Bio-Erosion and Its Impact

The video discusses the phenomenon of bio-erosion, using Hoboro Island as a case study. The island is being eroded by crustaceans, which bore into rocks, accelerating natural erosion. Bio-erosion affects various ecosystems, including coral reefs, and is influenced by climate change. The video also highlights the importance of understanding bio-erosion for conservation efforts. Additionally, it includes a sponsor message from Brilliant, promoting their educational courses.

What is the main reason for Hoboro Island's erosion?

• Wind and waves

• Human activity

• Crustaceans boring into rock

• Rising sea levels

What is bio-erosion?

• Erosion caused by human activities

Which of the following is NOT an example of bio-erosion?

• Plant roots fracturing rocks

• Penguins wearing down bedrock

• Microbes breaking down minerals

• Wind eroding sand dunes

How do isopods affect human structures?

• By making them more durable

• By strengthening them

• By causing microblastic pollution

• By protecting them from erosion

Which organism can erode over a thousand kilograms of coral per year?

What is the impact of climate change on coral reefs?

• It balances erosion and accumulation

• It increases coral growth

• It has no impact

• It tips the balance towards erosion

What is one benefit of bio-erosion on coral reefs for humans?

• It creates white sand beaches

• It reduces ocean acidity
