forced out by the movement of the Earth’s mantle (the layer of the Earth below the crust).
There are three types of plate boundaries:
– Convergent boundaries: two plates move towards each other and one plate is pushed under the other. This type of boundary is found where an oceanic plate and a continental plate meet. The oceanic plate is pushed under the continental plate and this causes the mantle to heat up. This heat causes the molten rock and ash to escape from the Earth’s surface and form a volcano.
– Divergent boundaries: two plates move away from each other. This type of boundary is found where an oceanic plate and a continental plate meet. The oceanic plate is pushed down into the mantle and this causes the mantle to heat up. This heat causes the molten rock and ash to escape from the Earth’s surface and form a volcano.
– Transform boundaries: two plates move past each other. This type of boundary is found where two continental plates meet. The plates move very slowly and the boundary is called a fault. The molten rock and ash can escape from the Earth’s surface at a fault, but it is not as common as it is at other types of boundaries.
