FLASHCARD QUESTION

Front

What is Albedo?

Back

Albedo is the measurement of the amount of reflectivity of a surface, expressed as a percentage.

2.

FLASHCARD QUESTION

Front

What happens in a positive feedback loop?

Back

In a positive feedback loop, each action creates a consequence that amplifies the other action.

3.

FLASHCARD QUESTION

Front

Give an example of a positive feedback loop related to climate change.

Back

As the Earth warms, ice cover melts, exposing soil or water. Albedo decreases, leading to more energy absorption and further warming.

4.

FLASHCARD QUESTION

Front

What is a negative feedback loop?

Back

A negative feedback loop is a process that counteracts changes, helping to maintain stability, such as maintaining body temperature.

5.

FLASHCARD QUESTION

Front

How does Albedo affect global temperatures?

Back

Higher albedo means more sunlight is reflected, leading to cooler temperatures, while lower albedo means more sunlight is absorbed, leading to warming.

6.

FLASHCARD QUESTION

Front

What is the relationship between ice cover and albedo?

Back

Ice cover has a high albedo, reflecting sunlight. When ice melts, the lower albedo of water or soil leads to increased absorption of heat.

7.

FLASHCARD QUESTION

Front

What is an example of a negative feedback loop in nature?

Back

An example is the regulation of body temperature: when the body overheats, mechanisms like sweating are activated to cool it down.
