Erosion Identification

Which landform is most likely to be affected by erosion: a mountain or a desert?

• ocean

• lake

• mountain

• forest

What is the main difference between weathering and erosion?

• Weathering and erosion both involve moving rocks.

• Weathering only affects small rocks, while erosion affects large rocks.

• The main difference between weathering and erosion is that weathering breaks down rocks, while erosion moves the broken pieces.

• Weathering is caused by water, while erosion is caused by wind.

Which of the following is an example of erosion: a river carving a canyon or a tree growing taller?

• a river drying up

• a river carving a canyon

• a mountain forming

• a volcano erupting

How does wind contribute to erosion?

• Wind reduces the impact of erosion by compacting soil particles.

• Wind promotes the growth of vegetation that prevents erosion.

• Wind creates barriers that prevent erosion from occurring.

• Wind carries loose particles and causes them to collide with surfaces, leading to erosion.

Why is erosion considered a natural process?

• Erosion is caused by aliens

• Erosion is a man-made process

• Erosion is caused by human activities

• Erosion is caused by natural forces like wind, water, and ice.

Which type of erosion is caused by gravity pulling rocks and soil downhill?

• Water erosion

• Wind erosion

• Mass Movement

• Chemical erosion

What role does water play in the process of erosion?

• Water transports sediment, breaks down rocks, and shapes the land.

• Water creates new landforms

• Water increases the stability of rocks

• Water reduces the speed of erosion

In what ways can human activities accelerate erosion?

• Waste management, wildlife conservation, organic farming

• Deforestation, overgrazing, construction, mining, and improper agricultural practices

• Reducing carbon emissions, planting trees, using renewable energy

• Recycling, sustainable farming, controlled burning

Which of the following is NOT a result of erosion: formation of sand dunes or creation of volcanic islands?

• melting of glaciers

• erosion of mountains

• creation of volcanic islands

• formation of sand dunes

Why is it important to study and understand erosion?

• To promote the growth of invasive species

• To predict and prevent soil degradation, manage water resources effectively, protect infrastructure, and preserve natural habitats.

• To increase erosion rates for agricultural purposes

• To accelerate the depletion of natural resources
