Confined aquifers are trapped between impermeable layers and recharge slowly, while unconfined aquifers are open to the surface and can recharge more quickly.

Front

What causes acid rain?

Back

Acid rain is caused by the mixing of air pollutants, such as sulfur dioxide and nitrogen oxides, with water vapor in the atmosphere, leading to a decrease in pH.

Front

What is the impact of acid rain on the environment?

Back

Acid rain can strip trees of leaves and needles, damage buildings and statues, and harm aquatic ecosystems by lowering the pH of water bodies.

Front

What is the significance of elevation in geography?

Back

Elevation refers to the height of a location above sea level, which can influence climate, vegetation, and human activities.

Front

What is the role of groundwater in the hydrosphere?

Back

Groundwater is a crucial component of the hydrosphere, providing water for drinking, irrigation, and maintaining ecosystems.

Front

What are the effects of over-exploitation of animals?

Back

Over-exploitation can lead to population decline, species extinction, and disruption of ecosystems.
