Answer:
6 THINGS THAT MAKE LIFE ON EARTH POSSIBLE
Earth is well equipped as a planet and ideally placed in our solar system and galaxy to support life as we know it. The product of some 4.6 billion years of cosmic construction, our planet is flush with life thanks to a fortuitous set of conditions.

It is all about the tilt of the Earth’s axis. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!
During the summer, the sun’s rays hit the Earth at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.
During the winter, the sun’s rays hit the Earth at a shallow angle. These rays are more spread out, which minimizes the amount of energy that hits any given spot. Also, the long nights and short days prevent the Earth from warming up. Thus, we have winter!

Explanation:
Regional metamorphisim occurs as a result of tectonic activity and is characterized with low temp and high pressure conditions over a large area while contact metamorphism occurs intrudes existing rocks.
There are many push factors when it comes to emigration, but first, a push factor is something that will make someone want to voluntarily leave because of the things happening in their country. Examples of some push factors are a lack of job opportunites, war, famine, and instability in the country. Examples of push factors in real life happening today are...
1. Syria - war/conflict from the Syrian Civil War
2. Venezuela - crime, and politcial and economic instability
3. North Korea - harsh laws and punishments, dictatorship, and the regime/totalitarianism
Hope this helps, have a BLESSED and wonderful day! :-)
