Table sugar dissolves in water because when a sucrose molecule breaks from the sugar crystal, it is immediately surrounded by water molecules. The sucrose has hydroxyl groups that have a slight negative charge. ... Sand can't dissolve in waterbecause the 'spaces' in between the water particles. :)
Directly most of alternative energy is gained from water. But eventually almost all energy on earth comes from sun. Without sun we wouldn't have rivers (no rains), we wouldn't have wind (let alone oil or coal) etc. We would only have geothermal and seismic power.
Direct sun radiation conversion (via collectors or photovoltaic) is not very popular yet. But indirectly sun is the main source of earths energy.
The two poles of magnets must have equal and opposite strength so they cannot be separated

Answer:
Strato-volcano
Explanation:
Strato-volcanoes are usually characterized by the presence of steep-sided slopes, with distinct craters, and are frequently erupted and conical in appearance. This type of volcano is generally felsic in nature. Due to the presence of high silica content, the magma being highly viscous, moves at a relatively slower rate. These are highly explosive and produce a large number of pyroclastic materials, lava flow, volcanic ashes, and gases.
They are also commonly considered as the composite volcano, and are comprised of alternating tephra and solidified lava layers.
