• A method of measuring rainfall.

• A geographical term for a water shortage.

What is a reservoir?

• A small pond used for recreational activities.

• A large natural or artificial lake used to store water for various purposes, including drinking water, irrigation, and hydroelectric power.

What is conservation of water?

• Using water in excess without concern for future availability.

• Conservation of water involves using water efficiently and responsibly to ensure its availability for future generations.

• Ignoring water usage to save time and resources.

What is pollution of groundwater?

• Pollution of groundwater occurs when harmful substances, such as chemicals or waste, seep into the ground and contaminate the water supply.

• Pollution of groundwater is the process of purifying water by removing contaminants.

• Pollution of groundwater refers to the natural filtration of water through soil layers.

What is the difference between point source and non-point source pollution?

• Point source pollution comes from multiple, diffuse sources, while non-point source pollution comes from a single, identifiable source.

• Point source pollution is always more harmful than non-point source pollution.

• Point source pollution comes from a single, identifiable source, while non-point source pollution comes from multiple, diffuse sources.

What does percolation refer to in the context of groundwater?

• The process by which water evaporates from the surface of the earth.

• The process by which water moves through the soil and rock layers, eventually reaching the water table.

• The process of water being absorbed by plants from the soil.

• The process of water flowing over the surface of the ground without being absorbed.

What is runoff?

• A type of precipitation that falls as rain or snow.

• Water that flows over the surface of the land and eventually washes into rivers, streams, and other waterways.

• Water that is absorbed by the soil and used by plants.
