Constructive and Destructive Processes

What causes landslides?

• Gravity alone

• Heavy rain, earthquakes, or volcanic activity

• Human activities such as construction

• Strong winds and storms

What is the difference between weathering and erosion?

• Weathering is the movement of materials, while erosion is the breaking down of rocks and minerals.

• Weathering is the breaking down of rocks and minerals, while erosion is the movement of those materials from one place to another.

• Weathering and erosion are the same processes that occur simultaneously.

• Weathering is the process of soil formation, while erosion is the process of rock formation.

How do rivers contribute to land formation?

• Rivers can erode land, creating valleys, and deposit sediment, building up new landforms like deltas.

• Rivers only erode land without creating any new landforms.

• Rivers primarily serve as a source of drinking water and do not affect land formation.

• Rivers are only responsible for flooding and have no role in land formation.

What is sediment?

• Small particles of rock, soil, and organic material that can be moved by wind, water, or ice.

• A type of large rock formation found in mountains.

• A liquid substance that forms during heavy rainfall.

• A mixture of gases found in the atmosphere.

What is the significance of the water cycle in erosion and deposition?

• The water cycle has no impact on erosion and deposition.

• The water cycle helps in the formation of mountains.

• The water cycle plays a crucial role in erosion and deposition by moving water, which can erode land and transport sediment.

• The water cycle only affects the climate, not erosion or deposition.

What role does wind play in shaping the landscape?

• Wind can erode surfaces and deposit sand, forming features like sand dunes.

• Wind has no effect on the landscape.

• Wind primarily causes rainfall and affects climate.

• Wind only affects the temperature of the environment.

What is a glacier?

• A large mass of ice that moves slowly over land, shaping the landscape through erosion and deposition.

• A type of rock formed from volcanic activity.

• A body of water that freezes during winter.

• A large sand dune found in deserts.

What is erosion?

• Erosion is the process of planting trees to prevent soil loss.

• Erosion is the wearing away of Earth's surface by water, wind, plants, and temperature.

• Erosion is the process of building up land through sediment deposition.

• Erosion is the movement of tectonic plates beneath the Earth's surface.

What are destructive processes?

• Natural processes that build up the Earth's surface, such as volcanic eruptions and sediment deposition.

• Natural processes that break down the Earth's surface, such as erosion, landslides, and earthquakes.

• Processes that have no impact on the Earth's surface.

• Human activities that alter the landscape, such as deforestation and urbanization.

What are constructive processes?

• Natural processes that build up the Earth's surface, such as volcanic eruptions and sediment deposition.

• Processes that erode the Earth's surface, like weathering and erosion.

• Human activities that alter the landscape, such as construction and mining.

• Natural disasters that cause destruction, like earthquakes and tsunamis.
