Constructive and Deconstructive Explain how natural processes (including weathering, erosion, deposition, landslides, volcanic eruptions, earthquakes, and floods) affect Earth’s oceans and land in constructive and deconstructive ways.
A river overflows its banks due to excessive rains and floods the surrounding land. After the rain stops, the water returns to the river’s original path. However, the land surrounding land is now covered with a new soil. This is an example of deposition of sediment – constructive force.
A fast moving stream deposits what type of material first?
How does freezing of water cause weathering of rocks?
It cracks them .
How can a volcanic eruption be both constructive and destructive?
The lava and ash from volcanic eruptions can destroy forests and bury fields. The magma and lava can form new tops of the volcanic mountains or build up the land around the volcano. For example, a volcano under the sea, a seamount, erupts and erupts and erupts, building new land. This repeating eruption creates islands such as Hawaii and Japan.
