Assuming this involves another form of shifting tectonic plates, the answer would be earthquakes. Another form of the question is asking for continental drift.
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.

Dams are important because:
They provide water for domestic, industry and irrigation purposes.
Dams often also provide hydroelectric power production and river navigation.
Domestic use includes everyday activities such as water for drinking, cooking, bathing, washing, and lawn and garden watering.
Dams and their reservoirs provide recreation areas for fishing and boating.
They help people by reducing or preventing floods. During times of excess water flow, dams store water in the reservoir; then they release water during times of low flow.
