Answer:
Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.
Explanation:
Other Waterfall Facts:
Without similar protection, the next pool down began to erode, forming a vertical wall between the two—and thus, a waterfall. What's more, Crosby notes, these waterfalls lingered. Each lab-made cascade stuck around for about 20 minutes, a period of time that represents 10 to 10,000 years, according to the study
If the sun were to stop shining, then all the waterfalls in the world would eventually stop. It is the sun which provides all of the energy needed to lift water from the ocean to the head of the river valley so that waterfalls can continually have water falling over them.

Explanation:
<u>Formula for calculating the pressure at sea level, knowing the pressure at the station level
</u>
QNH = 1013.25 [((0.0065 / 288.15) * H) + (QFE / 1013.25) ^ 1 / 5,256] ^ 5,256
<u>From where</u>:
QNH: Value of the pressure at sea level to be calculated. QNH stands for the atmospheric pressure transmitted in the METAR parts of an airfield.
H: Altitude of the observatory with respect to sea level
QFE: Barometric pressure at station level

Answer: migrantes estão no caminho e não se sabe do estatus deles {exilados, fugitivos etc etc} e nem sempre sabemos o objetivo, ponto final ou destino deles. Imigrantes são pessoas que acabaram de chegar no país que lhes recebeu (expressao "imigrantes" descreve a perspectiva dos habitantes do pais que lhes recebeu). Emigrantes sao aqueles que abandonam o país (expressao "emigrantes" descreve a perspectiva do habitantes do país de origem).
Explanation: As três palavras tem significado diferente e sempre requerem compreensao. Migrante está no caminho, imigrantes está chegando ou já chegou, emigrante está abandonando o pais de origem.
