System Interactions and Feedback Loops

Front

What is a feedback loop?

Back

A feedback loop is a process in which the output of a system influences its own input, creating a cycle of cause and effect.

Front

What is a positive feedback loop?

Back

A positive feedback loop amplifies changes or increases the output of a system, leading to further change in the same direction.

Front

What is a negative feedback loop?

Back

A negative feedback loop counteracts changes, promoting stability by reducing the output of a system when it deviates from a set point.

Front

Define the hydrosphere.

Back

The hydrosphere includes all water on Earth, encompassing oceans, lakes, rivers, groundwater, and water vapor in the atmosphere.

Front

What spheres interact during an earthquake causing a landslide?

Back

The interaction occurs between the Geosphere and Geosphere.

Front

What is the role of vegetation in preventing erosion?

Back

Vegetation stabilizes soil and reduces erosion by anchoring the soil with roots and absorbing water.

Front

How does deforestation contribute to climate change?

Back

Deforestation leads to increased carbon dioxide levels in the atmosphere, contributing to global warming.

Front

What is the significance of the biosphere?

Back

The biosphere encompasses all living organisms and their interactions with the environment, playing a crucial role in ecosystem dynamics.

Front

Explain the interaction between the hydrosphere and geosphere.

Back

The hydrosphere interacts with the geosphere through processes like erosion, sediment transport, and the shaping of landforms by water.

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.
