Earth Interior

In earth we have three types of sphere's which are lithosphere, Hydrosphere, Atmosphere.
Lithosphere is the solid part of earth including crust and mantle. Earth has two kind of crust one is oceanic and continental crust. Earth crust are natural. Hydrosphere is the liquid part of the earth. The atmosphere is the gassy part of earth.

The center of earth has many layers. The inner core of the earth is solid and hot as the surface of the sun. The outer core is the boundary for inner core, which is liquid part of earth made out of iron. The mantle that is the root of volcano. The mantle is the melted rock that known as magma creates lava from underneath the crust. The crust is the broken tracks of earth. Earth has two kind of crust one is oceanic and other is continental crust. Earth crust are natural. Continental crust are crust that are on dry land. oceanic crust are under sea broken land. This elements of earth are important to study because this cause explosion, earth quakes eruption, mainly to know what condition or situation we are living on. 

The Ring of Fire. :O

Shows the location where Ring Of Fire takes place.

Ring of fire is an area under sea where most frequent earthquake eruption and tsunami happens. 
Ring of fire is located around the pacific ocean.
Ring of fire is very significance because this is what creates volcano, earth eruption and high level explosion on earth. Islands are created Hawaii is a island created by the ring of fire. Ring of fire basically lava that is created by magma.

Mountain Building

Mountains are formed  when two continental crust are pushed together, also known as the convergent boundary. Convergent boundary helps to push two plates together which creates mountains. Dome is formed by magma pushing up from underneath the mantle. Mantle is a layer between the crust and the outer core. 

Mantle is liquid layer part of inner earth and creates magma. Folded are who land pushed together, created because of convergent boundary. Fault blocks are when pressure pull rocks apart and some faults goes up and some faults go down. After volcano explode and die they are no longer active also can be described as ring of fire. Volcano fire comes from the liquid magma made out of malted rock.
