Front

What is the pH level of pure water?

Back

Pure water has a neutral pH, meaning it is neither an acid nor a base.

Front

Which sediment is more effective at filtering groundwater?

Back

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water molecules to stick to each other due to hydrogen bonding.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water molecules to stick to other substances.

Front

What is the significance of water being a universal solvent?

Back

Water is called a universal solvent because it can dissolve many substances, making it essential for biological processes.

Front

How does temperature affect the density of water?

Back

As water cools, it becomes denser until it reaches 4°C; below this temperature, it expands and becomes less dense.

Front

What is the role of water in the hydrosphere?

Back

Water plays a crucial role in the hydrosphere by supporting ecosystems, regulating climate, and shaping geological features.
