Answer:
C. movement of the Earth’s plates
Explanation:
Volcanoes and earthquakes sometime occur in Canada's western ranges because of the movement of the Earth's plates.
- Plate tectonics is responsible for the volcanic activities which brings magma to surface from the asthenosphere.
- Also, earthquakes are products of plate tectonics.
- The differential movement caused sudden breakage of the plate and releases are sudden burst of energy.
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.
