Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Glacial retreat leads to the loss of unique and fragile ecosystems that support specialized flora and fauna adapted to cold environments.

Multiple choice

Which of the following is NOT a potential impact of glacial retreat on downstream ecosystems?

  1. Changes in water quality

  2. Loss of aquatic biodiversity

  3. Increased agricultural productivity

  4. Alteration of riverine habitats
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

While glacial retreat can have various impacts on downstream ecosystems, increased agricultural productivity is not a direct consequence, as it is influenced by complex factors related to soil conditions, water availability, and agricultural practices.

Multiple choice

D Correct answer
Explanation

Water scarcity can lead to desertification, loss of biodiversity, and an increased risk of wildfires.

Multiple choice

What is the term for the loss of biodiversity?

  1. Extinction

  2. Deforestation

  3. Pollution

  4. Climate change
Reveal answer Fill a bubble to check yourself
A Correct answer
