M2 L4 - Impacts of Human Activity on Landscapes

What is flooding?

• The cutting down of trees in a large area

• The destruction of forests by people

• The exhaustion of land by continuously growing crops on it

• The overflow of water onto normally dry land

How can the developing of urban areas lead to flooding?

• By cutting down trees in a large area

• By destroying forests

• By exhausting land through continuous crop growth

• By reducing natural water absorption and increasing runoff

What are landslides?

• The cutting down of trees in a large area

• The destruction of forests by people

• The overflow of water onto normally dry land

• The movement of a mass of rock, earth, or debris down a slope

How have landslides changed over time in terms of their causes?

• They have become less frequent due to human intervention

• They have become more frequent due to human intervention

• They have remained the same over time

• They have become less severe due to human intervention

What are four reasons humans may cut into or use land?

• To reduce flooding

• To promote biodiversity

• To create urban areas

• To conserve natural resources

What is overcropping?

• The cutting down of trees in a large area

• The destruction of forests by people

• The exhaustion of land by continuously growing crops on it

• The overflow of water onto normally dry land

What is overgrazing?

• The cutting down of trees in a large area

• The destruction of forests by people

• The exhaustion of land by continuously growing crops on it

• When livestock are allowed to graze on pasture for extended periods

What is deforestation?

• The cutting down of trees in a large area

• The destruction of forests by people

• The exhaustion of land by continuously growing crops on it

• The overflow of water onto normally dry land

What are examples of construction in relation to landscapes?

• Reducing natural water absorption

• Increasing runoff

• Urban development, mining, and infrastructure creation

• Promoting biodiversity

What is the potential impact of overcropping, overgrazing, and deforestation on landscapes?

• Reduced flooding

• Increased biodiversity

• Improved soil quality

• Degradation of ecosystems and loss of habitat
