The correct answer is - A. Devonian.
The Devonian is one of the seven periods of the Paleozoic Era. It lasted for 50 million years, from 410 million years ago until 360 million years ago. It is the period in which the first insects evolved, the first seeded plants, as well as the first land vertebrates. This period came after the Silurian period, and was followed by the Mississippian period.
This is false. different sides have different histories
Weather is determined by the values of meteorological factors: temperature, air umididatea, wind direction and speed, atmospheric pressure, air turbulence, the amount and type of precipitation. These factors are measured by specific instruments - thermometers, barometers, hydrometers, weathervane to The measured values over long periods of time (years or decades) statistically give us information about the climate of a region.
