Explanations: answer key for all 10 questions

Q1: What is erosion?
Answer: The wearing away and moving of rock and soil
Weathering breaks rock; erosion moves it.
Q2: Which river carved the Grand Canyon?
Answer: Colorado River
It took millions of years.
Q3: Which landforms are shaped mainly by wind erosion?
Answer: Sand dunes and rock arches in deserts
Sand blasts rocks.
Q4: What did glaciers carve in Norway?
Answer: Fjords
Glaciers carve U-shaped valleys.
Q5: Which coastal features form from wave erosion?
Answer: Sea caves, arches and stacks
The Twelve Apostles are sea stacks.
Q6: What forms where a river drops sediment at its mouth?
Answer: A delta
The Nile delta is famous.
Q7: Which US park has over 2,000 natural stone arches?
Answer: Arches National Park
Erosion shaped the sandstone.
Q8: How do plants reduce erosion?
Answer: Roots hold soil
Deforestation increases erosion.
Q9: Freeze-thaw weathering happens when what occurs?
Answer: Water freezes and expands in cracks
It splits rocks apart.
Q10: What forms when a river cuts off a meander loop?
Answer: An oxbow lake
It is a curved lake.

Erosion Quiz – Forces That Shape the Land

Erosion is the process of wearing away rock and soil and carrying it elsewhere. Water, wind, ice, waves and gravity are the main forces, working slowly over thousands to millions of years.

Erosion creates spectacular landscapes. Rivers carved the Grand Canyon, glaciers sculpted fjords and U-shaped valleys, wind shaped desert arches and waves cut sea caves and stacks. Eroded material builds deltas, beaches and floodplains.

Erosion can also harm farmland and coasts, removing fertile soil and threatening buildings. Planting vegetation, building terraces and protecting wetlands help slow it.
