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.
Answer:
- Reduced snow accumulations
- Earlier snowmelt in the Spring
- Spring flooding
- Less water in streams
- Reduced water availability
Explanation:
Less snow will fall in Winter due to the higher temperatures and, thus, will not accumulate. When there is less accumulated snow on the ground and the snowpack is thinner, then the snowmelt will occur earlier and faster in the Spring.
Quicker snowmelt in the Spring will result in rivers overflowing their banks because they cannot hold such a rapid influx of water. Rapid water cycle runoff will cause Spring flooding.
The snowpack will, therefore, be depleted early in the Spring season, and due to the earlier and faster snowmelt, there will be less water in the streams during the Summer.
The consequential lack of slow mountain snowmelt during the summer season will result in rivers flowing much less vigorously and with less volume over water. This means that downriver communities will face summer water shortages.
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subduction back into the earth.
