Answer:
Desertificación.
Explicación:
La quema de combustibles en industrias y vehículos produce gas dióxido de carbono en una gran cantidad que contamina el aire. Este gas de dióxido de carbono es un gas de efecto invernadero que se acumula en la atmósfera y bloquea la radiación solar que va al espacio después de la refección, lo que provoca un aumento de la temperatura de la tierra y una condición de sequía que conduce a la desertificación. Debido a esta desertificación, la vegetación se elimina por falta de agua suficiente.
They are different because the sea has moist airs and so it makes the humidity go up
SCIENCE
If the coast-to-coast distance is about 2900 miles, it will take about ...
... (2900 mi)/(186000 mi/s) ≈ 15.6 ms
for the signal to travel coast-to-coast at light speed.
_____
There are time delays due to the amplifiers and repeaters required in the path, and due to the fact that the signals don't actually travel at the speed of light in a wire.
A test of internet speed between Seattle and Washington, DC shows a round-trip time of about 87 ms when traffic is light. Modern communication channels tend to be faster than the telegraph (especially when measured in words per minute).
