Question 2

types of volcanoes? there are many different types of volcanoes and these are some I found. Shield volcanoes: A shield volcano is a big volcano with sloping sides. Stratovalcanoes: A stratovolcano is also also known as a composite volcano, is a very tall, conical volcano, it is composed of many layers of lava, tephra, and volcanic ash. Super volcanoes: A supervolcano is a volcano that produces the largest and most voluminous kind of eruptions on Earth. Submarine volcanoes: A Submarine volcanoe is an underwater fissure under the ocean surface from which magma can erupt.Subglacial volcanoes: A subglacial volcano is a volcanic form produced by eruptions beneath the surface of a lake; it melts into a glacier or ice sheet by the rising lava.

Question 1

what are volcanos and how are they formed? A volcano is like a vent, or opening, in the earth's crust where melted rock better known as molten rock called magma is ejected. We also use the word "volcano" to describe the mountain that is built up by the molten rock and ashes. The temperature deep inside the earth is very hot, so hot it will melt rock into a super-really-hot liquid which is called magma. and It also builds up a lot of pressure. the built up pressure pushes the magma, along with gases and steam, which goes up through openings in the earth's crust. Parts of a Volcano scribe the mountain that is built up by the molten rock and ashes.

volcano information

here is some basic information i found on volcanoes


When thick magma and large amounts of gas build up under the surface, eruptions can be explosive, expelling lava, rocks and ash into the air. Less gas and more viscous magma usually mean a less dramatic eruption, often causing streams of lava to ooze from the vent.
The mountain-like mounds that we associate with volcanoes are what remain after the material spewed during eruptions has collected and hardened around the vent. This can happen over a period of weeks or many millions of years.
A large eruption can be extremely dangerous for people living near a volcano. Flows of searing lava, which can reach 2,000 degrees Fahrenheit (1,250 degrees Celsius) or more, can be released, burning everything in its path, including whole towns. Boulders of hardening lava can rain down on villages. Mud flows from rapidly melting snow can strip mountains and valleys bare and bury towns. Ash and toxic gases can cause lung damage and other problems, particularly for infants and the elderly. Scientists estimate that more than 260,000 people have died in the past 300 years from volcanic eruptions and their aftermath.
Volcanoes tend to exist along the edges between tectonic plates, massive rock slabs that make up Earth's surface. About 90 percent of all volcanoes exist within the Ring of Fire along the edges of the Pacific Ocean.
About 1,900 volcanoes on Earth are considered active, meaning they show some level of activity and are likely to explode again. Many other volcanoes are dormant, showing no current signs of exploding but likely to become active at some point in the future. Others are considered extinct.
