What is erosion?
Erosion is the process by which soil and rock are removed from the Earth’s surface by natural processes such as wind or water.
What is transportation in the context of erosion?
Transportation is the movement of eroded materials such as soil and rock by agents like wind, water, or ice.
What is deposition?
Deposition is the process by which eroded materials are dropped or settled in a new location.
What is abrasion?
Abrasion is the wearing away of rock by friction caused by particles carried by wind, water, or ice.
What is attrition?
Attrition is the process by which eroded particles collide with each other, breaking into smaller pieces.
True or False: Erosion only occurs in one specific way.
False. Erosion can occur through various processes such as wind, water, ice, and gravity.
Fill in the blank: Transportation involves the movement of eroded materials by agents like ____, water, or ice.
wind
What is the main difference between erosion and deposition?
Erosion involves the removal of materials from the Earth’s surface, while deposition involves the settling of eroded materials in a new location.
How does abrasion contribute to erosion?
Abrasion wears away rock surfaces, contributing to the process of erosion.
What is the role of attrition in erosion?
Attrition breaks down eroded particles into smaller pieces, aiding in the erosion process.
Which of the following is not a common agent of transportation in erosion: wind, earthworms, water, ice?
earthworms
What is the primary cause of erosion on Earth?
Water is the primary cause of erosion on Earth, through processes like rivers, oceans, and rainfall.
How does deposition contribute to landforms?
Deposition can create new landforms like deltas, beaches, and alluvial plains by depositing eroded materials in specific areas.
What is the difference between weathering and erosion?
Weathering is the breakdown of rocks into smaller particles, while erosion involves the removal and transportation of those particles.
What role does gravity play in erosion?
Gravity can cause materials to move downhill, leading to erosion processes like mass wasting and landslides.
How can human activities contribute to erosion?
Human activities such as deforestation, construction, and mining can accelerate erosion by removing vegetation and disrupting natural processes.
What is the term for the process of eroded particles settling out of a transporting medium?
Deposition
True or False: Erosion always results in the loss of soil and rock material.
True
Fill in the blank: Abrasion is the wearing away of rock by friction caused by particles carried by wind, water, or ____.
ice
What are some examples of landforms created by erosion and deposition?
Examples include valleys, canyons, sand dunes, and river deltas.
How does attrition differ from abrasion in erosion processes?
Attrition involves eroded particles colliding with each other and breaking into smaller pieces, while abrasion is the wearing away of rock surfaces.
What is the term for the process of eroded materials being carried away from their original location?
Transportation
What is the main force driving erosion by water?
The force of flowing water, such as in rivers and streams, drives erosion by carrying away soil and rock particles.
How does erosion impact the landscape over time?
Erosion can reshape the landscape by creating landforms like valleys, canyons, and coastal cliffs through the removal and transportation of materials.
