Constructive and Destructive Forces

Front

What is the process of beach nourishment or reclamation?

Back

Beach nourishment or reclamation is the process of adding sand or sediment to a beach to combat erosion and increase beach width.

Front

What is the difference between constructive and destructive forces?

Back

Constructive forces build up landforms, while destructive forces wear down and erode landforms.

Front

What is an example of a destructive process related to waves?

Back

Waves eroding away the sand of the beach is an example of a destructive process.

Front

What are two methods farmers use to prevent soil erosion?

Back

Farmers use contour plowing on hills and terrace farming on mountains to prevent soil erosion.

Front

Define weathering in geological terms.

Back

Weathering is the breakdown of rocks into smaller particles due to various physical, chemical, or biological processes.

Front

What is an example of a constructive force in nature?

Back

A glacier depositing large amounts of sediment after it has melted is an example of a constructive force.

Front

How does terrace farming help in preventing erosion?

Back

Terrace farming helps prevent erosion by creating flat areas on slopes, reducing runoff and soil loss.

Front

What role do waves play in coastal erosion?

Back

Waves contribute to coastal erosion by continuously wearing away the shoreline and transporting sand and sediment.

Front

What is the impact of human activities on erosion?

Back

Human activities, such as deforestation and urban development, can increase erosion by disturbing the soil and vegetation.

Front

What is the significance of contour plowing?

Back

Contour plowing is significant because it follows the natural contours of the land, reducing soil erosion and water runoff.
