Volcanic eruptions occur when magma rises upwards through ___ to reach the ____
Volcanoes eruption when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.
When Melting takes place?Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Volcanoes are the large volcanic buildings with long, and generally the conical shape, usually with a small crater on the summit and the steep flanks, that constructed by the interleaving of lava flows and the pyroclastic products emitted by one or more conduits.
Compound volcanoes are present in all regions of the volcanism, but it has in the plate convergence zones, where the tectonic plate subdows plunges toward the earth's mantle beneath another tectonic plate, that these volcanic buildings are the most abundant.
The magmatic expression of a converging plate margin environment is usually a series of sub-regularly spaced Compound Volcanoes, forming a sub-parallel volcanic arch to the tectonic fossa.
Therefore, Volcanic eruption when molten rock called magma rises to the surface.

The energy are refer to as clean because, they do not lead to any deposit of gasses that can affect the environment leading to environmental pollution. They have little or no side effects, no combustions or release of gases that are toxic or can deplete the environment as in the case of non- renewable energy.
13. With the massive amount of plant life, ample rainfall and favorable temperatures, you might think
that tropical rainforests would be large net producers of oxygen, and yet surprisingly, they are not! With
your knowledge of photosynthesis and cellular respiration, can you explain why this might be true?
Think about what happens when a leaf drops or fruit from a tree is eaten.
Answer:
Tropical rainforests such as the Amazon have been said to produce so much of Earth's oxygen when in fact this is not necessarily true.
Plants do indeed use Carbon dioxide during photosynthesis and the end product is Oxygen. The amount of oxygen produced however is more or less equivalent to the amount of Carbon dioxide taken in as atoms cannot be multiplied. With Carbon dioxide comprising only 0.04% of air, the oxygen produced is not as much as one would think.
After these trees produce Oxygen, they will also use it during respiration to produce energy which means that they would be sucking in most of the oxygen that they created. This would therefore reduce the net oxygen coming from these trees.
Another thing is that when plant life dies and is decomposed, the carbon dioxide that it stored from will be released back into the atmosphere. Leaves falling and fruits eaten will have this effect as well and since this happens a lot in tropical rainforests, their net oxygen production decreases.
