comes from rain or other forms of precipitation from the atmosphere.

It does not seep or infiltrate into the ground, instead, it flows toward lakes, rivers, streams, reservoirs, and watersheds.

• ground water

• surface water

• surface runoff

• river runoff

Answer explanation

It does not seep or infiltrate into the ground, instead, it flows toward lakes, rivers, streams, reservoirs, and watersheds.

The water that flows through the land and into the bodies of water is called

• surface runoff

• river runoff

• ground water

• surface water

The water in the river that flows to the ocean.

• surface runoff

• ground water

• river runoff

• surface water

Another source of fresh water. it seeps or infiltrates into the pores of soil and cracks of rocks below the ground.

• river runoff

• surface runoff

• surface water

• ground water

Answer explanation

fresh water from ground water comes from rain and other forms of precipitation.

The tiny spaces or pores in the soil or rocks that are filled by water are collectively called

• zone of saturation

• water table

• aquifer

• aqueduct

It is called the upper surface of the zone which divides the line between the saturated rocks filled with water and the unsaturated rocks that can still absorb water

• zone of saturation

• aquifer

• water table

• aqueduct

The porous saturated layer of sand, gravel, and bedrock that can hold a great amount of water.

• water table

• zone of saturation

• aqueduct

• aquifer

Answer explanation

Aquifers are considered as great sources of groundwater that supply fresh water for human consumption.

Pipes for water to flow to a lower level.

• Ground water

• Zone of saturation

• Aquifer

• Aqueduct

A long period of no rain

• Drought

• Conservation

Is the wise use or management of natural resources like water, so that there will be enough for future use.

• Drought

• Conservation

Answer explanation

To have enough fresh water int the future, all of us sould be "water smart."

Practice the ways on conserving water.
