Answer:
atmosphere
Explanation:
The Earth is wrapped in a blanket of air called the 'atmosphere', which is made up of several layers of gases. The Sun is much hotter than the Earth and it gives off rays of light energy that travel through the atmosphere and reach the Earth's surface.
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.
The energy is generated by the semi-molten core of the earth which drives the convection currents in the mantle and which causes the plates to move in plate tectonics. James Hutton was the first geologist to intepret that the plutonic rocks on surface like granite were once molten.
Answer:
Both the Enlightenment and the Industrial Revolution were social processes that led to great changes in the societies of the time. Thus, the Enlightenment led to the adoption of liberal ideologies and greater exercise of rights by the societies of the time, which implied a limit to the powers of the authoritarian governments of the time; While the Industrial Revolution, in turn, led to the adoption of automated production processes that made most of the population begin to reside in urban centers, abandoning rural life.
These two processes, which occurred continuously, greatly modified the social composition of the societies of the time. Thus, European societies became eminently urban, with more combative populations and with a greater awareness of their rights and of the limits to the power of the rulers. This caused conflicts between the liberal sectors and the conservative sectors of the time to begin to occur, giving way to revolutions such as the American Revolution or the French Revolution.
