Why doesn't Minnesota have major earthquakes or volcanoes?
because there is no tectonic plate under Minnesota, no plates are ever moving over MN, thus making it hard to get an earthquakes and volcanoes usually occur @ the edge of plates
What is responsible for earthquakes and volcanoes?
Pressure under ground is responsible for volcanoes.
Do earthquakes happen everywhere volcanoes are?
They do occur where volcanoes are, but it is not because of the volcanoes itself. It is because under the earth's surface there are tectonic plates (plates that make up the earth's crust) that shift, and occasionally collide into one another. This is what causes the ground to shake. This shaking is what we interpret as earthquakes.
Where do earthquakes and volcanos occur?
Volcanoes tend to form at convergent tectonic plate boundaries where subduction is occurring (such as the western coast of South America) and at divergent plate boundaries where two tectonic plates are moving apart (e.g. the Mid-Atlantic-Ridge and Iceland). Earthquakes also occur at convergent boundaries and in fact these tend to cause the strongest earthquakes. Earthquakes also occur at transform boundaries (such as the San Andreas fault) however these do not tend to cause the formation of volcanoes. So to find volcanoes and large earthquakes you should be looking at convergent plate boundaries where subduction is occurring.
What causes volcanoes to erupt under earths surface?
mostly earthquakes or plate tectonic movement.
Where regional (prograde) occur?
Retrograde metamorphism involves the reconstitution of a rock via revolatisation under decreasing temperatures (and usually pressures),
What is the difference between thermal metamorphism and regional metamorphism?
thermal is when the rock is metamorphosed by heat more than pressure. regional is the opposite. so if a rock is close to the surface and gets metamorphosed next to a pluton, it is mainly heat (its not very deep, so there is not a lot of pressure, but it gets a lot of heat from the pluton). but if a rock is very deep and far from any magma, it will be under a lot of pressure, but not a lot of heat. so thus, regional metamorphism.
What type of rock can only form deeply underground?
Only an intrusive igneous rock forms underground, but you can argue that all metamorphism occurs underground. The issue here is that when the metamorphism is thermal, often the ground it is under has only just been formed (i.e. a lava flow). To avoid confusion, only regional metamorphism can take place underground. The rocks formed by regional metamorphism and intrusive magma cooling are rocks with crystalline texture.
What are those active volcanoes under the sea in the Philippines?
The active volcanoes under the Philippines are part of the Ring of Fire in the Pacific Ocean. The Ring of Fire and the Pacific Plate are where the majority of earthquakes and volcanic eruptions occur.
Are volcanoes made by plates sliding away from each other?
Many are but many others are not. Most volcanoes on land occur where two plates press into each other and one slide slides under the other. Some volcanoes occur at hot spots, which are not related to plate boundaries.
Where does the eruption of lava occur?
right beneath the thin crust of the lava that was dried and under the volcanoes in alot of cavities
Can frogs sprout from mud in ponds?
No, spontaneous generation does not occur.
What causes metamorphic rocks?
A metaporphic rock is formed when a rock is put under extreame heat and preasure for many (often thousands or millions) of years. This changes it into a new type of rock. This new rock is called a Metamorphic rock.
Do volcanoes live under the sea?
Yes, there are active volcanoes under the sea.

Why do some areas have no volcanoes?
becuase volcanoes have plates under them.the places that dont have plates under them don't have volcanoes
Can volcanoes occur on land and under the sea?
...Ever hear of Hawaii? -different person now- There aren't just lava volcanoes underwater but there are hydrothermal vents, which instead of lava, spew gas, water, and heat. They are basically underwater volcanoes. Go look at pictures of them, they're really weird. There are a very large number of underwater volcanoes at the Mid-Ocean-Ridges deep below the ocean's surface. These erupt lava directly into the ocean where it cools extremely rapidly forming pillow basalts.
