Are nationalism and colonization the same thing?

Nationalism is a way of thinking that says that some groups of humans, such as ethnic groups, should be free to rule themselves. Nationalists think that the best way to make this happen and avoid control or oppression by others is for each group to have their own nation.

Colonialism is a process by which a country takes over new land, and reorganizes that land's economy to benefit the colonizing power, rather than to benefit the residents of the colony. Colonialism works to funnel wealth back to the colonizer while inhibiting the development of the colony.

Magma is outside the volcano  and lava is inside the volcano. 

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.
