Answer:
The greater the amount of silica in magma, the more viscous the magma is. The magma thus solidifies quicker as well.
Answer: two solar eclipses separated by one Saros cycle will have the same geometric characteristics (they will both be total, or partial or annular).
A Saros is a period of time of about 18 years 11 days and 8 hours and represents the time needed for the system composed by Moon, Earth, and Sun to return to its initial position.
Indeed, this is due to a natural harmony of the Moon’s motion: it takes 29.53 days to complete one orbit around Earth (Synodic Month), it takes 27.21 days to pass from the same node of its orbit (Draconic Month) and it takes 27.55 days to go from perigee to perigee (Anomalistic Month); the composition of these three motions gives one Saros of around 6585.3 days, composed by 223 Synodic Months, 239 Anomalistic Months and 242 Draconic Months (with a precision of few hours).
It has been observed that after one Saros cycle Moon, Earth and Sun are in the same initial position, therefore an eclipse occurring on day 1 of two consecutive Soros cycles would have the same geometric characteristics, which means that one Saros can be considered the periodicity of solar and lunar eclipses.
Due to the fact that a Saros is not composed by a whole number of days (we have a remainder of 8 hours), the two eclipses won’t be visible from the same location on Earth due to the rotation around its axis. It takes about 3 Soros for this to happen.

Explanation:
Around 1 million years ago, the first of a few glaciers moved south into what is now Ohio. Approximately 2/3 of the state was covered to their maximum extent. Glaciers scraped a lot of Ohio's surface, including its bedrock. They also left deposits of clay, sand, gravel, and rock as they melted back. During this period, humans appeared in what we now call the "Old World." At some point around the end of the Quaternary Period, groups of people migrated to the "New World," and eventually reached what would later become Ohio.
Answer:
Try to avoid using too many plastics.
Plastic waste is not only damaging to the water when broken down, but due to the harm done to marine life, it can also spread death and decay in the water.
