How volcanoes occur?
Volcanoes occur when the earth cools off, and releases internal heat and pressure. Magma is a lower density than the surrounding rocks, and this causes it to rise to the surface. As it rises, gas bubbles form in the magma, exerting pressure, causing the magma to erupt out of the surface of the earth.
What stress causes volcanoes?
Volcanoes are primarily caused by tectonic plate movements and the release of pressure from the Earth's mantle. Stress from these movements and pressure can lead to magma rising to the surface and resulting in volcanic eruptions. Other factors such as the composition of the magma and the presence of water and gases can also influence volcanic activity.
What layer of the earth causes volcanoes?
Volcanoes are primarily caused by activity in the Earth's mantle, which is the layer located beneath the crust. Magma, which is molten rock beneath the Earth's surface, can rise through cracks in the crust, leading to volcanic eruptions. The movement of tectonic plates can also play a role in the formation of volcanoes.
How do volcanoes affect other earth systems?
They burn everything
What sphere do volcanoes occur in?
Volcanoes occur in the geosphere, which is the solid part of the Earth made up of rocks, minerals, and landforms. They are typically found at plate boundaries where tectonic activity causes magma to rise to the surface.
What are some causes for the changing of Earth's surface?
plate tectonics, mid ocean ridge
What are the significance of volcanoes in the earth's surface?
it is a meteorite made by a volcanoes
Where are volcanoes found on earth's surface?
volanoes
Do volcanoes occur randomly over Earth's surface?
Volcanoes do not occur randomly over Earth's surface. They occur along the located mark of plate boundaries.
Planet known to have volcanoes on its surface?
Venus, Earth, and Mars are all planets with volcanoes.
What layer of earth causes volcanoes?
The very center

What are the causes and effects of volcanoes?
the effect of a volcano are te blow up , and this is caused by bombs

How volcanoes affect Earth's surface?
Volcanoes can change the surface of the earth in several ways. The lava that is ejected for the volcano may dry and form a new layer of sediment on the ground. The chambers of magma underground can become too pressurized and make a whole new volcanic mountain. Hope that answers your question!
