I believe the best answer is C. i mean it has already made that progress, hints the term developed, not developing. i hope this helped, have an amazing day :)
What are the options for the question?
D. high and low levels of silica in the different type of lava.
Explanation:
The volcanoes have different types of explosions. Some tend to be highly explosive, some less explosive, some don't have explosions at all, while some have combinations of different eruptions. The reason for this diversity in the eruption types is mostly the composition of the magma, or rather how high is the silica content in it.
Basically, the higher the silica level in the magma the higher the explosiveness, and the lower the silica level the lower the chances of explosiveness. This is the case because the higher amount of silica makes the magma thicker, so the gasses are trapped and they explode, while when the lower silica content makes the magma less thick, so the gasses are not trapped and explosions are lacking.
Explanation:
High and low tides are caused by the Moon.
The Moon's gravitational pull induces something called the tidal force.
The tidal force causes Earth—and its water—to bulge out on its nearest and furthest sides from the Moon.
The Moon is responsible for high and low tides.
