in a colliding boundary two plates move towards each other. one of the plates moves toards the magma and malts with it, because magma is less dense than the rocks on the plates the magma rises to through holes in the plate. gasses get trapped in the lava forming preassure of heat and magma and gasses, when the preassure becomes intense the magma explodes

What are the segments of the earth's outer surface called?
The segments of the Earth's outer surface are called tectonic plates. These plates float on the semi-fluid asthenosphere beneath them and interact with one another, causing processes such as earthquakes, volcanic eruptions, and the formation of mountains.
How does volcanoes change the Earth's atmosphere?
Volcanoes release large amounts of ash, sulfur dioxide, and other gases into the atmosphere during eruptions. These particles and gases can affect climate by blocking sunlight and causing cooling, or by contributing to the greenhouse effect and causing warming. Volcanic eruptions can also create new clouds and alter weather patterns in the short term.
Who theorized volcanic theory?
The theory of volcanic activity was proposed by the Roman naturalist Pliny the Elder in the 1st century AD. He described the role of magma beneath the Earth's surface in causing volcanic eruptions.
How can volcanic eruptions lead to earthquakes?
Volcanic eruptions can lead to earthquakes due to the movement of magma beneath the surface, causing pressure buildup in the Earth's crust. As the magma pushes its way to the surface, it can trigger seismic activity by fracturing and shifting the surrounding rock. Additionally, the explosive force of the eruption can also induce seismic disturbances in the vicinity of the volcano.
Why is a volcano an opening in the earth's crust?
A volcano is an opening in the earth's crust because it allows magma from beneath the surface to reach the surface, causing volcanic eruptions. Magma is molten rock located beneath the Earth's surface, and when it erupts through a volcano, it can create new landforms and release gases and ash.
What do you know about the changes on the surface of the earth?
volcanic eruptions
What are the segments of the earth's outer surface called?
The segments of the Earth's outer surface are called tectonic plates. These plates float on the semi-fluid asthenosphere beneath them and interact with one another, causing processes such as earthquakes, volcanic eruptions, and the formation of mountains.
Why volcanic eruptions?
The earth's plates shift and magma is forced up through the earth's surface.
What is one way that the earth's surface changes quickly?
One way that the earth's surface changes quickly is that the earth's surface natural substances can be researched by mining or digging into the earth.
How can volcanic eruptions chang the surface of the earth?
By creating new islands and lands
Why volcanic eruptions exist?
The earth's plates shift and magma is forced up through the earth's surface.
What changes take place on the earth surface?
Volcanoes and earth slides are two ways that earth's surface change quickly.

How are magmatic materials transported to the surface?
Magmatic materials are transported to the surface through volcanic eruptions. When pressure builds up in the magma chamber below the surface, it can force the magma to erupt through a vent or fissure, releasing gases and molten rock onto the Earth's surface. This process can result in different types of volcanic eruptions, such as explosive eruptions or effusive eruptions.
How can volcanic eruptions lead to earthquakes?
Volcanic eruptions can lead to earthquakes due to the movement of magma beneath the surface, causing pressure buildup in the Earth's crust. As the magma pushes its way to the surface, it can trigger seismic activity by fracturing and shifting the surrounding rock.

What is the rain causing to happen to the surface of the earth?
erosion
