Question

I'm doing a CER for science about volcanoes. Please see if I am doing it correctly and comment on any suggestions.


Question: What role do volcanoes play in the flow of energy and cycling of matter on Earth?

Claim:
Volcanoes play an important role in the flow of energy and cycling of matter on Earth for they part of the rock cycle and plate movement.


Evidence: (need at least 3 pieces of evidence)

1) A piece of evidence that can prove this is the rock cycle. Based on my observations, when magma rises or an eruption occurs, the magma cools down and it forms igneous rocks. From there, the process of weathering and erosion occur starting the process all over again.

2)Another piece of evidence that can prove this are the plate structures. Based on our Volcanoes are related to three types of tectonic structures: convergent plate boundaries, divergent plate boundaries and hot spots. When volcanoes erupt or magma rises it causes one of the three plate structures to occur by pushing old crust away.

3)Magma inside of the volcano is considered as geothermal energy, which means that it uses heat stored from heat trapped beneath the Earth's surface to generate electricity.

4)Based on a class popcorn read, plate movements continually bring new rock above ground, where the rock is exposed of weathering and erosion.The resulting sediments form thin layers soon creating rock.

Reasoning:
1) A logical conclusion we can draw from this evidence is that volcanoes play an important role in the rock cycle because the magma that comes from the mantle was once melted metamorphic rocks or sediments that have been pushed deep into the mantle and when it cools down it is igneous. In other words, the rock cycle starts with igneous rocks.

2) Considered together, the fact that volcanoes are related to convergent boundaries, divergent boundaries, and hot spots, shows that volcanoes volcanoes play are part of the rock cycle and plate movements and that The plate movements bury all rocks underground where the rocks are exposed to heat and pressure. If the heat and pressure are great enough it causes metamorphism. Plate movements can also help transport metamorphic rocks far from where it formed clearly demonstrates that Volcanoes play an important role in the flow of energy and cycling of matter on Earth for it is part of the rock cycle and plate movement.

3) The fact that volcanoes are known as geothermal energy and use heat stored from heat trapped beneath the Earth's surface to generate electricity shows that volcanoes play an important role in the flow of energy and cycling of matter on Earth for it is part of the rock cycle and plate movement since geothermal energy refers to the magma in volcanoes, and magma helps start the rock cycle and plate movement ( if the eruption is strong enough).

4) Based on this evidence we can conclude that volcanoes play an important role in the flow of energy and cycling of matter on Earth for it is part of the rock cycle and plate movement since when the plate movement occurs it causes erosion and weathering to occur allowing the rock cycle to continue.

Good job mate it's correct
