  Earth's size and composition led to volcanic activity, which in turn, had a major impact on Earth's geographical relief

Explanation:

Magmatic material expelled to the surface is responsible for the formation of volcanic relief. Materials from within the earth can be found in three states: solid, liquid and gaseous. Importantly, volcanism, together with tectonism and earthquake, comprise internal relief shaping agents.

The phenomenon in question most often happens in places where tectonic plates meet. The magmatic material comes to the lava-shaped surface, it covers large area around. Volcanism as a relief shaping agent is responsible for the rise of mountains and plateaus. In the formation of mountains, all the lava that is emitted is stored near where all the magmatic material comes out. Thus, after various processes of this nature, the mountain is constituted.

i believe that if you say you can, you cant and if you say you can't your right. i believe i can do anything i set my mind to. i've applied this with my everyday life. it me get motivated to do stuff.for example, i apply this to do school. if i believe i can finish a whole class in a couple of week's i will be motivated to do the class until i finish it, and if i believe i can't, i will get distracted and do other stuff besides doing my work. it changed me by believing i can accomplish anything i set my mind to.
