WhatMolten rock rises to the earth surface causing these eruptions?

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

Where are Earth's volcanoes located on Earth's surface?
inside whats called earths ring of fire where there has been the most volcano eruptions
Do Volcanic eruptions affect earth's atmosphere?
Yes. Volcanic eruptions typically release dust and other particles which shield the earth from the sun, producing a cooling effect. Some greenhouse gases, particularly carbon dioxide, can be released, causing a warming effect.
How are earth layers formed?
sedimenatary rock create layers in the surface of the earth and eruptions from volcanoes also make layers of the earth.
What would Earth's surface look like if there were no mountain uplift or erosion?
The earth's surface would look like what it is now except with no more new volcanoes, no more volcanic eruptions and no more earthquakes or natural disasters.
Describe one way that earthquakes can change earth's surface rapidly?
By causing landslides or floods.
What do you know about the changes on the surface of the earth?
volcanic eruptions
Why volcanic eruptions?
The earth's plates shift and magma is forced up through the earth's surface.
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.
Are earthquakes the only things that cause volcanic eruptions?
No. Eruptions are caused by magma moving up from the mantle. Earthquakes can be a sign of magma pushing the earth out of its way (causing the earthquake) which lead to the eruptions and potentially tsunamis.
How did plate tectonics cause the formation of the hawaiian island?
The shifting of plates in the earth cause massive underwaer volcanic eruptions. Over time, the eruptions of the volcanoes cause a buildup of dried lava that eventually breached the surface of the ocean. These volcanoes are still erupting, causing the island to gradually grow.
What is the rain causing to happen to the surface of the earth?
erosion
Where are Earth's volcanoes located on Earth's surface?
inside whats called earths ring of fire where there has been the most volcano eruptions
What are the fast changes on Earth?
Floods, volcanic eruptions, and landslides are all examples of rapid changes at the surface.
When pieces of the earth's surface rub against each other the Earth shakes causing?
an earthquake
Do Volcanic eruptions affect earth's atmosphere?
Yes. Volcanic eruptions typically release dust and other particles which shield the earth from the sun, producing a cooling effect. Some greenhouse gases, particularly carbon dioxide, can be released, causing a warming effect.
