Conventional sources of energy is also called non-renewable sources of energy while non conventional sources of energy is called renewable sources of energy.
An example of conventional energy is coal, crude oil and natural gas. The advantage is the availability and affordability. The disadvantage is the level of air pollutants such as CO2 and CO it releases to the atmosphere which is harmful as it poses a risk of air borne illnesses.
An example of non conventional energy is the sun, wind , water etc. The advantage is that it reduces the risk of air pollution and keeps the environment clean as no toxic substances are being released into the atmosphere when used.

Oceanic and continental plates are colliding.
Explanation:
On the image, we can see an oceanic plate on the left, and a continental plate on the right, moving toward each other and colliding. Because the two plates have different densities, thickness, and elevation, one of the subducts below the other, that being the oceanic plate. As the oceanic plate subducts below the continental plate, it gradually moves down in the mantle layer, getting melted, recycled, and maybe the same material be pushed toward the surface again.
On the plate boundary, convergent in this case, there is intense geological activity. Magma manages to rise through the cracks and gaps, and it forms volcanoes, creating a continental volcanic arc. Also, there are lot of earthquakes at such boundaries, as there is constant adjustment of the crust.
Such boundaries can be found between the:
- Pacific and North American plates
- Pacific and Eurasian plates
- Pacific and Australian plates
- Pacific and Philippine plates
- Nazca and South American plates
- Cocos and North American plate
