What waves from an earthquakes are known as these?
Mountains formed from the buildup of volcanic lava often take this shape
Why are volcanic rocks often exposed at Earth's surface as hills ridges and mountains surrounded by areas of lower elevation?
Volcanic rocks are often more resistant to erosion than surrounding rock
How do earthquakes form mountains?
mountains often are formed where parts of Earth's crust get pushed up from below
Are mountains made out of limestone?
They can be. Most mountain ranges form when the land is thrust upward by tectonic activity, so the type of rock present depends on what rock is present to begin with. The cores of mountain ranges, though, are often made of granite and gneiss. Volcanic mountains are not made of limestone.
What are volcanic blocks?
Volcanic Blocks are solid, irregularly shaped lumps of hardened lava, often large and boulder like in appearance; some rare volcanic blocks may weigh many tons!

What is the area that creates volcanic mountains?
There are two areas where volcanic mountains often form. They are subduction zones and hot spots.
What are the types of mountains?
There are three main types of mountains. block mountains formed by sections of the earth's crust that have been tilted or lifted up by the movement of two close fault lines, large cracks in the earth's surface. These are usually smaller than other types of mountains and are often separated by valleys. Volcanic mountains are formed by magma that is pushed out of the earth through a crack or weak place in the earth's crust. Fold mountains are formed when rock is "squeezed" together. When plates collide, the rock along the edges crumples, creating a huge zig-zag pattern in layers of the earth's crust. Upwarped mountains are formed when magma pushes up the earth's crust without breaking the surface. This creates a rounded mountain that gently slopes toward the surrounding land.

What happens when two plates collide?
They create a convergent boundary and can often create mountains, over a period of years.

Describe the process of succession in an ecosystem?
By:nevaeh Ecosystems are constantly changing in response to natural and human disturbances; Primary succession, occurs on the surfaces formed as volcanic eruptions build new islands or cover the land with lava rock or volcanic ash. In secondary succession; components often ecosystems can change by natural events such as fires, or by human activities such as farming
Why do mountains sometimes build up around a volcano?
Volcanoes are places where the melted or molten part of the earth is squeezed out onto the surface. Some volcanoes are more gentle, and the lava, or molten rock, oozes out without exploding. Hawaiian volcanoes are this sort. Other volcanoes are very explosive, sometimes blowing off their entire tops in one huge eruption, like Mt. St. Helens in the US. Volcanoes build up into mountains because as the lava flows out, it hardens into rock. The more lava that comes out, the higher the rock pile!
Why mountain formed from the build-up of volcanoic lava often take this shape?
It is cone shaped.
What are the four types of mountains and some examples of them?
Fault-block mountains formed by section of the earth's crust that have been tilted or lifted up by the movement of two close fault lines, large cracks in the earth's surface. these are usually smaller than other types of mountains and are often separated by valleys. other types of mountains are unwarped and volcanic. Volcanic mountains are formed by magma that is pushed out of the earth through a crack or weak place in the earth's crust. examples: East African Rift, Death ValleyFold mountains are formed when rock is "squeezed" together. When plates collide, the rock along the edges crumples, creating a huge up and down pattern in layers of the earth's crust. examples: Jura mountains, Ridge and Valley AppalachiansDome mountains are formed when magma pushes up the earth's crust without breaking the surface. This creates a rounded mountin that gently slopes toward the surrounding land and the magma under hardens. examples: Navajo Mountain in Utah, Bear Butte in South DakotaVolcanic mountian starts out as a simple crack in the Earth called a volcanic vent. Magma erupts out of the ground as volcanoe flows, clouds of ash, and explosions of rock. This material falls back to Earth around the vent, and piles up around it. Over time (and sometimes quite quickly) a volcanic mountain builds up, with the familiar cone shape. examples: Mt. Fuji, Mt. Vesuvius (I hoped this helped)
Is sedimentary better than volcanic rock?
It depends on the specific application or use. Sedimentary rocks are formed from the accumulation of sediments and can be more easily broken down and compacted. They often contain fossils and organic matter. Volcanic rocks are formed from volcanic activity and can be more resistant to weathering and erosion. They often have a more uniform composition and can be more durable. Ultimately, the better choice will depend on factors such as strength, density, and aesthetic preference.
