Answer:
the increase in overpopulation depends on living conditions, waves of migration, unemployment, and thanks to the high birth rate there is much overpopulation.
Answer: Jupiter is the fifth planet in the solar system from the Sun and the largest in the Solar System. It is a gas giant with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. It has 67 moons and has rings that aren't too visible but still there. Jupiter is the fourth brightest object in the solar system and has the shortest day of all planets. Jupiter orbits the Sun once every 11.8 Earth years.

<u>Answer:</u>
<u>The Continental drift</u> is the displacement of continental masses relative to each other. This hypothesis was developed in 1912 by Alfred Wegener, who affirmed <u>that thousands of years ago there was a single and unique supercontinent, called </u><u>Pangea</u><u>, which later became separated.
</u>
His formulations were based mainly on the way in which the forms of the continents seem to fit on each side of the Atlantic Ocean, such as Africa and South America. He also took into account the distribution of certain fossils that coincided in continents far from each other.
<h2>
At first this approach was discarded by most of his colleagues, because <u>
his theory lacked a logical and geological explanation for its epoch. </u></h2><h2>
</h2>
He proposed that the continents move on another denser layer of the Earth that made up the ocean floor. But it was not until the 1960s, with the development of the theory of tectonic plates, that the movement of the continents could be adequately explained.
The correct options are:
the thinnest layer
-The crust is at most 60km while the other parts such as mantle can get to 2900km.
made of large pieces called plates
-The crust is indeed formed by different plates, including continental and oceanic, where they move according to the convection current of magma
mostly made of silicon dioxide
- The crust is made up of 59% of silica dioxide.
the outermost layer of the earth
- This is correct.
Hope it helps!
