Review Constructive/Destructive Forces

Construct an argument supported by scientific evidence to explain how a delta is formed at the mouth of a river. Consider both constructive and destructive processes in your explanation.

• A delta is formed solely by the deposition of sediments carried by the river.

• A delta is formed by the deposition of sediments, which is a constructive process, and the erosion of riverbanks upstream, which is a destructive process.

• A delta is formed by the erosion of the riverbed, which is a destructive process.

• A delta is formed by the impact of organisms living in the river.

Develop a simple interactive model to demonstrate how sand dunes are formed by wind. What data would you collect to illustrate this process?

• The speed and direction of the wind, and the size and shape of the sand particles.

• The temperature of the sand and the humidity of the air.

• The color of the sand and the time of day.

• The presence of vegetation and the type of animals in the area.

Construct an argument to explain how mountains are formed by both constructive and destructive processes.

• Mountains are formed only by the constructive process of volcanic activity.

• Mountains are formed by the constructive process of tectonic plate collision and the destructive process of erosion.

• Mountains are formed by the destructive process of weathering.

• Mountains are formed by the impact of organisms.

• The color of the rock and the time of day.

• The temperature of the rock and the presence of animals.

• The height of the rock and the distance from the sea.

Construct an argument to explain how volcanoes can be both constructive and destructive.

• Volcanoes are only destructive because they destroy everything in their path.

• Volcanoes are constructive because they create new land and destructive because they can cause widespread damage.

• Volcanoes are only constructive because they create fertile soil.

• Volcanoes are neither constructive nor destructive.

Construct an argument to explain how the impact of organisms can be both constructive and destructive to surface features.

• Organisms are only destructive because they cause erosion.

• Organisms are constructive because they can build structures like coral reefs and destructive because they can cause erosion.

• Organisms are only constructive because they create habitats.

• Organisms have no impact on surface features.
